Operating Safety
Congratulations on purchasing a superior-quality piece of
lawn and garden equipment. Our products are designed and
manufactured to meet or exceed all industry standards for safety.
Do not operate this machine unless you have been trained.
Reading and understanding this operator’s manual is a way to
train yourself.
Power equipment is only as safe as the operator. If it is misused,
or not properly maintained, it can be dangerous! Remember, you
are responsible for your safety and that of those around you.

Read the Manual
n
Use common sense, and think through what you are doing. If
you are not sure that the task you are about to perform can be
safely done with the equipment you have chosen, ask a
professional: contact your local authorized dealer.
The operator’s manual contains important safety
information you need to be aware of BEFORE you
operate your unit as well as DURING operation.
Safe operating techniques, an explanation of the
product’s features and controls, and maintenance
information is included to help you get the most out of
your equipment investment.
Be sure to completely read the Safety Rules and
Information found on the following pages. Also
completely read the Operation section.
Children
Tragic accidents can occur with children. Do
not allow them anywhere near the area of
operation. Children are often attracted to the
unit and mowing activity. Never assume that
children will remain where you last saw them.
If there is a risk that children may enter the
area where you are mowing, have another
responsible adult watch them.
2
Operator Safety
Slope Operation
Operation on slopes can be dangerous. Using the unit on a slope
that is too steep where you do not have adequate wheel traction
(and control) can cause sliding, loss of steering, control, and
possible rollover. You should not operate on a slope greater than
a 5.4 foot rise over a 20 foot length (15 degrees).
Always mow across slopes, not up and down (to maintain traction
on the wheels) and avoid sudden turns or rapid speed changes.
Reduce speed and use extreme caution on ALL slopes.
Also, note that the surface condition you are on can greatly impact
your ability to safely operate this machine. Operating on wet or
slippery slopes can cause sliding and loss of steering and control.
Do not operate on slopes that are slippery, wet, or have soft soil
conditions.
n
If you feel unsure about operating the unit on a slope, don’t do it.
It’s not worth the risk.

Thrown Objects
This unit has spinning mower blades. These blades can pick up and
throw debris that could seriously injure a bystander. Be sure to clean
up the area to be mowed and remove objects that could be thrown by
the blade BEFORE you start mowing.
Do not operate this unit without the entire grass catcher or discharge
guard (deflector) in place.
Also, do not allow anyone in the area while the unit is running! If
someone does enter the area, shut the unit off immediately until they
leave.
Moving Parts
This equipment has many moving parts that can injure
you or someone else. However, if you stay in the
operator zone (stay seated in the seat), and follow the
safety rules in this operator’s manual, the unit is safe to
operate.
The mower deck has spinning mower blades that can
amputate hands and feet. Do not allow anyone near the
unit while it is running! Keep safety devices (guards,
shields, and switches) in place and working.
To help you, the operator, use this equipment safely, it
is equipped with an operator-present safety system. Do
NOT attempt to alter or bypass the system. See your
dealer immediately if the system does not pass all the
safety interlock system tests found in this manual.

Operator Safety
Roll Bar Use
Keep the roll bar in the raised position and fasten the
seat belt. There is no roll over protection when the
roll bar is down! Do not jump off if the mower tips (it
is safer to be secured by the seat belt with the roll bar
raised.)

Retaining Walls, Dropoffs, and Water
n
Lower the roll bar only when necessary (such as to
temporarily clear a low overhanging obstacle) and
NEVER remove it. Do NOT use the seat belt when
the roll bar is down. Raise the roll bar as soon as
clearance permits.
Retaining walls and drop-offs around steps and
water are a common hazard. Give yourself a
minimum of two mower widths of clearance
around these hazards and hand-trim with a
walk behind mower or string trimmer. Wheels
dropping over retaining walls, edges, ditches,
embankments, or into water can cause rollovers,
which may result in serious injury, death, or
drowning.
Overhead Obstacles
Check for overhead clearances before driving
under any objects. Do not allow the roll bar to
contact low overhanging obstacles such as tree
branches and guide wires.

Operator Safety
Fuel and Maintenance
Always disengage all drives, shutoff the engine, and
remove the key before doing any cleaning, refueling, or
servicing.
Gasoline and its vapors are extremely flammable. Do not
smoke while operating or refueling. Do not add fuel while
engine is hot or running. Allow engine to cool for at least
3 minutes prior to adding fuel.
Do not add fuel indoors, in an enclosed trailer, garage,
or any other enclosed area that is not well ventilated.
Gasoline spills should be cleaned up promptly and before
operation begins.

and DO NOT START OR STOP ON SLOPE.
Do
1. Mow across slopes, not up and down.
2. Remove obstacles such as rocks, tree limbs, etc.
3. Watch for holes, ruts, or bumps. Uneven terrain
could overturn the unit. Tall grass can hide
obstacles.
4. Use slow speed. Choose a slow speed so that
you will not have to stop or change speed while
on the slope.
*This limit was determined per CEN Standard EN 836:1997, Section
5.2.2 and is based on the EN 836 Stability Test procedure described in
Section 4.2.4.2. The 15 degree “limit of stability” is equal to 50% of the
angle at which machine lift-off occurred in static tests. Actual dynamic
stability may vary depending on operating conditions.

Control Functions
The information below briefly describes the function of individual controls. Starting, stopping, driving, and
mowing require the combined use of several controls applied in specific sequences. To learn what combination
and sequence of controls to use for various tasks see the OPERATION section.
Ground Speed Levers
These levers control the ground speed of the rider.
The left lever controls the left rear drive wheel and
the right lever controls the right rear drive wheel.
Moving a lever forward increases the FORWARD
speed of the associated wheel, and pulling back on a
lever increases the REVERSE speed.
Note: The further a lever is moved away from the
neutral position the faster the drive wheel will turn.
See the Operating the Zero Turn Rider section for
steering instructions.
Ignition Switch
(S/N: 2015276814 & Below):
The ignition switch starts and stops the engine, it has
four positions:
HEAT
Heats the glow plugs.
OFF
Stops the engine and shuts off the
electrical system.
RUN
Allows the engine to run, powers the
electrical system and primes the fuel
system
START Cranks the engine for starting.
Seat Adjustment Lever
The seat can be adjusted forward and back.
S/N: 2014582798 & Below: Move the lever forward,
position the seat as desired, and release the lever to
lock the seat in position.
NOTE: Never leave the ignition switch in the ON
position with the engine stopped–this drains the
battery.
S/N: 2014582799 & Above: Move the lever towards
the left, position the seat as desired, and release the
lever to lock the seat in position.
15

RUN
Turning the key to this position prior
to starting the engine heats the glow
plugs. After the engine starts the
ignition returns to this position and
allows the engine to run and powers
the electrical system.
START Cranks the engine for starting.
NOTE: Never leave the ignition switch in the ON
position with the engine stopped–this drains the
battery.
PTO (Power Take Off) Switch
These control the cutting height of the mower deck.
Depress the pedal until it locks into the 5” (12,7 cm)
position. Place the adjustment pin in the desired
cutting height and release the lift lock lever.
Hour Meter
Measures the time of the PTO being engaged. The
hour meter measures the number of hours the PTO
has been engaged.
Note: The hour meter will register the passage of time
only when the PTO is engaged. The hour meter has
a self contained power source so the total hours are

Zero-Turn Driving Practice
Smooth Travel
The lever controls of the Zero Turn rider are
responsive. Learning how to gain smooth, efficient
control of the rider’s forward, reverse, and turning
movements will take some practice.
The lever controls of
the Zero Turn rider are
responsive.
Locate a smooth, flat area of your lawn — one
with plenty of room to maneuver. (Clear the area
of objects, people and animals before you begin.)
Operate the unit at mid-throttle during this practice
session (ALWAYS operate at full throttle when
mowing), and turn slowly to prevent tire slippage and
damage to your lawn.
We suggest you begin with the Smooth Travel
procedure to the right, and then advance through the
forward, reverse, and turning maneuvers.
BASIC DRIVING
FIRST place your
hands onto the levers
as shown.
SECOND, to go
forward gradually push
the levers forward with

ADVANCED DRIVING
Executing an End-Of-Row Zero Turn
Your Zero Turn Rider’s unique ability to turn
in place allows you to turn around at the end
of a cutting row, rather than having to stop
and Y-turn before starting a new row.
For example, to execute a left end-of row
zero turn:
1. Slow down at the end of the row.
2. Move the RIGHT ground speed control
lever forward slightly while moving the
LEFT ground speed control lever back to
center and then slightly back from center.
3. Begin mowing forward again.
This technique turns the rider LEFT and
slightly overlaps the row just cut eliminating
the need to back up and re-cut missed grass.
As you become more familiar and
experienced with operating the Zero Turn
rider. You will learn more maneuvers that
will make your mowing time easier and more
enjoyable.
Remember, the more you practice, the
better your control of the Zero Turn will
be!

Operation
Mowing
1. Engage the parking brake. Make sure the PTO
switch is disengaged, the motion control levers
are locked in the NEUTRAL position, and the
operator is on the seat.
2. Start the engine (see STARTING THE ENGINE).
3. Set the mower cutting height.
4. Set the throttle to FULL.
5. Engage the PTO by pulling up on the PTO switch.
6. Begin mowing.
7. When finished, shut off the PTO.
8. Stop the engine (see STOPPING THE TRACTOR

Proper Cutting Height
Mowing Recommendations
Several factors can affect how well your machine cuts
grass. Following proper mowing recommendations
can improve the performance and life of your
machine.
Tall Grass Requires Incremental Cutting
Height of Grass
Don’t cover the grass surface with a heavy layer of
clippings. Consider using a grass collection system
and starting a compost pile.
n
N
o
R tf
ep o
r
ro
du
ct
io
Often cutting height is a matter of personal
preference. Typically, you should mow the grass
when it is between three and five inches high. The
proper cutting height range for a specific lawn will
depend upon several factors including the following:
the type of grass, the amount of rainfall, the prevailing
temperature, and the lawn’s overall condition.
For extremely tall grass, set the cutting height at
maximum for the first pass, and then reset it to the
desired height and mow a second or third time.
Cut Here On
First Pass
Cutting the grass too short causes weak, thin grass
plants, which are easily damaged by dry periods and
pests. Cutting too short is often more damaging than
allowing the grass to be slightly higher.
Letting grass grow a bit longer especially when it is
hot and dry reduces heat build-up, preserves needed
moisture, protects the grass from heat damage and
other problems. However, allowing grass to grow too
high can cause thin turf and additional problems.
Cut
Here On
Second
Pass
Incremental Cutting
Cutting off too much at one time shocks the plant’s
growth system and weakens the grass plants. A
good rule of thumb is the 1/3 rule: to cut no more
than one third of the grass height, and never
more than 1 inch at a time.
The amount of grass you are able to cut in one pass
is also effected by the type of mowing system you are
using (for example, broadcasting with side discharge
decks can process a much larger volume of grass
than mulching does).
22
www.ferrisindustries.com
Operation
When and How Often to Mow
The time of day and condition of the grass greatly
affect the results you’ll get when mowing. For the
best results, follow these guidelines:
1. Mow when the grass is between three and five
inches high.
2. Mow with sharp blades. Short clippings of grass
one inch or shorter decompose more quickly than
longer blades. Sharp mower blades cut grass
cleanly and efficiently, preventing frayed edges
which harm the grass.
3. Mow at time of day when the grass is cool and
dry. Late afternoon or early evening often provide
these ideal mowing conditions.
Where possible, make one or two passes around the
outside of the area discharging the grass INTO the
lawn to keep the cut grass off fences and walks.
4. Avoid mowing after rain or even heavy dew.
Never mulch when the grass is wet (moist grass
does not mulch well and clumps beneath the
mower deck).
Always start mowing on a smooth, level area.
The remainder of the mowing should be done in the
opposite direction so that the clippings are dispersed
OUT onto the area of lawn previously cut.
N
o
R tf
ep o
r
ro
du
ct
io
The size and type of area to be mowed will determine
the best mowing pattern to use. Obstructions such
as trees, fences, buildings, and conditions such as
slopes and grades must also be considered.
n
Mowing Patterns
1. Cut long straight strips overlapping slightly.
2. Whenever possible, change patterns to eliminate
matting, graining, or a corrugated appearance.
3. For a truly professional cut, mow across the lawn
in one direction, then recut the lawn by mowing
perpendicular to the previous cut.
Mowing Methods
Proper Broadcast Mowing
Broadcasting (side discharging), disperses fine
clippings evenly over the entire lawn. Many golf
courses use this method. Your mower has a deep
dish deck to allow freer circulation of clippings so they
are broadcast evenly over the lawn.
Engine Speed & Ground Speed for
Broadcasting
ALWAYS operate the engine at full throttle when
mowing.
ALWAYS use an appropriate ground speed for the
thickness and height of the grass you are cutting (3rd
gear or slower for manual gear models). If you hear
the engine slowing down, you are mowing too fast,
using a slower ground speed will improve the cutting
efficiency of the blades and prevents many common
cutting problems.
How Much Grass to Cut Off When
Broadcasting
Mow when the grass is 3-5 inches long. Do NOT cut
the grass shorter than 2 to 2-1/2 inches. Do NOT cut
off more that 1 inch of grass in a single pass.
23
Operation
Proper Mulching
Attaching a Trailer
Mulching consists of a mower deck which cuts and
recuts clippings into tiny particles and then blows
them down INTO the lawn. These tiny particles
decompose rapidly into by-products your lawn can
use. UNDER PROPER CONDITIONS, your mulching
mower will virtually eliminate noticeable clippings on
the lawn surface.
The maximum weight of a towed trailer should be
less than 200 lbs (91kg). Secure the trailer with a
appropriately sized clevis pin (A, Figure 10) and clip
(B).
Mulching Requires EXCELLENT Mowing
Conditions
Mulching mowers cannot function properly if the
grass is wet, or if the grass is simply too high to
cut. Mulching requires that the grass be dry and the
appropriate amount be cut.
Do NOT use the mower as a mulching mower during
the first two or three mowings in the spring. The
long grass blades, quick growth, and often wetter
conditions are more suitable for broadcasting (sidedischarging) or grass bagging operation.

Engine Speed & Ground Speed for mulching
A
n
NOTE: When mulching under heavy cutting
conditions, a rumbling sound may be present and is
normal.
Excessive towed weight can cause loss of traction
and loss of control on slopes. Reduce towed weight
when operating on slopes. The surface being driven
on greatly impacts traction and stability. Wet or
slippery surfaces can greatly reduce traction and the
ability to stop or turn. Carefully evaluate the surface
conditions before operating the unit and trailer.
NEVER operate on slopes greater than 10°. See
SLOPE OPERATION and TOWED EQUIPMENT in
the safety section of this manual for additional safety
information.
Use full engine throttle matched with a slow ground
speed so that clippings will be finely cut. Ground
speed while mulching should be HALF of the
speed that would be used when broadcasting (side
discharging) under similar conditions. Since mulching
requires more horsepower than broadcasting, using
a slower ground speed is vitally important for proper
mulching operation.
B
How Much Grass to MULCH
The best mulching action typically results from cutting
only the top 1/2 inch to 3/4 inch of grass blade. This
provides short clippings which decompose properly
. The ideal cutting height will vary with climate, time
of year, and quality of your lawn. We recommend
that you experiment with both the cutting height and
ground speed until you achieve the best cut. Start
with a high cutting height and using progressively
lower settings until you find a cutting height that is
matched to your mowing conditions and preferences.

surface, chock the wheels.
• Clean all grass and dirt from the mower.
• If temperature is expected to drop below 35 degrees,
refer to Long Term Storage, Item 2.
Long Term Storage (Longer Than 30 Days)
Before you store your unit for the off-season, read the
Maintenance and Storage instructions in the Safety
Rules section, then perform the following steps:
1. Drain crankcase oil while engine is hot and refill with
a grade of oil that will be required when unit is used
again.
Never store the unit, with diesel fuel in engine
or fuel tank, in a heated shelter or in enclosed,
poorly ventilated enclosures. Diesel fumes
may reach an open flame, spark or pilot light
(such as a furnace, water heater, clothes dryer,
etc.) and cause an explosion.
Handle diesel fuel carefully. It is highly
flammable and careless use could result in
serious fire damage to your person or property.
Drain fuel outdoors into an approved container
and away from open flame or sparks.
NOTE: Diesel fuel, if permitted to stand unused for
extended periods (30 days or more), may develop
gummy deposits which can adversely affect the fuel
pump and injector tubes and cause engine malfunction.
To avoid this condition, add a diesel fuel stabilizer to the
fuel tank and run the engine a few minutes, or drain all
fuel from the unit before placing it in storage.

3. Prepare the mower deck for storage as follows:
a.Remove mower deck from the unit.
b.Clean underside of mower deck.
c.Coat all bare metal surfaces with paint or light coat
of oil to prevent rusting.
4. Clean external surfaces and engine.
5. Prepare engine for storage. See engine owner’s manual.
6. Clean any dirt or grass from cylinder head, engine
housing and air cleaner element.
7. Cover air cleaner and exhaust outlet tightly with
plastic or other waterproof material to keep out
moisture, dirt and insects.
8. Completely grease and oil unit as outlined in the
Regular Maintenance section.
9. Clean up unit and apply paint or rust preventative to
any areas where paint is chipped or damaged.
10.Be sure the battery is filled to the proper level
with water and is fully charged. Battery life will be
increased if it is removed, put in a cool, dry place
and fully charged about once a month. If battery is
left in unit, disconnect the negative cable.
11.Drain fuel system completely or add a diesel fuel
stabilizer to the fuel system. If you have chosen to
use a fuel stabilizer and have not drained the fuel
system, follow all safety instructions and storage
precautions in this manual to prevent the possibility
of fire from the ignition of diesel fumes. Remember,
diesel fumes can travel to distant sources of ignition
and ignite, causing risk of explosion and fire.
26
Before starting the unit after it has been stored for a long
period of time, perform the following steps.
1. Remove any blocks from under the unit.
2. Install the battery if it was removed.
3. Unplug the exhaust outlet and air cleaner.
4. Fill the fuel tank with fresh fuel. See engine manual
for recommendations.
5. See engine owner’s manual and follow all
instructions for preparing engine after storage.
6. Check crankcase oil level and add proper oil if
necessary. If any condensation has developed
during storage, drain crankcase oil and refill.
7. Inflate tires to proper pressure. Check fluid levels.
8. Start the engine and let it run slowly. DO NOT run at
high speed immediately after starting. Be sure to run
engine only outdoors or in well ventilated area.
Diesel Fuel Recommendations
Fuel companies provide fuel tailored to meet the existing
weather conditions. These fuels change at the start of
the predominant season according to regional weather
trends.
Winter fuels are tailored to give ease of starting for cold
weather. Summer fuel may be somewhat heavier than
winter fuel resulting in slightly better fuel economy and
power. Spring and fall fuel is an average blend between
winter and summer blend.
For these reasons an effort should be made to purchase
fuels in such quantities that they are not carried over
into the next season. Using the wrong blend of fuel can
cause problems with the engine.
Refer to the engine manufacturer’s manual for specific
fuel recommendations.

Neutral Adjustment
If the tractor “creeps” while the ground speed control
levers are locked in NEUTRAL, then it may be
necessary to adjust the linkage rod.
NOTE: Perform this adjustment on a hard, level
surface such as a concrete floor.
Return-to-Neutral Adjustment
To determine if it is necessary to adjust the neutral
return, perform the following steps.
1. Disengage the PTO, engage the parking brake
and turn off the engine.
2. Move the ground speed control levers into the
operating position, pull levers rearward and
release.
3. Move the ground speed control levers out towards
the neutral position. If the levers do not align
with the notches in the neutral lock plate, it is
necessary to adjust the neutral return rod.

Troubleshooting, Adjustment & Repair
Suspension Adjustment
To adjust the spring pre-load:
The shock assembly can be adjusted to vary the
amount of pre-load applied to the springs. This allows
the operator to maintain the ride height.
1. Park machine on a flat, level surface. Disengage
the PTO, stop the engine and engage the parking
brake.
2. See Figure 43. Using the supplied spanner
wrench (p/n 5022853), insert the tip of the
wrench into the notch in the pre-load adjuster.
While holding the wrench with both hands, turn
CLOCKWISE to decrease the pre-load, turn
COUNTER-CLOCKWISE to increase the preload. Make sure that for each pair of shocks that
the left-hand and right-hand are set to the same
amount of pre-load.
NOTE: Spanner wrench is located under the seat.
Rear tires must be removed to adjust the rear
suspension.
Use less pre-load for light weight operators. Use
more pre-load for heavy weight operators.
WARNING
Use two hands when adjusting the shock
springs. This will prevent the wrench from
slipping while pressure is being applied.
NOTE: It is recommended that the rear suspension
be adjusted stiffer due to the added weight of the
collection system.

engine looses oil pressure or begins to overheat.
What to do if the deck shuts down during
operation:
A
B
• Immediately check your dash panel to see if the
oil pressure indicator lamp (A, Figure 62) is lit or
the water temperature gauge (B) is reading a high
temperature.
If the oil pressure indicator lamp is lit:
• Shut the unit off immediately and see your dealer.
If the water temperature gauge reads a high
temperature:
• Move the ground speed control levers to the
neutral position, disengage the PTO switch,
engage the parking brake and reduce to half
throttle speed. Leave the engine running so the
radiator fan will continue to run and coolant will
continue to circulate.
• Check the engine coolant level. See Check Engine
Coolant Level. Add coolant if necessary.
• Check to see if the radiator screen is dirty or
plugged. See Clean Radiator & Screen. Clean
radiator screen if necessary.

Troubleshooting, Adjustment & Repair
WARNING
Keep open flames and sparks away from the
battery; the gasses coming from it are highly
explosive. Ventilate the battery well during
charging.
Checking Battery Voltage
A voltmeter can be used to determine condition of
battery. When engine is off, the voltmeter shows
battery voltage, which should be 12 volts. When
engine is running, the voltmeter shows voltage of
charging circuit which normally is 13 to 14 volts.
Jump Starting With Auxiliary (Booster) Battery
Jump starting is not recommended. However, if it
must be done, follow these directions. Both booster
and dis-charged batteries should be treated carefully
when using jumper cables. Follow the steps below
EXACTLY, being careful not to cause sparks. Refer
to Figure 63.
1. Both batteries must be of the same voltage.
2. Position the vehicle with the booster battery
adjacent to the vehicle with the discharged battery
so that booster cables can be connected easily
to the batteries in both vehicles. Make certain
vehicles do not touch each other.
3. Wear safety glasses and shield eyes and face
from batteries at all times. Be sure vent caps are
tight. Place damp cloth over vent caps on both
batteries.
4. Connect positive (+) cable to positive post of
discharged battery (wired to starter or solenoid).
5. Connect the other end of same cable to same
post marked positive (+) on booster battery.
6. Connect the second cable negative (-) to other
post of booster battery.
7. Make final connection on engine block of stalled
vehicle away from battery. Do not lean over
batteries.
8. Start the engine of the vehicle with the booster
battery. Wait a few minutes, then attempt to start
the engine of the vehicle with the discharged
battery.
9. If the vehicle does not start after cranking for thirty
seconds, STOP PROCEDURE. More than thirty
seconds seldom starts the engine unless some
mechanical adjustment is made.
10.After starting, allow the engine to return to idle
speed. Remove the cable connection at the
engine or frame. Then remove the other end of
the same cable from the booster battery.
11.Remove the other cable by disconnecting at the
discharged battery first and then disconnect the
opposite end from the booster battery.
12.Discard the damp cloths that were placed over the
battery vent caps.

A dead battery or one too weak to start the engine
may not mean the battery needs to be replaced.
For example, it may mean that the alternator is not
charging the battery properly. If there is any doubt
about the cause of the problem, see your dealer.
If you need to replace the battery, follow the steps
under Cleaning the Battery & Cables in the Regular
Maintenance Section.

Battery Service
Charging a Completely Discharged Battery
1. Be aware of all the safety precautions you should
observe during the charging operation. If you are
unfamiliar with the use of a battery charger and
hydrometer, have the battery serviced by your
dealer.
2. Add distilled water sufficient to cover the plate (fill
to the proper level near the end of the charge).
If the battery is extremely cold, allow it to warm
before adding water because the water level will
rise as it warms. Also, an extremely cold battery
will not accept a normal charge until it becomes
warm.
3. Always unplug or turn the charger off before
attaching or removing the clamp connections.
4. Carefully attach the clamps to the battery in
proper polarity (usually red to [+] positive and
black to [-] negative).
5. While charging, periodically measure the
temperature of the electrolyte. If the temperature
exceeds 125° F (51.6° C), or if violent gassing or
spewing of electrolyte occurs, the charging rate
must be reduced or temporarily halted to prevent
battery damage.
6. Charge the battery until fully charged (until the
specific gravity of the electrolyte is 1.250 or higher
and the electrolyte temperature is at least 60° F).
The best method of making certain a battery is
fully charged, but not over charged, is to measure
the specific gravity of a cell once per hour. The
battery is fully charged when the cells are gassing

MAKE CERTAIN VEHICLES DO NOT TOUCH
Figure 63. Jump Starting
WARNING
Any procedure other than the preceding could
result in:
(1) personal injury caused by electrolyte
squirting out the battery vents,
(2) personal injury or property damage due
to battery explosion,
(3) damage to the charging system of the
booster vehicle or of the immobilized
vehicle.
Do not attempt to jump start a vehicle having a
frozen battery because the battery may rupture
or explode. If a frozen battery is suspected,
examine all fill vents on the battery. If ice
can be seen or if the electrolyte fluid cannot
be seen, do not attempt to start with jumper
cables as long as the battery remains frozen.
WARNING
For your personal safety, use extreme care
when jump starting. Never expose battery to
open flame or electric spark – battery action
generates hydrogen gas which is flammable
and explosive. Do not allow battery acid to
contact skin, eyes, fabrics, or painted surfaces.
Batteries contain a sulfuric acid solution which
can cause serious personal injury or property
damage.
When removing or installing battery cables,
disconnect the negative cable FIRST and
reconnect it LAST. If not done in this order, the
positive terminal can be shorted to the frame
by a tool.
To avoid engine damage, do not disconnect
battery while engine is running. Be sure
terminal connections are tight before starting.

Length of Coverage
For a period of two years from date of original purchase, B&S warrants to the original
purchaser and each subsequent purchaser that the engine is designed, built, and
equipped so as to conform with all applicable regulations adopted by the Air
Resources Board; that it is free from defects in material and workmanship that could
cause the failure of a warranted part; and that it is identical in all material respects to
the engine described in the manufacturer’s application for certification. The warranty
period begins on the date the engine is originally purchased.
4.
Coverage shall extend to the failure of any engine components caused by the
failure of any warranted emissions parts.
Claims and Coverage Exclusions
Warranty claims shall be filed according to the provisions of the B&S engine
warranty policy. Warranty coverage does not apply to failures of emissions parts
that are not original equipment B&S parts or to parts that fail due to abuse, neglect,
or improper maintenance as set forth in the B&S engine warranty policy. B&S is not
liable for warranty coverage of failures of emissions parts caused by the use of
add-on or modified parts.
Look For Relevant Emissions Durability Period and Air Index Information
On Your Small Off-Road Engine Emissions Label
Engines that are certified to meet the California Air Resources Board (CARB) small
off-road Emissions Standard must display information regarding the Emissions Durability
Period and the Air Index. Briggs & Stratton makes this information available to the
consumer on our emissions labels. The engine emissions label will indicate certification
information.
The Emissions Durability Period describes the number of hours of actual running time
for which the engine is certified to be emissions compliant, assuming proper
maintenance in accordance with the Operating & Maintenance Instructions. The
following categories are used:
Moderate:
Engine is certified to be emissions compliant for 125 hours of actual engine running time.
Intermediate:
Engine is certified to be emissions compliant for 250 hours of actual engine running time.
Extended:
Engine is certified to be emissions compliant for 500 hours of actual engine running time.
For example, a typical walk-behind lawn mower is used 20 to 25 hours per year.
Therefore, the Emissions Durability Period of an engine with an intermediate rating
would equate to 10 to 12 years.
Briggs & Stratton engines are certified to meet the United States Environmental
Protection Agency (USEPA) Phase 2 or Phase 3 emissions standards. The Emissions
Compliance Period referred to on the Emissions Compliance label indicates the number
of operating hours for which the engine has been shown to meet Federal emissions
requirements.
For engines less than 225 cc displacement.
Category C = 125 hours, Category B = 250 hours, Category A = 500 hours
For engines of 225 cc or more displacement.
Category C = 250 hours, Category B = 500 hours, Category A = 1000 hours
