MAINTENANCE
PERIODIC MAINTENANCE CHART
Careful periodic maintenance will help keep your vehicle in the safest, most reliable condition. Inspection,
adjustment and lubrication of important components are explained in the periodic maintenance chart.
Inspect, clean, lubricate, adjust and replace parts as necessary. When inspection reveals the need for
replacement parts, use genuine Polaris parts available from your Polaris dealer.
Service and adjustments are critical. If you’re not familiar with safe service and adjustment
procedures, have a qualified dealer perform these operations.
Maintenance intervals in the following chart are based upon average riding conditions and an average vehicle
speed of approximately 10 miles per hour. Vehicles subjected to severe use must be inspected and serviced more
frequently.
NOTE:
Severe Use Definition
G Frequent immersion in mud, water or sand
G Racing or race-style high RPM use
G Prolonged low speed, heavy load operation
G Extended idle
G Short trip cold weather operation
Pay special attention to the oil level. A rise in oil level during cold weather can indicate contaminants collecting
in the oil sump or crankcase. Change oil immediately if the oil level begins to rise. Monitor the oil level, and if
it continues to rise, discontinue use and determine the cause or see your dealer.
Maintenance Chart Key
The following symbols denote potential items to be aware of during maintenance:
H= CAUTION: Due to the nature of these adjustments, it is recommended this service be performed
by an authorized Polaris dealer.
"= SEVERE USE ITEM ----If vehicle is subjected to severe use, decrease interval by 50%
(Severe Use is defined as frequent vehicle immersion in mud, water or sand, racing or race- style high rpm
use, prolonged low speed - heavy load operation or extended idle. More preventative maintenance is
required under these conditions. Fluid changes, cable, chain and chassis lubrication are required more
frequently. For engine oil, short trip cold weather riding also constitutes severe use. Pay special attention
to oil level. A rising oil level in cold weather can indicate contaminants collecting in the oil sump or
crankcase. Change oil immediately and monitor level. If oil level begins to rise, discontinue use and
determine cause.)
E= Emission Control System Service (California).
NOTE: Inspection may reveal the need for replacement parts. Always use genuine Polaris parts.
WARNING: Improperly performing the procedures marked with a J could result in component failure and lead
to serious injury or death. Have an authorized Polaris dealer perform these services.

COMPRESSION TEST
NOTE: This engine does NOT have decompression
components. Compression readings will vary in
proportion to cranking speed during the test. Average
compression (measured) is about 150-200 psi during
a compression test.
A smooth idle generally indicates good compression.
Low engine compression is rarely a factor in running
condition problems above idle speed. Abnormally
high compression can be caused by carbon deposits
in the combustion chamber or worn, damaged
exhaust cam lobes.
Inspect camshaft and
combustion chamber if compression is abnormally
high.

MAINTENANCE
A cylinder leakdown test is the best indication of
engine condition. Follow manufacturer’s instructions
to perform a cylinder leakage test. (Never use high

MAINTENANCE
STEERING
The steering components should be checked
periodically for loose fasteners, worn tie rod ends, and
damage. Also check to make sure all cotter pins are
in place. If cotter pins are removed, they must not be
re-used. Always use new cotter pins.
G

Replace any worn or damaged steering components.
Steering should move freely through entire range of
travel without binding. Check routing of all cables,
hoses, and wiring to be sure the steering mechanism
is not restricted or limited. NOTE: Whenever steering
components are replaced, check front end alignment.
Use only genuine Polaris parts.
G
WARNING
Due to the critical nature of the procedures outlined in this chapter, Polaris recommends
steering component repair and adjustment be
performed by an authorized Polaris MSD--certified technician when replacing worn or damaged steering parts. Use only genuine Polaris
replacement parts.
Replace
any
worn
steering
components. Steering should move
freely through entire range of travel
without binding.
Elevate front end of machine so front
wheels are off the ground. Check for
any looseness in front hub / wheel
assembly by grasping the tire firmly
at top and bottom first, and then at
front and rear. Try to move the wheel
and hub by pushing inward and
pulling outward.
If abnormal movement is detected,
inspect the hub and wheel assembly
to determine the cause ( possible
loose wheel nuts or loose front hub
components).
One of two methods can be used to measure toe
alignment. The string method and the chalk method.
If adjustment is required, refer to following pages for
procedure.

METHOD 2: CHALK
1. Place machine on a smooth level surface.
2. Set handlebars in a straight ahead position and
secure handlebars in this position. NOTE: The
steering arm “frog” can be used as an indicator of
whether the handlebars are straight. The frog
should always point straight back from the
steering post.
3. Place a chalk mark on the center line of the front
tires approximately 10″ (25.4 cm) from the floor or
as close to the hub/axle center line as possible.
NOTE: It is important that the height of both
marks be equally positioned in order to get an
accurate measurement.
4. Measure the distance between the marks and
record the measurement. Call this measurement
“A”.
5. Rotate the tires 180° by moving vehicle forward or
backward. Position chalk marks facing rearward,
even with the hub/axle centerline.
6. Again measure the distance between the marks
and record. Call this measurement “B”. Subtract
measurement “B” from measurement “A”. The
difference between measurements “A” and “B” is
the vehicle toe alignment. The recommended
vehicle toe tolerance is 1/8″ to 1/4″ (.3 to .6 cm)
toe out. This means the measurement at the front
of the tire (A) is 1/8″ to 1/4″ (.3 to .6 cm) wider than
the measurement at the rear (B).

CLEANING & STORAGE OF
ATV
Stabilize the Fuel
Keeping your ATV clean will not only improve its
appearance but it can also extend the life of various
components. With a few precautions, your ATV can
be cleaned much like an automobile.
Fill the fuel tank. Add Polaris Carbon Clean Fuel
Treatment or Polaris Fuel Stabilizer. Follow the
instructions on the container for the recommended
amount. (Carbon clean will also reduce the possibility of
bacterial growth in the fuel system.) Allow 15-20
minutes of operation for the stabilizer to disperse
through the fuel in the tank and carburetor. Turn the fuel
valve off and drain the carburetor bowl.
Washing the ATV
Oil and Filter
Cleaning the ATV
The best and safest way to clean your ATV is with a
garden hose and a pail of mild soap and water. Use
a professional type washing mitten, cleaning the
upper body first and the lower parts last. Rinse with
water frequently and dry with a chamois to prevent
water spots. NOTE: If warning and safety labels are
damaged, contact your a Polaris dealer for free
replacement.
Polaris does not recommend the use of a high
pressure type car wash system for washing the ATV.
If a high pressure system is used, exercise extreme
care to avoid water damage to the wheel bearings,
transmission seals, body panels, brakes and warning
labels. NOTE: Grease all zerk fittings immediately
after washing, and allow the vehicle to run for a while
to evaporate any water that may have entered the
engine or exhaust system.
Waxing the ATV
Warm the engine and change the oil and filter. Follow
the procedure in this chapter for proper oil change.
Air Filter / Air Box
Inspect and clean or replace the pre-cleaner and air
filter. Clean the air box and drain the sediment tube.
Breather Filter
Inspect and clean or replace the breather filter.
Fluid Levels
Inspect the following fluid levels and change if
necessary: front gearcase; transmission; brake fluid
(change every two years or as required if fluid looks
dark or contaminated).
Drain the Recoil Housing
Remove the recoil housing drain plug and drain any
moisture.
Your ATV can be waxed with any non-abrasive
automotive paste wax. Avoid the use of harsh
cleaners since they can scratch the body finish.
Polaris offers a detailing kit for your ATV, see Page
2.7.
Storage Tips
CAUTION: Certain products, including insect
repellants and chemicals, will damage plastic
surfaces.
Use caution when using these
products near plastic surfaces.
Use Polaris Fogging Oil, following the instructions as
directed.
Storage Tips
1. Treat the fuel system with Polaris Carbon Clean.
Turn fuel petcock to ’OFF’.
2. To eliminate any fuel remaining in the carburetor,
run the engine until it stops. If Polaris fuel system
additive is not used, fuel tank, fuel lines, and
carburetor should be completely drained of
gasoline.
3. To access the plug hole, use a section of clear 1/4”
hose and a small plastic squeeze bottle filled with
the pre-measured amount of oil.
4. Remove the spark plug(s). Rotate the piston to
BDC and pour approximately two ounces of
Polaris oil into the cylinder.
See Page 2.7 for the part numbers of Polaris
products.
CAUTION: Starting the engine during the storage
period will disturb the protective film created by
fogging and damage could occur. Never start the
engine during the storage period.
Clean the Exterior
Make necessary repairs and then clean the ATV
thoroughly with mild soap and warm water to remove
all dirt and grime. Don’t use harsh detergents or high
pressure washers. Some detergents deteriorate
rubber parts. Use dish soap type cleaners only. High
pressure washers may force water past seals.
Polaris offers storage kits for you ATV, see Page 2.7
for the part numbers of Polaris products.
Fog the Engine
If you choose not to use Polaris Fogging Oil, perform
the following procedure.
NOTE: Do this carefully! If you miss the plug hole, oil will
drain from the spark plug cavity into the hole at the front
of the cylinder head, and appear to be an oil leak.
2.35
MAINTENANCE
5. Apply dielectric grease to the inside of the spark
plug cap and install the cap onto the plug.
6. Turn the engine over several times to ensure
coverage of piston rings, cylinder walls and
crankshaft bearings.
7. Treat the fuel system with Polaris Carbon Clean.
8. If Polaris fuel system additive is not used, fuel
tank, fuel lines, and carburetor should be
completely drained of gasoline. To eliminate any
fuel remaining in the carburetor, run the engine
until it stops.
Lubricate
Inspect all cables and lubricate with Polaris Cable
Lubricant. Follow lubrication guidelines in the
maintenance section of the service or owner’s manual
to completely grease and lubricate the entire vehicle
with Polaris Premium All Season Grease.
Storage Tips
Battery Storage
Remove the battery from the vehicle and ensure that
it’s fully charged before placing it in storage. See
Chapter 10 for instructions.
Engine Anti-Freeze
Test engine coolant strength and change if necessary.
Coolant should be replaced every two years. See
Page 2.18 for the proper test procedure.
Storage Area/Covers
Set the tire pressure and safely support the ATV with
the tires 1-2” off the ground. Be sure the storage area
is well ventilated, and cover the machine with a genuine
Polaris ATV cover. NOTE: Do not use plastic or coated
materials. They do not allow enough ventilation to
prevent condensation, and may promote corrosion and
oxidation.
Transporting the ATV
Follow these procedures when transporting the
vehicle.
1. Turn off the engine and remove the key to prevent
loss during transporting.
2. Always place the transmission in park and lock
the parking brake.
3. Turn the fuel valve off.
4. Be sure the fuel cap, oil cap and seat are installed
correctly.
5. Always tie the frame of the ATV to the transporting
unit securely using suitable straps or rope.

800 EFI Exhaust Canister Maintenance
The exhaust canisters on Polaris 800 EFIs are
ceramic coated. To maintain a beautiful finish and
prevent corrosion, periodic maintenence is required.
DO NOT use caustic chemicals to clean, as they may
damage the finish.
1. Wash any accumulated mud or debris from the
canisters with a soft brush and soapy water.
2. Use a cleaner, such as HPC HiPerWasht to
clean away any remaining grime, salts or oils.
3. If the canisters are stained from oils or other
fluids, use fine steel wool with HPC Liquid Bufft
Cleaner and Polish to remove the stain.
4. After removing the stains, polish using Liquid Buff
and a soft cloth.
Repeat this procedure as often as desired to maintain
the canister’s finish.

Recommended Coolant
Use only high quality antifreeze/coolant mixed with
distilled water in a 50/50 or 60/40 ratio, depending on
freeze protection required in your area. CAUTION:
Using tap water in the cooling system will lead to a
buildup of deposits which may restrict coolant flow and
reduce heat dissipation, resulting in possible engine
damage. Polaris Premium 60/40 Antifreeze/Coolant is
recommended for use in all cooling systems and comes
pre-mixed, ready to use.
FLOW
Never remove radiator cap when engine is
warm or hot. The cooling system is under
pressure and serious burns may result. Allow
the engine and cooling system to cool before
servicing.
1. Remove front cover.
2. Remove recovery bottle hose from coolant filler
neck.
3. Connect a Mity Vact (PN 2870975) to the filler
neck nipple and pressurize system to 10 psi. The
system must retain 10 psi for five minutes or
longer. If pressure loss is evident within five
minutes, check the radiator, hoses, clamps and
water pump seals for leakage.

Engine Break In Period
The break in period for a Polaris ATV engine is defined
as the first ten hours of operation, or the time it takes
to use two full tanks of gasoline. No single action on
your part is as important as a proper break in period.
Careful treatment of a new engine will result in more
efficient performance and longer life for the engine.
Perform the following procedures carefully.
CAUTION
Use only Polaris Premium 0--40W All Season
synthetic oil or equivalent. Never substitute or
mix oil brands. Serious engine damage and
voiding of warranty can result.
Do not operate at full throttle or high speeds for
extended periods during the first three hours of
use. Excessive heat can build up and cause
damage to close fitted engine parts.
1. Fill fuel tank with unleaded or leaded fuel which
has a minimum pump octane number of 87= (R+
M)/2.
2. Check oil reservoir level indicated on dipstick.
Add oil if necessary.
SAFE
ADD 8 OZ
3. Drive slowly at first to gradually bring engine up to
operating temperature.
4. Vary throttle positions. Do not operate at
sustained idle or sustained high speed.
5. Perform regular checks on fluid levels, controls
and all important areas on the vehicle.
6. Pull only light loads during initial break in.
7. Change break in oil and filter at 20 hours or 200
miles.

CYLINDER HONE SELECTION
AND HONING PROCEDURE
CAUTION:
A hone which will straighten as well as remove
material from the cylinder is very important. Using a
common spring loaded glaze breaker for honing is not
advised for nicasil cylinders. Polaris recommends
using a rigid hone or arbor honing machine.
Cylinders may be wet or dry honed depending upon
the hone manufacturer’s recommendations. Wet
honing removes more material faster and leaves a
more distinct pattern in the bore.
HONING TO DEGLAZE
A finished cylinder should have a cross-hatch pattern
to ensure piston ring seating and to aid in the retention
of the fuel/oil mixture during initial break in. Hone
cylinder according to hone manufacturer’s
instructions, or these guidelines:
Honing should be done with a
diamond hone. Cylinder could be
damaged if the hone is not hard
enough to scratch the nicasil lining.
S Use a motor speed of approximately
300-500 RPM, run the hone in and
out of the cylinder rapidly until cutting
tension decreases. Remember to
keep the hone drive shaft centered
(or cylinder centered on arbor) and to
bring the stones approximately 1/2″
(1.3 cm) above and below the bore at
the end of each stroke.
S Release the hone at regular intervals
and inspect the bore to determine if
it has been sufficiently deglazed, and
to check for correct cross--hatch.
NOTE: Do not allow cylinder to
heat up during honing.
S After honing has been completed,
inspect cylinder for thinning or
peeling.
If cylinder wear or damage is excessive, it will be
necessary to replace the cylinder. The cylinders are
lined with a nicasil coating and are not repairable.
Hone only enough to deglaze the outer layer of the
cylinder bore.
S
EXAMPLE OF CROSS HATCH PATTERN
IMPORTANT: Clean the Cylinder After Honing
It is very important that the cylinder be thoroughly
cleaned after honing to remove all grit material. Wash
the cylinder in a solvent, then in hot, soapy water. Use
electrical contact cleaner if necessary to clean these
areas. Rinse thoroughly, dry with compressed air,
and oil the bore immediately with Polaris 4 Cycle
Lubricant to prevent the formation of surface rust.

OIL FLOW
This chart describes the flow of oil through the 600/700/800 engine. Beginning in the crankcase sump, the oil
is drawn through an oil galley to the feed side of the oil pump. The oil is then pumped through the oil filter. If the
oil filter is obstructed, a bypass valve contained in the filter allows oil to bypass the filter element. At this point,
the oil is supplied to the main oil galley through a crankcase passage. Oil is then diverted three ways from the
main oil galley, with the first path entering the camshaft bores, onto the rear balance shaft journal and then draining
back into the crankcase sump. The second oil path from the main oil galley feeds the lifter bores and then drains
back to the crankcase sump. The third oil path flows through a crankcase galley to the MAG side crankshaft
journal and also to the front balance shaft journal and onto the crankcase sump. The oil pressure switch is fed
off the main oil galley.

seat reconditioning equipment can also be used.
Keep all valves in order with their respective seat.
1. Clean all accumulated carbon deposits from
combustion chamber and valve seat area with
carbon cleaner and a soft plastic scraper.
NOTE: Valve seat width and point of contact on the
valve face is very important for proper sealing. The
valve must contact the valve seat over the entire
circumference of the seat, and the seat must be the
proper width all the way around. If the seat is uneven,
compression leakage will result. If the seat is too
wide, seat pressure is reduced, causing carbon
accumulation and possible compression loss. If the
seat is too narrow, heat transfer from valve to seat is
reduced. The valve may overheat and warp, resulting
in burnt valves.
IMPORTANT: Do not use a wire brush, metal scraper,
or abrasive cleaners to clean the bottom of the
cylinder head. Extensive damage to the cylinder head
may result. Wear safety glasses during cleaning.

BLEEDING PROCEDURE FOR 4--STROKE COOLING SYSTEMS
Use this procedure when a unit overheats and no apparent leaks in the cooling system are found.
Pump hose by
hand to help
purge system
Note: If the coolant level is LOW in the radiator, or if there
are leaks in the system, the coolant system will not draw
coolant from the reservoir tank.
1. Park Machine on a flat surface. Remove radiator cap and
top off coolant. Leave the cap off of the radiator. Start and idle
machine for 5-10 minutes until steam is visible in the radiator
cap area.
2. Stop the engine and let cool for a few minutes or until a
“glug” is seen at the filler neck or there is a dropping of the
coolant level, indicating that coolant has been pulled into the
system.
Important Tips: Slowly squeezing the hose after the bend
below the filler neck will aid in purging the system of air.
Pump the hose using your hand several times as shown in
the diagram. Elevating the rear of the ATV with a floor jack
(rear tires 4-6, off the ground) also aids the purging of air from
the system.
3. Always add coolant to the radiator first, filling to the top of
the neck to replace air that has been purged from the system.
Fill the reservoir only after you have completely filled the cooling system at the radiator filler neck.
4. Repeat Steps 1 and 2 four or five times or until no more
coolant is pulled into the system.

EFI OPERATION OVERVIEW
The EFI system is designed to provide peak engine
performance with optimum fuel efficiency and lowest
possible emissions. The ignition and injection
functions are electronically controlled, monitored and
continually corrected during operation to maintain
peak performance.
The central component of the system is the Boscht
Engine Control Unit (ECU) which manages system
operation, determining the best combination of fuel
mixture and ignition timing for the current operating
conditions.
An in--tank electric fuel pump is used to move fuel
from the tank through the fuel line and in--line fuel filter.
The in--tank fuel pressure regulator maintains a
system operating pressure of 39 psi and returns any
excess fuel to the tank. At the engine, fuel is fed
through the fuel rail and into the injectors, which inject
into the intake ports. The ECU controls the amount of
fuel by varying the length of time that the injectors are
”on.” This can range from 1.5--8.0 milliseconds
depending on fuel requirements. The controlled
injection of the fuel occurs each crankshaft revolution,
or twice for each 4--stroke cycle. One--half the total
amount of fuel needed for one firing of a cylinder is
injected during each injection. When the intake valve
opens, the fuel/air mixture is drawn into the
combustion chamber, ignited. and burned.
The ECU controls the amount of fuel being injected
and the ignition timing by monitoring the primary
sensor signals for air temperature, barometric air
pressure, engine temperature, speed (RPM), and
throttle position (load). These primary signals are
compared to the programming in the ECU computer
chip, and the ECU adjusts the fuel delivery and
ignition timing to match the values.
During operation the ECU has the ability to re--adjust
temporarily, providing compensation for changes in
overall engine condition and operating environment,
so it will be able to maintain the ideal air/fuel ratio.
During certain operating periods such as cold starts,
warm up, acceleration, etc., a richer air/fuel ratio is
automatically calculated by the ECU.
INITIAL STARTING/PRIMING PROCEDURE
NOTE: The Injection system must be purged of all air
prior to the initial start up, and/or any time the system
has been disassembled.
If the EFI system is completely empty of fuel or has
been disassembled and repaired:
1. Cycle the key switch from “OFF” to “ON” 6 times,
waiting for approximately 3 seconds at each “ON”
cycle to allow the fuel pump to cycle and shut
down.
2. Once step 1 is completed, turn the key switch to
“START” until the engine starts or 5 seconds
seconds has passed.
3. If the engine failed to start, repeat step 1 for 2
more cycles and attempt to start the engine.
If the engine fails to start, a problem may still exist, and
should be diagnosed.
NOTE: Accurate testing of EFI components is
recommended utilizing the Polaris Diagnostic
Software (dealer only).
4.7
FUEL SYSTEM / FUEL INJECTION
ELECTRONIC CONTROL UNIT
(ECU)
The ECU is the brain or central processing computer
of the entire EFI fuel/ignition management system.
During operation, sensors continuously gather data
which is relayed through the wiring harness to input
circuits within the ECU. Signals to the ECU include:
ignition (on/off), crankshaft position and speed
(RPM), throttle position, engine coolant temperature,
air temperature, intake manifold air pressure and
battery voltage. The ECU compares the input signals
to the programmed maps in its memory and
determines the appropriate fuel and spark
requirements for the immediate operating conditions.
The ECU then sends output signals to set the injector
duration and ignition timing.
700 EFI Shown
To prevent engine over--speed and possible failure, a
rev--limiting feature is programmed into the ECU. If
the maximum RPM limit (6500) is exceeded, the ECU
suppresses the injection signals, cutting off the fuel
flow. This process repeats it self in rapid succession,
limiting operation to the preset maximum.
Sportsman 700 / 800 EFI Rpm Limit:

Park: 6500
Soft limit -- Timing Suppression occurs
High: None
Low: 6300
Neutral: 6300
Reverse: 6300
Park: 6300
ECU SERVICE
Never attempt to disassemble the ECU. It is sealed to
prevent damage to internal components. Warranty is
void if the case is opened or tampered with in any way.
During operation, the ECU continually performs a
diagnostic check of itself, each of the sensors, and
system performance. If a fault is detected, the ECU
turns on the Malfunction Indicator Light (MIL) (Check
Engine Light) on the speedometer and stores the fault
code in its fault memory.
Depending on the
significance or severity of the fault, normal operation
may continue, or ”Fail--Safe” operation (slowed
speed, richer running) may be initiated. A technician
can access the stored fault code using a ”blink code”
diagnosis flashed out through the Instrument cluster.
The ECU requires a minimum of 7.0 volts to operate.
The memory in the ECU is operational the moment
the battery cables are connected.
4.8
All operating and control functions within the ECU are
pre--set. No internal servicing or readjustment may be
performed. If a problem is encountered, and you
determine the ECU to be faulty, contact the Polaris
Service Department for specific handling instructions.
Do not replace the ECU without factory authorization.
The relationship between the ECU and the throttle
position sensor (TPS) is very critical to proper system
operation. If the TPS is faulty, or the mounting position
of the TPS is altered, the TPS must be re--initialized.
For the purpose of troubleshooting, a known--good
ECU from another Polaris ATV EFI may be used
without system or engine component damage.
ECU REPLACEMENT
1. Remove the 2 retaining screws holding the ECU.
2. With the Ignition turned off, disconnect the wire
harness from the ECU.
3. To install, reverse the procedures, reapply a small
amount of dielectric grease to the connector if
desired. Tighten screws to 10 in. lbs (1.1 Nm).
FUEL SYSTEM / FUEL INJECTION
FUEL PUMP ASSEMBLY
NOTE: 800 EFI fuel connections are quick--connect
couplings vs 700 EFI connections.
An electric fuel pump assembly is used to transfer fuel
to the EFI system from inside the fuel tank. This
assembly includes the fuel pump, regulator and fuel
gauge sender. The pump is rated for a minimum
output of 25 liters per hour at 39 psi and has a
non--serviceable internal 30--micron filter. In addition,
the pump has a replaceable 10--micron filter attached
to the pump outlet, which is located under the strut
mount.
Fuel pump is not replaceable.
Picture is for reference only.
The fuel pump/tank assembly is non--serviceable and
must be replaced if determined to be faulty. If a fuel
delivery problem is suspected, make certain the filters
are not plugged, that the pump is being activated
through the ECU, all electrical connections are
properly secured, the fuses are good, and a minimum
of 7.0 volts is being supplied. If during starting the
battery voltage drops below 7.0 volts, a reduction of
fuel pressure may occur resulting in a lean starting
condition. If required, testing of the fuel pump and
circuitry may be conducted.
CAUTION:
Check the fuel test valve for any possible fuel
seepage after performing any tests or
procedures. Fuel is extremely flammable and
may cause severe burns, injury, or death. Do not
use any device that produces a flame or electrical
devices that may spark around fuel or fuel vapors.

When the key switch is turned to ”ON”, the ECU
activates the fuel pump, which pressurizes the
system for start--up.
The ECU switches off the pump preventing the
continued delivery of fuel in these instances:
If the key switch is not promptly
turned to the ”start” position
G if the engine fails to start, or
G if the engine is stopped with the key
switch ”on” (as in the case of an
accident),
In these situations, the “check engine” light will go on,
but will turn off after 4 cranking revolutions if system
function is OK. Once the engine is running, the fuel
pump remains on.

1. Remove the fuel test valve cap. Connect the
pressure hose of the Polaris pressure tester (PN
PU--43506) to the test valve on the fuel rail. Route
the clear hose into a portable gasoline container
or the equipment fuel tank.
NOTE: FUEL GAUGE SENDER TEST -- To test fuel
gauge sender function, refer to Chapter 10 in this
service manual.

2. Turn on the key switch to activate the pump and
check the system pressure on the gauge. If
system pressure of 39 psi ± 3 is observed, the
ignition switch, ECU, fuel pump, and pressure
regulator are working properly. Turn the key
switch off and depress the valve button on the
tester to relieve the system pressure.
G If the pressure is too high or too low,
replace the fuel pump assembly.
3. If the pump did not activate (step 2), disconnect
the plug from the fuel pump. Connect a DC
voltmeter across terminals ’A’ and ’C’ in the plug,
turn on the key switch and observe if a minimum
of 7 volts is present. If voltage is between 7 and
14, turn key switch off and connect an ohmmeter
between the terminals ’A’ and ’C’ on the pump to
check for continuity.
G If there was no continuity between
the pump terminals, replace the fuel
pump/tank assembly.
G If the voltage was below 7 Vdc, test the
battery, ignition switch, wiring harness,
Load--shed/Relay, and ECU.
4. If voltage at the plug was good, and there was
continuity across the pump terminals, reconnect
the plug to the pump, making sure you have good,
clean connections. Turn on the key switch and
listen for the pump to activate.
G If the pump starts, repeat steps 1 and
2 to verify correct pressure.
G If the pump still does not operate,
check for correct ECU operation by
plugging in a known--good ECU.
G If the pump still does not operate,
replace the pump/tank assembly.

FUEL PRESSURE
REGULATOR
The fuel pressure regulator maintains the required
operating system pressure of 39 psi ± 3psi. A
rubber--fiber diaphragm divides the regulator into two
separate sections--, the fuel chamber and the pressure
regulating chamber. The pressure regulating spring
presses against the valve holder (part of the
diaphragm), pressing the valve against the valve seat.
The combination of atmospheric pressure and
regulating spring tension equals the desired operating
pressure. Any time the fuel pressure against the bottom
of the diaphragm exceeds the desired (top) pressure,
the valve opens, relieving the excess pressure,
returning the excess fuel back to the tank.

FUEL INJECTORS
NOTE: 800 EFI fuel connections are quick--connect
couplings vs 700 EFI connections.
The fuel injectors mount into the intake manifold, and
the fuel rail attaches to them at the top end.
Replaceable O--Rings on both ends of the injector
prevent external fuel leakage and also insulate it from
heat and vibration.
FUEL FILTERS
NOTE: 800 EFI fuel connections are quick--connect
couplings vs 700 EFI connections.
EFI Engines use a non--serviceable, high--volume,
high--pressure, 30--micron internal fuel pump filter
and a replaceable 10--micron, in--line fuel filter.
Injector

FUEL FILTER SERVICE
In line filter replacement is recommended every 2
years of operation or more frequently under extremely
dusty, dirty conditions. Use only the specified filter,
and install it according to the directional arrows. DO
NOT use an aftermarket filter, as operating
performance and safety can be affected.
FUEL FILTER REPLACEMENT
To replace the filter:
1. Relieve system pressure through the test valve in
the fuel rail before servicing.
2. Loosen clamps and slide hose off the filter ends.
3. Install new filter with arrow pointing to the fuel line
connected to the injector rail.
NOTE: When replacing the fuel filter, wet the interior
of the new filter with gasoline before installation to
ensure high pump pressure doesn’t tear the filtering
material.
4.12
When the key switch is on, the fuel rail is pressurized,
and voltage is present at the injector. At the proper
instant, the ECU completes the ground circuit,
energizing the injector. The valve needle in the
injector is opened electromagnetically, and the
pressure in the fuel rail forces fuel down through the
inside. The ”director plate” at the tip of the injector (see
inset) contains a series of calibrated openings which
directs the fuel into the intake port in a cone--shaped
spray pattern.
The injector is opened and closed once for each
crankshaft revolution, however only one--half the total
amount of fuel needed for one firing is injected during
each opening. The amount of fuel injected is
controlled by the ECU and determined by the length
of time the valve needle is held open, also referred to
as the .’injection duration” or ”pulse width”. It may vary
in length from 1.5--8 milliseconds depending on the
speed and load requirements of the engine.
FUEL SYSTEM / FUEL INJECTION
FUEL INJECTOR SERVICE
FUEL INJECTOR REPLACEMENT
Injector problems typically fall into three general
categories-- electrical, dirty/clogged, or leakage. An
electrical problem usually causes one or both of the
injectors to stop functioning. Several methods may be
used to check if the injectors are operating.
1. Engine must be cool. Depressurize fuel system
through test valve in fuel rail.
2. Remove the front fender assembly and fuel tank.
3. Thoroughly clean the area around and including
the throttle body/manifold and the injectors.
4. Disconnect the fuel injector harness(s) at the
ECU.
5. Remove the fuel rail mounting screw and carefully
loosen / pull the rail away from the injectors.
6. Reverse the procedures to install the new
injector(s) and reassemble. Use new O--rings any
time an injector is removed (new replacement
injectors include new O--rings). Lubricate O--rings
lightly with oil to aid installation. Torque the fuel rail
mounting screw to 16--20 ft. lbs. (22.6--27 Nm).
With the engine running at idle, feel
for operational vibration, indicating
that they are opening and closing.
G When
temperatures
prohibit
touching, listen for a buzzing or
clicking sound with a screwdriver or
mechanic’s stethoscope.
G Disconnect the electrical connector
from an injector and listen for a
change in idle performance (only
running on one cylinder) or a change
in injector noise or vibration.
NOTE: Do not apply voltage directly to the fuel
injector(s). Excessive voltage will burn out the
injector(s). Do not ground the injector(s) with the
ignition “on.” lnjector(s) will open/turn on if relay is
energized.
G
If an injector is not operating, it can indicate either a
bad injector, or a wiring/electrical connection problem.
Check as follows:
CRANKSHAFT POSITION
SENSOR (CPS)
The engine speed sensor is essential to engine
operation, constantly monitoring the rotational speed
(RPM) of the crankshaft.
Injector leakage is very unlikely, but in rare instances
it can be internal (past the tip of the valve needle), or
external (weeping around the injector body). The loss
of system pressure from the leakage can cause hot
restart problems and longer start--up times.
Injector problems due to dirt or clogging are unlikely
due to the design of the injectors, the high fuel
pressure, the use of filters and the detergent additives
in the gasoline. Symptoms that could be caused by
dirty/clogged
injectors
include
rough
idle,
hesitation/stumble during acceleration, or triggering
of fault codes related to fuel delivery. Injector clogging
is usually caused by a buildup of deposits on the
deflector plate, restricting the flow of fuel and resulting
in a poor spray pattern. Some contributing factors to
injector clogging include; dirty air filters, higher than
normal operating temperatures, short operating
intervals and dirty, incorrect, or poor quality fuel.
Cleaning of clogged injectors is not recommended;
they should be replaced. Additives and higher grades
of fuel can be used as a preventative measure if
clogging has been a problem.
Crankshaft Position Sensor
A ferromagnetic 60--tooth ring gear with two
consecutive teeth missing is mounted on the flywheel.
The inductive speed sensor is mounted 1.0 ± 0.26 mm
(0.059 ± 0.010 in.) away from the ring gear. During
rotation, an AC pulse is created within the sensor for
each passing tooth. The ECU calculates engine
speed from the time interval between the consecutive
pulses. The two--tooth gap creates an “interrupt” input
signal, corresponding to specific crankshaft position
for PTO cylinder. This signal serves as a reference for
the control of ignition timing by the ECU.
Synchronization of the CPS and crankshaft position
takes place during the first two revolutions each time
the engine is started. This sensor must be properly
connected at all times. If the sensor fails or becomes
disconnected for any reason, the engine will quit
running.
4.13
FUEL SYSTEM / FUEL INJECTION
CRANKSHAFT POSITION SENSOR TEST
The crankshaft position sensor is a sealed,
non--serviceable assembly. If fault code diagnosis
indicates a problem within this area, test and correct
as follows:
1. Disconnect main harness connector from ECU.
2. Connect an ohmmeter between the pin terminals.
A resistance value of 560 Ω ± 10% at room
temperature (20_ C, 68_F) should be obtained. If
resistance is correct, check the mounting, air gap,
toothed ring gear (damage, runout, etc.), and
flywheel key.
3. Disconnect speed sensor connector from wiring
harness. (the connector with one heavy black
lead) Viewing the connector with dual aligning
rails on top, test resistance between the
terminals. A reading of 560 Ω ± 10% should again
be obtained.
NOTE: If the resistance is incorrect, remove the
screw securing the sensor to the mounting bracket
and replace the sensor. If the resistance in step 2 was
incorrect, but the resistance of the sensor alone was
correct, test the main harness circuit between the
sensor connector terminals and the corresponding pin
terminals in the main connector. Correct any
observed problem, reconnect the sensor, and perform
step 2 again.

1. Disconnect sensor harness connector.
2. Using a 6mm hex wrench, remove the retaining

TEMPERATURE and
BAROMETRIC AIR
PRESSURE SENSOR (T--BAP)
Mounted on the throttle body intake, the temperature
and barometric air pressure sensor (T--BAP)
performs two functions in one unit.
Air passing through the intake is measured by the
T--BAP and relayed to the ECU. These signals,
comprised of separate air temperature and
barometric air pressure readings, are processed by
the ECU and compared to it’s programming for
determining the fuel and ignition requirements during
operation.
TEMPERATURE AND BAROMETRIC AIR
PRESSURE SENSOR TEST
The temperature and barometric air pressure sensor
(T--BAP) is a non--serviceable item. If it is faulty, it must
be replaced. This sensor requires a 5 Vdc input to
operate, therefore the T--BAP sensor should only be
tested using the Polaris Diagnostic Software (dealer
only). Refer to the EFI Diagnostic Software Manual for

FUEL SYSTEM / FUEL INJECTION
THROTTLE POSITION
SENSOR (TPS)
The throttle position sensor (TPS) is used to indicate
throttle plate angle to the ECU.
Mounted on the throttle body and operated directly off
the end of the throttle shaft, the TPS works like a
rheostat, varying the voltage signal to the ECU in
direct correlation to the angle of the throttle plate. This
signal is processed by the ECU and compared to the
internal pre--programmed maps to determine the
required fuel and ignition settings for the amount of
engine load.
NOTE: The correct position of the TPS is
established and set at the factory. Do not loosen
the TPS or alter the mounting position. If the TPS
is repositioned, replaced or loosened it must be
recalibrated.
THROTTLE POSITION SENSOR TEST
The throttle position sensor (TPS) is a non--serviceable
item. If it is faulty, it must be replaced. It can be tested
using the following method:

INITIALIZATION
The correct position of the TPS is established and

TPS was repositioned, replaced or loosened.
This set procedure can be accomplished with the
throttle body attached to the engine. This
procedure is meant to allow the TPS flow and idle
offset voltage to be correctly set without the use of
a flow bench. No steps can be eliminated.
Step 1
Establishing zero offset voltage: This step is
crucial as it sets the TPS position using a fixed
physical stop. This will insure that the correct offset
voltage is reached once the correct throttle body flow
is set.

PVT OPERATION OVERVIEW
WARNING
All PVT maintenance or repairs should be
performed only by a certified Polaris Master Service
Dealer (MSD) technician who has received the proper
training and understands the procedures outlined in
this manual. Because of the critical nature and
precision balance incorporated into the PVT
components, it is absolutely essential that no
disassembly or repair be made without factory
authorized special tools and service procedures.
The Polaris Variable Transmission (PVT) consists of
three major assemblies: 1) The Drive Clutch; 2) The
Driven Clutch; and 3) The Drive Belt. The internal
components of the drive clutch and driven clutch
control engagement (initial vehicle movement), clutch
upshift and backshift. During the development of a
Polaris ATV, the PVT system is matched first to the
engine power curve; then to average riding conditions
and the vehicle’s intended usage.
Therefore,
modifications or variations of components at random
are never recommended. Proper clutch setup and
careful inspection of existing components must be the
primary objective when troubleshooting and tuning.
DRIVE CLUTCH OPERATION
Drive clutches primarily sense engine RPM. The two
major components which control its shifting function
are the shift weights and the coil spring. Whenever
engine RPM is increased, centrifugal force is created,
causing the shift weights to push against rollers on the
moveable sheave, which is held open by coil spring
preload. When this force becomes higher than the
preload in the spring, the outer sheave moves inward
and contacts the drive belt. This motion pinches the
drive belt between the spinning sheaves and causes
it to rotate, which in turn rotates the driven clutch.
At lower RPM, the drive belt rotates low in the drive
clutch sheaves.
As engine RPM increases,
centrifugal force causes the drive belt to be forced
upward on drive clutch sheaves.
DRIVEN CLUTCH OPERATION
Driven clutches primarily sense torque, opening and
closing according to the forces applied to it from the
drive belt and the transmission input shaft. If the
torque resistance at the transmission input shaft is
greater than the load from the drive belt, the drive belt
is kept at the outer diameter of the driven clutch
sheaves.
CLUTCH
DRIVEN CLUTCH OPERATION CONT’D
As engine RPM and horsepower increase, the load
from the drive belt increases, resulting in the belt
rotating up toward the outer diameter of the drive
clutch sheaves and downward into the sheaves of the
driven clutch. This action, which increases the driven
clutch speed, is called upshifting.
Should the throttle setting remain the same and the
vehicle is subjected to a heavier load, the drive belt
rotates back up toward the outer diameter of the
driven clutch and downward into the sheaves of the
drive clutch. This action, which decreases the driven
clutch speed, is called backshifting.
In situations where loads vary (such as uphill and
downhill) and throttle settings are constant, the drive
and driven clutches are continually shifting to maintain
optimum engine RPM. At full throttle a perfectly
matched PVT system should hold engine RPM at the
peak of the power curve. This RPM should be
maintained during clutch upshift and backshift. In this
respect, the PVT system is similar to a power
governor. Rather than vary throttle position, as a
conventional governor does, the PVT system
changes engine load requirements by either
upshifting or backshifting.
PVT
MAINTENANCE/INSPECTION
Under normal operation the PVT system will provide
years of trouble free operation. Periodic inspection
and maintenance is required to keep the system
operating at peak performance. The following list of
items should be inspected and maintained to ensure
maximum performance and service life of PVT
components. Refer to the troubleshooting checklist at
the end of this chapter for more information.
1. Drive to Driven Clutch Offset, Belt Width. See
Page-6.16--6.18
2. Drive and Driven Clutch Rollers and
Bushings, Drive Clutch Shift Weights and
Pins, Drive Clutch Spider Rollers and Roller
Pins, Drive and Driven Clutch Springs. See
Pages 6.11-6.12
3. Sheave Faces. Clean and inspect for wear.
4. PVT System Sealing. Refer to appropriate
illustrations and photos. The PVT system is air
cooled by fins on the drive clutch stationary
sheave. The fins create a low pressure area in the
crankcase casting, drawing air into the system
through an intake duct. The opening for this
intake duct is located at a high point on the vehicle
(location varies by model). The intake duct draws
fresh air through a vented cover. All connecting
air ducts, as well as the inner and outer covers,
must be properly sealed to ensure clean air is
being used for cooling the PVT system. This also
will prevent water and other contaminants from
entering the PVT area. A sealed PVT is
especially critical on units subjected to frequent
water forging.
PVT DRYING
Special Tool NOTE: If operating the ATV through
water, be sure to check the PVT cover and other ATV
components for water ingestion. The ATV should be
checked immediately. Refer to Owner’s Manual for
Safe Riding Tips.
PVT Drain Plug
To drain any water that may be trapped inside the PVT
cover, simply remove the PVT drain plug and O--ring
located on the bottom of the PVT cover and let the
water drain out. The PVT drain plug is shown below.
To further expel water in the PVT cover and to dry out
the PVT system, shift the transmission to neutral and
rev engine slightly to expel the moisture. This will also
air-dry the belt and clutches. Allow engine RPM to
settle to idle speed, shift transmission to lowest
available range and test for belt slippage. Repeat as
needed. Operate ATV in lowest available range for a
short period of time until PVT system is dry.

PVT OVERHEATING/DIAGNOSIS
During routine maintenance or whenever PVT system overheating is evident, it’s important to check the inlet
and outlet ducting for obstructions. Obstructions to air flow through the ducts will significantly increase PVT
system operating temperatures. The ATV should be operated in LOW RANGE when pulling or plowing heavy
loads, or if extended low speed operation is anticipated.
GENERAL RANGE OPERATION
GUIDELINES:
Low Range: Heavy pulling, basic operational speeds less
than 7 MPH, riding through rough terrain (swamps, mountains,
etc..), low ground speeds.
High Range: High ground speeds, speeds above 7 MPH.

DRIVE CLUTCH SPRING SPECIFICATIONS
1. Controls clutch engagement
RPM. The springs which have a
higher rate when the clutch is in
neutral will increase clutch
engagement RPM.
2. Controls the rate at which the
drive belt moves upward in the
drive clutch sheaves. This is
referred to as drive clutch upshift.
The drive clutch spring is one of the
most critical components of the PVT
system. It is also one of the easiest to
service. Due to the severe stress the
coil spring is subject to during
operation, it should always be
inspected for tolerance limits during
any clutch diagnosis or repair.
There are other components which
control upshift, but the spring is one of
the primary components in insuring
optimum performance. It is very
important that the spring is of correct
design and is in good condition.
CAUTION: Never shim a drive clutch
spring to increase its compression
rate. This may result in complete
stacking of the coils and subsequent
clutch component failure.

6. Inspect belt for hour glassing (extreme circular
wear in at least one spot and on both sides of the
belt). Hour glassing occurs when the drive train
does not move and the drive clutch engages the
belt continuously in one spot.
7. Measure belt length with a tape measure around
the outer circumference of the belt. Belts which
measure longer than nominal length may require
driven shimming or engine adjustment for a
longer center distance to obtain proper belt
deflection. Belts which measure shorter than
nominal length may require driven shimming or a
shorter center distance. Remember, proper belt
deflection is the desired goal -- not a specific
center distance.
8. Replace belt if worn past the service limit. Belts
with thin spots, burn marks, etc., should be
replaced to eliminate noise, vibration, or erratic
PVT operation. See Troubleshooting Chart at the
end of this chapter for possible causes.

Special Tool NOTE:Be sure to position belt so part
number is easily read. Verfiy new belt is seated
properly in the clutches before operating the ATV.
1. Loop belt over drive and over top of driven
sheave.
2. While pushing down on top of belt, turn the back
or moveable driven sheave clockwise.
3. The belt then should be able to be pushed down
into and between the sheaves.
4. Install clutch cover temporarily. Verify engine is in

DISASSEMBLY/INSPECTION EBS Driven Clutch Operation
1. Remove driven clutch from the transmission input
shaft. Do not attempt disassembly of the driven
clutch from the outside snap ring. The driven
clutch must be disassembled from the helix side.
This EBS driven clutch provides the same engine
braking abilities as the earlier EBS driven clutch.

Belt Rotation
Do not disassemble from this side
2. It is important to mark the position of the shaft,
cam cover, and sheave before disassembly or
use the “X”s on the components for reference.
This will aid in reassembly and helps to maintain
clutch balance after reassembly.
Mark Components Before Disassembly
Drive
When the ATV is moving downhill the drive train turns
the driven clutch, belt, and one way clutch in the
direction of engine rotation. When the one--way
clutch (see exploded view of drive clutch) exceeds the
drive clutch rotational speed, the one--way clutch
locks to the drive clutch shaft and engine braking
occurs. Essentially the driven clutch has become the
“driving” clutch. The spider assembly with the two
rollers, that is fixed to the transmission shaft rotates
in the pockets of the sheave, allowing the stationary
sheave to rotate with the moveable sheave as the
rollers move to the other side of the ramp, providing
instant EBS braking. Engine braking (EBS) continues
until the drive clutch speed exceeds the one--way
clutch speed, or until the throttle is applied and the
engine reaches clutch engagement speed, lifting the
belt off of the one--way clutch.
3. Remove the four torx screws that secure the cam
assembly (helix) using a T25 torx.
CAUTION: The driven clutch must be
disassembled from the helix end to reduce spring
pressure. Review all information below before
proceeding.

DIAGNOSIS
Check for wear bands
ILL. 1
Possible
Wear Ring on
Armature Plate
Symptom: AWD Will Not Engage.
1. Check the gearcase coil resistance. To test the
gearcase coil resistance, use the coil harness
(Grey & Brown/White). The gearcase coils should
measure between 22.8 ohms and 25.2 ohms.
2. Check the minimum battery voltage at the wire
(Grey & Brown/White) that feeds the hub coil wire.
There should be a minimum of 11.80--12.0 Volts
present for proper operation.
OK Condition
Bad Condition
(Wear from Coil
On Armature Plate)
3. Inspect the armature plate for a consistent wear
pattern. There should one or two distinct wear
bands (one band inside the other). If only one
7.16
4. Check to make sure the coil is seated in the
U--shaped insert that is pressed into the gearcase
cover. The top of the coil should be seated below
the U--shaped insert. The U--shaped insert
controls the pole gap. If the top of the coil is above
the surface of the U--shaped insert it raises the
armature plate, thereby increasing pole gap. If
the pole gap increases the coil will not be strong
enough to engage the AWD system. If this is the
cause order a new Plate Cover Assembly (PN

The complete driveshaft and joint
should be handled by getting hold of
the interconnecting shaft to avoid
disassembly or potential damage to
the driveshaft joints.
Over-angling of joints beyond their
capacity could result in boot or joint
damage.
Make sure surface-ground areas
and splines of shaft are protected
during handling to avoid damage.
Do not allow boots to come into
contact with sharp edges or hot
engine and exhaust components.
The driveshaft is not to be used as a
lever arm to position other
suspension components.
Never use a hammer or sharp tools
to remove or to install boot clamps.
Be sure joints are thoroughly clean
and that the proper amount and type
of grease is used to refill when joint
boots are replaced and when joints
are cleaned. Refer to text for grease

BRAKE SYSTEM SERVICE
NOTES
Polaris disc brake systems are light weight, low
maintenance and perform well in the conditions ATVs
routinely encounter. However, there are a few things
to remember when replacing disc brake pads or
performing brake system service to ensure proper
system function and maximum pad service life.
S
S
S
S
S
S
S
Perform
a
brake
burnishing
procedure after installing new pads
to maximize service life.
Optional pads are available to suit
conditions in your area. Select a pad
to fit riding style and environment.
Do not over-fill the master cylinder
fluid reservoir.
Make sure the brake lever and pedal
returns freely and completely.
Adjust stop pin on front caliper after
pad service.
Check and adjust master cylinder
reservoir fluid level after pad service.
Make sure atmospheric vent on
reservoir is unobstructed.
S
S
S
Test for brake drag after any brake
system service and investigate
cause if brake drag is evident.
Make sure caliper moves freely on
guide pins (where applicable).
Inspect caliper piston seals for
foreign material that could prevent
caliper pistons from returning freely.
CAUTION:
Use only DOT 3 brake fluid as an
assembly aid for all procedures described in this chapter to
prevent brake system contamination. DO NOT USE
LUBRICANTS OF ANY KIND FOR ASSEMBLY, AS THEIR
USE CAN CAUSE RUBBER COMPONENTS TO SWELL.
BRAKE NOISE
TROUBLESHOOTING
Dirt or dust buildup on the brake pads and disc is the
most common cause of brake noise (squeal caused
by vibration). If cleaning does not reduce the
occurrence of brake noise, Permatext Disc Brake
Quiet (PN 2872113) can be applied to the back of the
pads. Follow directions on the package. This will
keep pads in contact with caliper piston(s) to reduce
the chance of squeaks caused by dirt or dust.

OPERATION OVERVIEW
Check wheel and hub

Replace disc
Inspect and repair as

If noise does not

applied check other
sources. Inspect and
repair as necessary
Change to a softer or
harder pad
When the hand activated brake lever (A) is applied it
contacts piston (B) within the master cylinder. As the
master cylinder piston moves inward it closes a small
opening (compensating port C) within the cylinder and
starts to build pressure within the brake system. As
the pressure within the system is increased, the piston
(D) located in the brake caliper moves outward and
applies pressure to the brake pad. This pad contacts
the brake disc and moves the caliper in its floating
bracket, pulling the stationary side pad into the brake
disc. The resulting friction reduces brake disc and
vehicle speed. As the lever pressure is increased, the
braking affect is also increased.
The friction applied to the brake pads will cause the
pads to wear. As these pads wear, the piston within
the caliper moves further outward and becomes self
adjusting. Fluid from the reservoir fills the additional
area created when the caliper piston moves outward.
Brake fluid level is critical to proper system operation.
Too little fluid will allow air to enter the system and
cause the brakes to feel spongy. Too much fluid could
cause brakes to drag due to fluid expansion.
Located within the master cylinder is the
compensating port (C) which is opened and closed by
the master cylinder piston assembly. The port is open
9.6
BRAKES
when the lever is released and the master cylinder
piston is outward. As the temperature within the
hydraulic system changes, this port compensates for
fluid expansion (heated fluid) or contraction (cooled
fluid). During system service, be sure this port is
open. Due to the high temperatures created within the
system during heavy braking, it is very important that
the master cylinder reservoir have adequate space to
allow for fluid expansion.
Never overfill the
reservoir! Fill to 1/4″ - 5/16″ (.64 - .80 cm) from top
of the cylinder.
This system also incorporates a diaphragm (E) as part
of the cover gasket; and a vent port (F) located
between the gasket and the cover. The combination
diaphragm and vent allow for the air above the fluid to
equalize pressure as the fluid expands or contracts.
Make sure the vent is open and allowed to function.
If the reservoir is over filled or the diaphragm vent is
plugged the expanding fluid may build pressure in the
brake system leading to brake failure.
When servicing Polaris ATV brake systems, use only
Polaris DOT 3 Brake Fluid (PN 2870990).
WARNING: Once a bottle is opened, use what is
necessary and discard the rest in accordance with
local laws. Do not store or use a partial bottle of brake
fluid. Brake fluid is hygroscopic, meaning it rapidly
absorbs moisture.
This causes the boiling
temperature of the brake fluid to drop, which can lead
to brake fade and the possible loss of control.
HYDRAULIC
CALIPER BLEEDING
The front calipers a single piston conventional design.
The rear caliper piston is a “T”-shaped, which allows
both hand and foot brake to use the same caliper
piston, but remain separated by seals. The hand
brake system applies hydraulic pressure to both front
calipers and only the outer diameter of the rear caliper
pistons. The auxiliary (foot) brake applies pressure to
the inner portion of the rear caliper pistons. Because
the hand and foot brake hydraulic systems are
separate, there are also two bleed screws -- one for
the outer fluid chamber (hand brake), and one for the
inner fluid chamber (foot brake). The basic procedure
for bleeding the brake system is the same as outlined
on page 9.7 - 9.8, however, each system must be bled
separately.
NOTE: Uppermost (inner) bleed screw and brake line
(A) is for hand brake system. Lower (outer) bleed screw
and brake line (B) is for auxiliary (foot) brake system.

OVERVIEW
1. Odometer/Tachometer/Trip meter/Hour Meter
* Odometer records the miles traveled by the ATV.
*Tachometer displays engine RPM. This feature will
also display with the vehicle in motion NOTE: Small
RPM fluctuations from day to day are normal because
of changes in humidity, temperature, and elevation.
*Trip meter records the miles traveled by the ATV if
reset before each trip or total miles to 999. To reset
the trip meter, select the trip meter mode. Press and
hold the mode button (override button) until the total
changes to 0. NOTE: In the Rider Information Center,
the trip meter display contains a decimal point, but the
odometer displays without a decimal point.
*Hour Meter logs the total hours the engine has been
in operation.

Ill.2
Introduction
Refer to Illustration 1:
The Polaris ATV Instrument Cluster is powered by
battery voltage (12 VDC) and requires inputs from the
engine RPM, transmission gear, and wheel speed
sensor for proper operation. Two harnesses plug into
the cluster head; one from the right front wheel speed
sensor, and one from the vehicle main harness. A
non-serviceable internal memory battery maintains
odometer and hour meter data when the machine is
not running. The illumination lamp inside the gauge
is non-serviceable and is designed to last for the life
of the unit. (A) The speedometer needle indicates
speed from an electronic wheel speed sensor located
on the right front brake caliper bracket and the needle
also flashes during a warning condition.
The
speedometer needle indicates speed in MPH and
KPH. NOTE: A flashing needle could indicate a
hot engine, low battery warning, or the No. 10 Pin
could be grounded. (B) The speedometer features
numbers in Mile Per Hour (MPH) and Kilometers Per
Hour (KPH). (C) The Rider Information Center
performs a number of functions (See Illustration 2):
2.Programmable Service Interval/Diagnostic
Mode
*Service Interval -- The purpose of the
programmable service interval is to provide the
consumer and the dealer with a convenient way to
schedule routine maintenance. When the ATV leaves
the factory, this feature is set at “50 hours”. When the
first 50 hours of engine operation are finished the
wrench icon will flash for 10 seconds each time the
ATV is started as a reminder that ATV maintenance
is due. NOTE: To reset the Service Interval, follow the
directions on the on Page 10.5, “Setting New Service
Interval”.
3. Check Engine Warning Indicator
The word HOT will display alpha numerically when the
engine is overheating. Do not continue to operate the
ATV if this warning appears. Refer to Chapter 3
“Cooling System Troubleshooting” for help with
diagnosis of overheating.
4. High/Low Battery Voltage
This warning usually indicates that the ATV is being
operated at an RPM too low to keep the battery
charged. A low battery warning may also occur under
normal operation if the machine is at idle and high
electrical load (lights, cooling fan, accessories) is
applied. Driving at a higher RPM or connecting a
battery charger will usually clear the warning.

5. Engine Hour Display Indicator
Displays number of hours of engine operation.
Screen 1: The first screen indicates battery voltage.
Refer to Ill. 2.
6. AWD Indicator
Illuminates when the electrical portion of the AWD
system is enabled.
7. Gear Indicator
Specifies what position the shift lever and
transmission are in. This area is blank if a fault occurs.
8. Mode Indicator
Indicates which modes are being utilized.
9. Fuel Gauge
The segments of the fuel gauge indicate the level of
fuel in the fuel tank. When the last segment clears, a
low fuel warning is activated. All related icons will
flash, “FUEL” will display in the LCD, and the
speedometer needle will blink. If riding, be sure to
refuel immediately.

Screen 2: Tachometer (Ill. 3) indicates engine rpm.
Ill.3
Blink When Low on Fuel
Screen 3: AWD diagnostic screen. This screen
indicates whether or not current is flowing through the
AWD coil on models with switchable AWD.
DIAGNOSTIC MODE
NOTE: This gauge features auto shut--off protection
if the voltage on the DC bus is excessive. This is
usually the result of an open battery condition, and the
gauge is designed to survive such an event.
NOTE: If the gauge will not indicate what gear it is in
and will not allow AWD operation, AWD can still be
enabled by holding in the mode/override button.
To enter the diagnostics mode:
1. Turn the key switch off and wait 10 seconds.
2. Set the park brake and shift the transmission to
neutral.
3. Hold the mode/reverse override button as you
turn the key switch on.
4. Release the switch as soon as the display is
activated.
Use the mode/reverse override button to toggle
through the diagnostic screens.
NOTE: The initial screen display refers to the
software version installed on your ATV.
This
information is only displayed briefly.

Screen 5: Programmable service interval. The
purpose of the programmable service interval is to
provide the consumer and dealer with a convenient
reminder for routine maintenance. When the ATV
leaves the factory, this feature is set at 50 hours.
Once the service interval mode is set with the hours
when service is due, the hours of actual engine
operation are subtracted from the set hours until 0 is
reached. When the counter reaches 0, the wrench
icon will flash quickly for 10 seconds each time the
vehicle is started as a reminder that the periodic
maintenance is due.

SETTING A NEW SERVICE INTERVAL:
Setting Service Interval After Countdown (zero):
1. While in the service interval mode, press and hold
the mode/override button until the wrench icon
flashes. When it begins to flash, release the button.
2. The setting will increase by one hour each time the

1. Remove the three screws that secure the
headlight pod cover and disconnect the wire
connectors from the instrument cluster.
1. Spray a soap and water mixture onto the outer
surface area of the instrument cluster. This will
help the instrument cluster slide into the pod
assembly more easily.
2. Push the instrument cluster out from the backside
of the pod, while securely holding the pod.
2. Be sure the rubber grommet inside the pod is fully
installed and that the indexing key is in the
headlight pod keyway.

The coolant temperature sensor can be tested using an
ohmeter or voltmeter.
1. With the engine and temperature sensor at room
temperature (68° F = 20° C), disconnect the
harness connector.
2. With the meter in the ohms mode, place the meter
leads onto the sensor contacts. One lead on
Yellow wire and one lead on the Violet wire.
3. Use the table Temperature / Resistance table to
determine if the sensor needs to be replaced.
Temperature °F (°C)

NOTE: If the coolant temperature sensor or circuit
malfunctions the radiator fan will default to ’ON’.
NOTE: The fan may not function or operation may be
delayed if coolant level is low or if air is trapped in the
cooling system. Be sure cooling system is full and
purged of air. Refer to Maintenance Chapter 2 for
cooling system information.
FAN CONTROL CIRCUIT
OPERATION / TESTING
Power is supplied to the fan via the Orange/Black wire
when the relay is ON. The ground path for the fan
motor is through the Brown harness wire. Refer to
page 10.20 for more information on Fan Relay
functions.
CAUTION: Keep hands away from fan blades
during operation. Serious personal injury could
result.
NOTE: The fan may not function or operation may be
delayed if coolant level is low or if air is trapped in the
cooling system. Be sure cooling system is full and
purged of air. Refer to Maintenance Chapter 2 for
cooling system information.

BYPASS TEST
1. Disconnect harness from coolant temperature
sensor on engine.
10.14
2. With the ATV in “Park” and with the parking brake
on, turn the ignition key (and engine stop switch)
“ON”. The fan should start running.
3. If the fan does not run or runs slowly, check the fan
motor wiring, ground, motor condition and
mechanical relay for proper operation (refer to
’Fan Motor Current Draw’ this section). Repair or
replace as necessary. If the fan runs with the
sensor harness disconnected, but will not turn on
when the engine is hot, check the coolant
temperature sensor and connector terminals.
FAN MOTOR CURRENT DRAW
A current draw test will provide a good indication of fan
motor condition. A worn or damaged fan motor will
draw more current, which causes a reduction in blade
speed and reduced cooling.

ELECTRICAL
ELECTRONIC THROTTLE
CONTROL (ETC) SWITCH
The Electronic Throttle Control (ETC) system is
designed to stop the engine of an ATV in the event of
a mechanical problem with the throttle mechanism.
The ETC switch is mounted independently of the
throttle actuator lever inside the throttle block
assembly. This is a normally closed switch, and is
held in the open position (contacts are separated (as
shown below) by throttle cable tension. The contacts
are “open” during normal operation regardless of
throttle lever position. In the event of a mechanical
problem in the throttle mechanism (cable tension is
lost), the switch contacts close, connecting the black
wire to ground, which prevents ignition spark. This is
the same as turning the key or engine stop switch
“OFF”.
NOTE: Test the ETC switch at the harness connector.
ETC will not activate unless there is throttle plate
movement off of ’zero’ detected by the ECU. Adjust
throttle cable freeplay (ETC switch) and make sure
throttle mechanism is functioning properly before
testing the switch. Refer to Maintenance Chapter 2
for cable adjustment procedure.
ETC OPERATION TEST
Remove throttle block cover by carefully releasing all
tabs around edge of cover.
Place transmission in neutral and apply parking
brake.
Start engine and open throttle lever slightly until
engine RPM is just above idle speed.
Hold throttle cable with fingers at point “A” as shown
below and release throttle lever. If the ETC system is
functioning properly, the engine will lose spark and
stop.

EFI -- DC / CDI IGNITION
The Sportsman EFI system has incorporated into it’s
design a DC/ CDI ignition system.
Some of the advantages of DC ignition are:
G Stronger, more consistent spark at
low rpm for better performance
G Easier starts
G Simpler component design for ease
trouble shooting and maintenance
NOTE:
DC/CDI systems and components are not interchangeable
with any other system. Timing curve
shown is not indicative of EFI ignition operation.
10.16
Operation Overview:
The DC/CDI system relies on battery power for ignition.
Instead of generating DC voltage via magnetic
induction, a 12 volt DC current is supplied directly to the
ECU from the battery. 12 volt DC current charges an
internal capacitor to build up the initial ignition charge.
An A/C signal from the Crank Shaft Position Sensor
is processed by the ECU, which determines ignition
timing by calculating from a point pre--determined in
the crankshaft rotation. This signal releases the
electrical charge which saturates the coil for ignition.
DC/CDI systems have the ability to ignite with as little
as 6 volts of power.

CHARGING SYSTEM “BREAK
EVEN” TEST
CAUTION: Do not allow the battery cables to

Follow the steps below as outlined to reduce the
chance of damage to electrical components.
ALTERNATOR OUTPUT TEST
Three tests can be performed using a multimeter to
determine the condition of the stator (alternator).
Y1
Y3
Y2
The “break even” point of the charging system is the
point at which the alternator overcomes all system
loads (lights, etc.) and begins to charge the battery.
Depending on battery condition and system load, the
break even point may vary slightly. The battery should
be fully charged before performing this test.
WARNING: Never start the engine with an ammeter
connected in series. Damage to the meter or meter
fuse will result. Do not run test for extended period of
time. Do not run test with high amperage accessories.
1. Connect a tachometer to the engine.
2. Using an inductive amperage metering device,
(set to DC amps) connect to the negative battery
cable
3. With engine off and the key, kill switch, and lights
in the ON position, the ammeter should read
negative amps (battery discharge). Reverse
meter lead if a positive reading is indicated.
4. Shift transmission into Park and start the engine.
With the engine running at idle, observe meter
readings.
5. Increase engine RPM while observing ammeter
and tachometer.
6. Note RPM at which the battery starts to charge
(ammeter indication is positive).

BATTERY ACTIVATION
(CONVENTIONAL)
Batteries produce explosive gases.
Keep
sparks, flame, cigarettes, etc. away. Ventilate
when charging or using in an enclosed space.
Always shield eyes when working near batteries. KEEP OUT OF REACH OF CHILDREN.
WARNING: The gases given off by a battery are
explosive. Any spark or open flame near a battery can
cause an explosion which will spray battery acid on
anyone close to it. Should there be contact with
battery acid, wash the affected area with large
quantities of cool water and seek immediate medical
attention.
To ensure maximum service life and performance
from a new battery, perform the following steps.
NOTE: Do not service the battery unless it will be put
into regular service within 30 days. After initial
service, add only distilled water to the battery.
Never add electrolyte after a battery has been in
service.
NOTE: New Battery: Battery must be fully charged
before use or battery life will be significantly reduced
10-30% of the battery’s full potential.
To activate a new battery:
1. Remove vent plug from vent fitting. Remove cell
caps.
2. Fill battery with electrolyte to upper level marks on
case.
3. Set battery aside to allow for acid absorption and
stabilization for 30 minutes.
4. Add electrolyte to bring level back to upper level
mark on case. NOTE: This is the last time that
electrolyte should be added. If the level becomes
low after this point, add only distilled water.
ELECTRICAL
5. Charge battery at 1/10 of its amp/hour rating.
Examples: 1/10 of 9 amp battery = .9 amp; 1/10
of 14 amp battery = 1.4 amp; 1/10 of 18 amp
battery = 1.8 amp (recommended charging
rates).
6. Check specific gravity of each cell with a
hydrometer to assure each has a reading of 1.270
or higher.

Refill using only distilled water. Tap water
contains minerals which are harmful to a battery.
Do not allow cleaning solution or tap water inside
the battery. Battery life may be reduced.
5. Reinstall the battery caps.
Inspect the battery fluid level. When the battery fluid
nears the lower level, remove the battery and fill with
distilled water only to the upper level line. To remove
the battery:
CONVENTIONAL BATTERY
INSTALLATION
1. Clean battery cables and terminals with a stiff wire
brush. Corrosion can be removed using a solution
of one cup water and one tablespoon baking soda.
Rinse well with clean water and dry thoroughly.
2. Route the cables correctly.
3. Reinstall battery, attaching positive (+) (red) cable
first and then the negative (-) (black) cable. Coat
terminals and bolt threads with Nyogelt Grease
(PN 2871329).
4. Install clear battery vent tube from vehicle to battery
vent. WARNING: Vent tube must be free from
obstructions and kinks and securely installed. If not,
battery gases could accumulate and cause an
explosion. The vent tube should be routed away
from frame and body to prevent contact with
10.23

electrolyte. Avoid skin contact with electrolyte, as
severe burns could result. If electrolyte contacts the
vehicle frame, corrosion will occur.
5. Reinstall the holder strap.
Battery Hydrometer (PN 2870836)
CONVENTIONAL BATTERY
TESTING
Whenever a service complaint is related to either the
starting or charging systems, the battery should be
checked first.
1.10
Battery voltage should be checked with a digital
multitester. Readings of 12.6 volts or less require
further battery testing and charging. See charts and
Load Test on below.
NOTE: Lead-acid batteries should be kept at or near
a full charge as possible. Electrolyte level should be
kept between the low and full marks. If the battery is
stored or used in a partially charged condition, or with
low electrolyte levels, hard crystal sulfation will form
on the plates, reducing the efficiency and service life
of the battery.
CONVENTIONAL BATTERY
SPECIFIC GRAVITY TEST
A tool such as a Battery Hydrometer (PN 2870836)
can be used to measure electrolyte strength or
specific gravity. As the battery goes through the
charge/discharge cycle, the electrolyte goes from a
heavy (more acidic) state at full charge to a light (more
water) state when discharged. The hydrometer can
measure state of charge and differences between
cells in a multi-cell battery. Readings of 1.270 or
greater should be observed in a fully charged battery.
Differences of more than .025 between the lowest and
highest cell readings indicate a need to replace the
battery.

CAUTION: To prevent shock or component
damage, remove spark plug high tension leads
and connect securely to engine ground before
proceeding.
NOTE: This test can only be performed on machines
with electric starters. This test cannot be performed
with an engine or starting system that is not working
properly.
A battery may indicate a full charge condition in the OCV
test and the specific gravity test, but still may not have
the storage capacity necessary to properly function in
the electrical system. For this reason, a battery capacity
ELECTRICAL
or load test should be conducted whenever poor battery
performance is encountered. To perform this test, hook
a multitester to the battery in the same manner as was
done in the OCV test. The reading should be 12.6 volts
or greater. Engage the starter and observe the battery
voltage while cranking the engine. Continue the test for
15 seconds. During cranking the observed voltage
should not drop below 9.5 volts. If the beginning voltage
is 12.6 volts or higher and the cranking voltage drops
below 9.5 volts during the test, replace the battery.
OFF SEASON STORAGE
CHARGING PROCEDURE
1. Remove the battery from the ATV to prevent
damage from leaking or spilled acid during

of the battery’s amp/hr capacity until
the electrolyte’s specific gravity
reaches 1.270 or greater.
Store the battery either in the
machine
with
the
cables
disconnected, or store in a cool
place.
NOTE: Recharge to full capacity every 30 to 60 days
during a non-use period. If the battery is stored during
the winter months, electrolyte will freeze at higher
temperatures as the battery discharges. The chart
below indicates freezing points by specific gravity.

3. Charge battery using a variable rate charger.
LOW MAINTENANCE
BATTERY CHARGING
If battery voltage is 12.8 V or less, the battery may
need recharging. When using an automatic charger,
refer to the charger manufacturer’s instructions for
recharging. When using a constant current charger,
use the following guidelines for recharging.
NOTE: Always verify battery condition before and 1-2
hours after the end of charging.
New Batteries: Batteries must be fully charged
before use or battery life can be reduced by
10-30% of full potential. Charge battery for 3--5
hours using a variable rate charger. Do not use
the alternator to charge a new battery. A high rate
battery charger can cause battery damage.
Low Maintenance batteries are permanently
sealed at the time of manufacture. The use of
lead--calcium and AGM technology instead of
lead--antimony allows the battery acid to be fully
absorbed. For this reason, a Low Maintenance
battery case is dark and the cell caps are not
removable, since there is no need to check
electrolyte level.
NEVER attempt to add electrolyte or water to a Low
Maintenance battery. Doing so will damage the
case and shorten the life of the battery. Refer to the
Battery Activation and Maintenance Video (PN
9917987) for proper instruction on servicing Low
Maintenance batteries.
NOTE: New Batteries: Batteries must be fully
charged before use or battery life will be reduced
by 10-30% of full potential. Charge battery for 3--5
hours at a current equivalent of 1/10 of the
battery’s rated amp/hour capacity. Do not use the
alternator to charge a new battery. (Refer to Battery
Activation and Maintenance video PN 9917987)
