Safety information
ESU10183
As the vehicle’s owner, you are responsible
for the safe and proper operation of your
snowmobile. When you ride your snowmobile, you must know and use the following for
your safety. Severe injury or death may result
if you ignore any of the following.
●
While using your snowmobile
●
Before you operate your snowmobile
●
●
Read the Owner’s Manual and all labels.
Become familiar with all of the operating
controls and their function. Consult a
Yamaha dealer about any control or function you do not understand.
Wear protective clothing. Wear an approved helmet, and a face shield or goggles. Also, wear a good quality snowmobile
suit, boots, and a pair of gloves or mittens
that will permit use of your thumbs and fingers for operation of the controls.
●
●
●
Do not operate the snowmobile after or
while drinking alcohol or taking drugs. Your
ability to operate the snowmobile is reduced by the influence of alcohol or drugs.
●
Prepare your snowmobile
●
6
Perform the pre-operation checks each
time you use the vehicle to make sure it is
in safe operating condition. Failure to inspect or maintain the vehicle properly increases the possibility of an accident or
equipment damage. See page 35 for a list
of pre-operation checks.
Apply the parking brake before starting the
engine. Never drive the snowmobile with
the parking brake applied. This may overheat the brake disc and reduce braking ability.
●
This snowmobile was not manufactured for
use on public streets, roads, or highways.
Such use is prohibited by law, and you
could collide with another vehicle.
This snowmobile is designed to carry the
OPERATOR ONLY. Passengers are prohibited. Carrying a passenger can cause
loss of control.
Be careful where you ride. There may be
obstacles hidden beneath the snow. Stay
on established trails to minimize your exposure to hazards. Ride slowly and cautiously
when you ride off of established trails. Hitting a rock or stump, or running into wires
could cause an accident and injury.
This snowmobile is not designed for use on
surfaces other than snow or ice. Use on dirt,
sand, grass, rocks, or bare pavement may
cause loss of control and may damage the
snowmobile.
Always ride with other snowmobilers when
going on a ride. You may need help if you
run out of fuel, have an accident, or damage
your snowmobile.
U8HG10E0.book Page 7 Tuesday, May 18, 2010 5:39 PM
Safety information
●
Many surfaces such as ice and hardpacked
snow require much longer stopping distances. Be alert, plan ahead and begin decelerating early. The best braking method on
most surfaces is to release the throttle and
apply the brake gently—not suddenly.
Avoid carbon monoxide poisoning
All engine exhaust contains carbon monoxide, a deadly gas. Breathing carbon monoxide
can cause headaches, dizziness, drowsiness,
nausea, confusion, and eventually death.
Carbon monoxide is a colorless, odorless,
tasteless gas which may be present even if
you do not see or smell any engine exhaust.
Deadly levels of carbon monoxide can collect
rapidly and you can quickly be overcome and
be unable to save yourself. Also, deadly levels of carbon monoxide can linger for hours or
days in enclosed or poorly-ventilated areas. If
you experience any symptoms of carbon
monoxide poisoning, leave the area immediately, get fresh air, and SEEK MEDICAL
TREATMENT.
● Do not run the engine indoors. Even if you
try to ventilate engine exhaust with fans or
open windows and doors, carbon monoxide
can rapidly reach dangerous levels.
● Do not run the engine in poorly ventilated or
partially enclosed areas such as barns, garages, or carports.
● Do not run the engine outdoors where engine exhaust can be drawn into a building
through openings such as windows and
doors.
Genuine Yamaha Accessories
cessories or offer other modifications for
Yamaha vehicles. Yamaha is not in a position
to test the products that these aftermarket
companies produce. Therefore, Yamaha can
neither endorse nor recommend the use of
accessories not sold by Yamaha or modifications not specifically recommended by
Yamaha, even if sold and installed by a
Yamaha dealer.
Maintenance and storage
●
●
●
●
●
When laying the snowmobile on its side for
maintenance, use a suitable stand to keep
it in a stable and level position.
Do not leave the snowmobile on its left side
for an extended period of time. Fuel may
leak out from the fuel breather hose.
Do not allow anyone to stand behind the
snowmobile when starting, inspecting, or
adjusting the snowmobile. A broken track,
track fittings, or debris thrown by the track
could be dangerous to the operator or bystanders.
Modifications made to the snowmobile not
approved by Yamaha, or the removal of
original equipment may render your snowmobile unsafe for use, which may cause severe personal injury. Modifications may
also make the snowmobile illegal to use.
Never store the snowmobile with fuel in the
fuel tank inside a building where ignition
sources are present such as hot water and
space heaters, an open flame, sparks,
clothes dryers, and the like. Allow the engine to cool off before storing the snowmobile in an enclosed space.
Choosing accessories for your snowmobile is
an important decision. Genuine Yamaha Accessories, which are available only from a
Yamaha dealer, have been designed, tested,
and approved by Yamaha for use on your
snowmobile. Many companies with no connection to Yamaha manufacture parts and ac-

WARNING
If the T.O.R.S. is activated, make sure that
the cause of the malfunction has been corrected and that the engine can be operated
without a problem before restarting the
engine. Continuing to operate with a malfunction could cause loss of control or
damage.

TIP
The headlights and taillight come on after the
engine is started.
ESU10312
If the throttle valves or throttle cable malfunctions during operation, the T.O.R.S. will be activated when the throttle lever is released.
The T.O.R.S. is designed to override the fuel
injection and limit the engine speed to less
than the clutch engagement speed if the throttle valves fail to return to the idle position
when the throttle lever is released. (See page
88 for the clutch engagement speed.)
Throttle lever
Once the engine is running cleanly, squeezing the throttle lever will increase the engine
speed and cause engagement of the drive
train. Regulate the speed of the snowmobile
by varying the throttle position. Because the
throttle is spring-loaded, the snowmobile will
decelerate, and the engine will return to idle
when it is released.

WARNING
Gasoline and gasoline vapors are extremely flammable. To avoid fires and explosions and to reduce the risk of injury
when refueling, follow these instructions.
Make sure there is sufficient gasoline in the
tank.
1. Before refueling, turn off the engine and
be sure that nobody is on the snowmobile. Never refuel while smoking, or while
in the vicinity of sparks, open flames, or
other sources of ignition such as the pilot
lights of water heaters and clothes dryers.
2. Do not overfill the fuel tank. Stop filling
when the fuel reaches the bottom of the
filler tube. Because fuel expands when it
heats up, heat from the engine or the sun
can cause fuel to spill out of the fuel tank.

Oxygenated fuels (gasohol) containing
a maximum 10% of ethanol (E10) can be
used, although richer jetting may be required to prevent engine damage. Consult a Yamaha dealer. Gasohol
containing methanol is not recommended.
Make sure that snow or ice does not enter the fuel tank when refueling.
Do not use alcohol deicers or water absorbing additives with oxygenated fuel.
The fuel tank should be filled with the
recommended gasoline. The use of other gasoline will cause severe damage to
internal engine parts, such as the valves
and piston rings, as well as to the exhaust system.

Suspension
The suspension can be adjusted to suit rider
preference. Softer settings, for example, may
provide greater rider comfort, while harder
settings may allow more precise handling and
control over certain types of terrain or riding
conditions.
If you are not familiar with suspension adjustments, have a Yamaha dealer make these
adjustments.

WARNING
Read and understand the following information before handling shock absorbers
that contain highly pressurized nitrogen
gas.
●
Do not tamper with or attempt to open
the cylinder assemblies.
Do not subject the shock absorbers to
an open flame or other high heat source.
This may cause the unit to explode due
to excessive gas pressure.
Do not deform or damage the cylinders
in any way. Cylinder damage will result
in poor damping performance.
Do not dispose of a damaged or worn
out shock absorber yourself. Take the
shock absorber to a Yamaha dealer for
any service.

TIP
This model is equipped with:
● an engine oil pressure switch to stop the engine in case an engine oil pressure drop is
detected. To start the engine after this system has stopped the engine, be sure to
place the snowmobile on a level surface,
and then turn the key in the main switch to
the off position, and then to the on position.
Failing to do so will prevent the engine from
starting even though the engine will crank
when turning the key to the start position. If
the engine does not start or if it stops again,
ask a Yamaha dealer to inspect the snowmobile.
● an engine overheating prevention system,
which prevents overheating when the engine is idling. When the engine has been
idling for 3 minutes or longer and the coolant temperature has risen above 100 °C
(212 °F), the engine automatically stops to
prevent overheating. The engine can be
started after it stops.

Break-in
There is never a more important period in the
life of your engine than the period between 0
and 500 km (300 mi). For this reason, you
should read the following material carefully.
Since the engine is brand new, do not put an
excessive load on it for the first 500 km (300
mi). The various parts in the engine wear and
polish themselves to the correct operating
clearances. During this period, prolonged fullthrottle operation or any condition that might
result in engine overheating must be avoided.
Operating your snowmobile for the
first time
Start the engine and let it idle for 15 minutes.
0–160 km (0–100 mi)
Avoid prolonged operation above 6000 r/min.
160–500 km (100–300 mi)
Avoid prolonged operation above 8000 r/min.
500 km (300 mi) and beyond
The snowmobile can now be operated normally.

Riding your snowmobile
Getting to know your snowmobile
EWS00211
WARNING
To avoid severe injury or death:
● Keep both hands on the handlebar during operation.
● Never put your feet outside the running
boards.
● Avoid higher speeds or more difficult
maneuvers until you have become thoroughly familiar with your snowmobile
and all of its controls.
A snowmobile is a rider active vehicle, and
your riding position and your balance are the
two basic factors of maneuvering your snowmobile.
Riding your snowmobile requires skills acquired through practice over a period of time.
Take the time to learn the basic techniques
well before attempting more difficult maneuvers.
Riding your new snowmobile can be a very
enjoyable activity, providing you with hours of
pleasure. However, it is essential to familiarize yourself with the operation of the snowmobile to achieve the skill necessary to enjoy
riding safely. Before operating the snowmobile, read this Owner’s Manual completely
and understand the operation of the controls.
U8HG10E0.book Page 39 Tuesday, May 18, 2010 5:39 PM

Pay particular attention to the safety information on page 6.
Please read all warning and notice labels on
your snowmobile. Also, read the Snowmobiler’s Safety Handbook that is supplied with
your snowmobile.

EWS00220
WARNING
●
Learning to ride your snowmobile
Before you ride, always perform the pre-operation checks listed on page 35. The short time
spent checking the condition of the snowmobile will be rewarded with added safety and a
more reliable snowmobile. Always wear the
proper clothing for both warmth and to help
protect you from injury if an accident occurs.
Become familiar with operating your snowmobile at low speeds, even if you are an experienced rider. Do not attempt to operate at
maximum performance until you are totally familiar with the snowmobile’s handling and
performance characteristics.
The beginning operator should select a large
flat area to become familiar with the snowmobile. Make sure that this area is free of obstacles and other traffic. You should practice
control of the throttle and brake, and master
turning techniques in this area before trying
more difficult terrain.
Set the parking brake and follow the instructions on page 37 to start the engine. Once the
engine has warmed up, you are ready to begin riding your snowmobile.
●
Many surfaces such as ice and hardpacked snow require much longer stopping distances. Be alert, plan ahead, and
begin decelerating early.
Improper use of the brake can cause the
drive track to lose traction, reduce control, and increase the possibility of an
accident.
When slowing down or stopping, release the
throttle and apply the brake gently—not suddenly.
Turning
For most snow surfaces, “body English” is the
key to turning.
As you approach a curve, slow down and begin to turn the handlebar in the desired direction. As you do so, put your weight on the
running board to the inside of the turn and
lean your upper body into the turn.
To start out and accelerate
1.
2.
With the engine idling, release the parking brake.
Apply the throttle slowly and smoothly.
The V-belt clutch will engage and you will
start to accelerate. WARNING! Do not
allow anyone to stand behind the
snowmobile when starting the engine.
A broken track, track fittings, or debris
thrown by the track could be dangerous to bystanders. [EWS00690]
This procedure should be practiced at low
speeds many times, in a large flat area with no
obstacles. Once you have learned this technique, you should be able to perform it at higher speeds or in tighter curves. Lean more as
the turn gets sharper or is made at higher
speeds.
39
U8HG10E0.book Page 40 Tuesday, May 18, 2010 5:39 PM
Operation
Improper riding techniques such as abrupt
throttle changes, excessive braking, incorrect
body movements, or too much speed for the
sharpness of the turn may cause the snowmobile to tip.
If your snowmobile begins to tip while turning,
lean more into the turn to regain balance. If
necessary, gradually let off on the throttle or
steer to the outside of the turn.
Remember:
Avoid higher speeds until you are thoroughly
familiar with the operation of your snowmobile.
Riding uphill
EWS00231
WARNING
Operation on slopes can lead to loss of
control if proper techniques are not used.
Follow these instructions to reduce your
risk of an accident. Do not try steeper or
more difficult inclines until you have developed your skill on gentle slopes.
You should practice first on gentle slopes. Try
more difficult climbs only after you have developed your skill. As you approach a hill, accelerate before you start the climb, and then
reduce the throttle to prevent track slippage. It
is also important to keep your weight on the
uphill side at all times. On climbs straight up
the hill, this can be accomplished by leaning
forward and, on steeper inclines, standing on
the running boards and leaning forward over
the handlebar. (Also see “Traversing a
slope”.)
40
Slow down as you reach the crest of the hill,
and be prepared to react to obstacles, sharp
drops, or other vehicles or people which may
be on the other side. If you are unable to continue up a hill, do not spin the track. Stop the
engine and set the parking brake. Then pull
the rear of the snowmobile around to point the
snowmobile back down the hill. When the
snowmobile is pointed downhill, mount your
snowmobile from the uphill side. Restart the
engine, release the parking brake, and descend the hill.
Riding downhill
EWS00240
WARNING
Use extra caution when applying the brake
during a descent. Excessive braking will
cause the drive track to lock, causing a
loss of control.
When riding downhill, keep speed to a minimum. It is important to apply just enough
throttle to keep the clutch engaged while descending the hill. This will allow you to use engine compression to help slow the
snowmobile, and to keep the snowmobile
from rolling freely down the hill. Also apply the
brake frequently, with light pressure.
U8HG10E0.book Page 41 Tuesday, May 18, 2010 5:39 PM
Operation
Traversing a slope
EWS00251
WARNING
Driving across the face of a slope (“sidehilling”) can lead to overturn or loss of
control if proper techniques are not used.
Follow these instructions to reduce your
risk of an accident. Do not try steeper or
more difficult inclines until you have developed your skill on gentle slopes.
Traversing a slope requires you to properly
position your weight to maintain proper balance. As you travel across the slope, lean
your body to position your weight towards the
uphill side. A recommended riding position is
to kneel with the knee of your downhill leg on
the seat and the foot of your uphill leg on the
running board. This position will make it easier for you to shift your body weight as needed.
Snow and ice are slippery, so be prepared for
the possibility that your snowmobile could begin to slip sideways on the slope. If this happens, steer in the direction of the slide if there
are no obstacles in your path. As you regain
proper balance, gradually steer again in the
direction you wish to travel.
If your snowmobile starts to tip, steer down
the hill to regain balance. WARNING! If you
are unable to maintain correct balance,
and your snowmobile is going to tip over,
dismount your snowmobile immediately
on the uphill side to avoid being hit or
caught under the snowmobile as it tips
over. [EWS00261]
Ice or icy surface
EWS00270
WARNING
When you have to operate on ice or icy
surfaces, drive slowly and cautiously.
Avoid accelerating, turning, and braking
rapidly. Steering is minimal and uncontrolled spins are an ever-present danger.
Operating on ice or icy surfaces can be very
dangerous. Traction for turning, stopping, and
starting is much less than that on snow.
Hard-packed snow
It can be more difficult to negotiate on hardpacked snow as both the skis and drive track
do not have as much traction as when the
snowmobile is operated on fresh snow. Avoid
rapid acceleration, turning, and braking.
Operation on surfaces other than
snow or ice
Operation of your snowmobile on surfaces
other than snow or ice should be avoided. Operation under such conditions will damage or
result in rapid wear of the ski runners, drive
track, slide runners, and drive sprockets. Operation of the snowmobile on the following
surfaces should be avoided at all times:
● Dirt
41
U8HG10E0.book Page 42 Tuesday, May 18, 2010 5:39 PM
Operation
Sand
Rocks
● Grass
● Bare pavement
Other surfaces that should be avoided for the
sake of drive track and slide runner life are:
● Glare ice surfaces
● Snow mixed with a lot of dirt and sand
All of the above surfaces have one thing in
common in regard to drive track and slide runners: little or no lubricating ability. Drive track
and all slide rail systems require lubrication
(snow or water) between the slide runners
and the slide metal. In the absence of lubrication, the slide runners will rapidly wear and in
severe cases, literally melt away, and the
drive track will be subject to damage or failure.
Also traction aids such as studs, cleats, etc.,
may cause further track damage or failure.
●
●
EWS00280
WARNING
Drive track damage or failure could result
in loss of braking ability and snowmobile
control, which could cause an accident.
● Always check the drive track for damage
or maladjustment before operating the
snowmobile.
● Do not operate the snowmobile if you
find damage to the drive track.
ECS00350
NOTICE
Ride on fresh snow frequently. Operating
on ice or hard-packed snow will rapidly
wear the slide runners.
ESU11350
Maximizing drive track life
Recommendations
Track tension
During initial break-in, the new drive track will
tend to stretch quickly as the track settles. Be
sure to correct the track tension and align-
42
ment frequently. (See page 69 for adjustment
procedures.) A loose track can slip (ratchet),
derail or catch on suspension parts causing
severe damage. Do not overtighten the drive
track, otherwise it may increase the friction
between the track and the slide runners, resulting in the rapid wear of both components.
Also, this may put an excessive load on the
suspension components, resulting in component failure.
Marginal snow
The drive track and the slide runners are lubricated and cooled by snow and water. To prevent the drive track and slide runners from
overheating, avoid sustained high-speed usage in areas such as icy trails, frozen lakes
and rivers that have minimal snow coverage.
An overheated track will be weakened internally, which may cause failure or damage.
Off-trail riding
Avoid off-trail riding until there is sufficient
snow coverage. It generally takes several feet
of snow to provide a good overall base to
properly cover debris, such as rocks, logs,
etc. If snow coverage is not sufficient, stay on
trails to avoid impact damage to the drive
track.
Studded track
In general, track life will be shortened when
studs are installed. Drilling stud holes into the
drive track will cut the internal fibers, which
weakens the track. Avoid spinning the drive
track. Studs may catch on an object and pull
out of the track, leaving tears and damage
around the already weakened area. To minimize possible damage, consult your stud
manufacturer for installation and stud pattern
recommendations.
Yamaha does not recommend track studding.

Transporting
When transporting your snowmobile on a trailer or in a truck, observe the following recommendations to help protect it from damage:
● If transporting the snowmobile in an open
trailer or truck, put a tight fitting cover on the
snowmobile. A cover specifically designed
for your snowmobile is best. This will help
keep foreign objects out of the cooling
vents, and also help protect the snowmobile against damage from debris on the
road.
● If transporting the snowmobile in an open
trailer or truck in areas where road salt is
used, coat metal suspension surfaces lightly with oil or another protectant. This will
help protect against corrosion. Be sure to
clean the snowmobile when you get to your
destination to remove any corrosive salts.

Checking the spark plugs
The spark plugs are important engine components and are easy to inspect. The condition
of the spark plugs can indicate the condition of
the engine.
Check the coloration on the white porcelain
insulator around the center electrode. The
ideal coloration at this point is a medium-tolight tan color for a snowmobile that is being
ridden normally. If any spark plug shows a
distinctly different color, there could be something wrong with the engine. For example, a
very white center electrode porcelain color
could indicate an intake track air leak or carburetion problem for that cylinder. Do not at-

Periodic maintenance and adjustment
tempt to diagnose such problems yourself.
Instead, take the snowmobile to a Yamaha
dealer for inspection and possible repairs.
You should periodically remove and inspect
the spark plugs because heat and deposits
will cause any spark plug to slowly break
down and erode. Consult a Yamaha dealer
before changing to a different type of spark
plug.

1. Spark plug gap
2. Spark plug reach
Before installing any spark plug, measure the
spark plug gap with a wire thickness gauge
and adjust to specification.
EWS00710
WARNING
Be sure to use the specified spark plug
and spark plug cap. Otherwise, the
T.O.R.S. may not work properly.
Spark plugs are produced in several different
thread lengths. The thread length or reach is
the distance from the spark plug gasket seat
to the end of the threaded portion. If the reach
is too long, overheating and engine damage
may result. If the reach is too short, spark plug
fouling and poor performance may result. Also, if the reach is too short, carbon will form on
the exposed threads resulting in combustion
chamber hot spots and thread damage. Always use a spark plug with the specified
reach.
Spark plug gap:
0.7–0.8 mm (0.028–0.031 in)
When installing the spark plug, always clean
the gasket surface. Wipe off any grime from
the threads and tighten the spark plug to the
specified torque.
Spark plug tightening torque:
13 Nm (1.3 m·kgf, 9.4 ft·lbf)

High-altitude settings
Operating at high altitude reduces the performance of a gasoline engine about 3% for every 305 m (1000 ft) of elevation. This is
because there is less air as altitude increases.
Less air means less oxygen available for
combustion.
Your snowmobile utilizes an electronic fuel injection system that delivers the optimal air/fuel ratio required by the engine. Therefore, the
fuel injection system does not need to be adjusted, even for operation at high altitude.
Remember:
Less air at higher altitude means there is less
horsepower available, even with the optimal
air/fuel ratio. Expect acceleration and top
speed to be reduced at higher altitudes.
To overcome operating with less power at
high altitudes, your snowmobile may also require different settings for the drive chain
gears and V-belt clutch to avoid poor performance and rapid wear. If you plan to operate
your snowmobile at an altitude different from
the area where you bought it, be sure to consult a Yamaha dealer. The dealer can tell you
56
The valve clearance changes with use, resulting in improper air-fuel mixture and/or engine
noise. To prevent this from occurring, the
valve clearance must be adjusted by a
Yamaha dealer at the intervals specified in
the periodic maintenance chart.

Storage
ESU12433
Long-term storage requires some preventive
procedures to guard against deterioration.
marks. If the windshield is scratched,
use a quality plastic polishing compound after washing.
Cleaning
Lubrication
Thoroughly clean the snowmobile, inside and
out, to remove the corrosive salts and acids
that can accumulate. Use Yamaha Mud,
Grease, and Engine Cleaner, or an equivalent
product, to loosen mud, grease, and grime.
Wash with mild soap, then rinse and dry completely.
Lubricate moving parts, suspension linkage,
and pivot points. Use the grease or lubricant
specified in the MAINTENANCE section, or
Yamaha Lube-Zall general-purpose lubricant.
Proper lubrication fights corrosion while it reduces friction.
ECS00870
Add Yamaha Fuel Stabilizer and Conditioner,
or an equivalent stabilizer, to the fuel tank to
help prevent fuel oxidation and gum and varnish deposits, and to inhibit corrosion in the
fuel system and injectors. In areas where oxygenated fuel (gasohol) is used, consult a
Yamaha dealer.
NOTICE
●
●
●
●
Improper cleaning can damage plastic
parts such as shroud, covers, windshields, headlight lenses, meter lenses,
etc. Use only a soft, clean cloth or
sponge with mild detergent and water to
clean plastic.
Do not use any harsh chemical products
on plastic parts. Be sure to avoid using
cloths or sponges which have been in
contact with strong or abrasive cleaning
products, solvent or thinner, fuel (gasoline), rust removers or inhibitors, brake
fluid, antifreeze or electrolyte.
Do not use high-pressure washers or
steam-jet cleaners since they cause water seepage and deterioration in the following areas: seals (of the slide rail
suspension, front suspension and
brakes), electric components (couplers,
connectors, instruments, switches and
lights), breather hoses and vents.
For snowmobiles equipped with a windshield: Do not use strong cleaners or
hard sponges as they will cause dulling
or scratching. Some cleaning compounds for plastic may leave scratches
on the windshield. Test the product on a
small hidden part of the windshield to
make sure that it does not leave any
86
Fuel system
Engine
Proper storage of the engine is essential to
prevent costly rust and corrosion damage to
internal engine components. This is more important in areas where oxygenated fuel (gasohol) is used, because the alcohol content in
the fuel increases the chance for water to enter the engine. Use Yamaha Stor-Rite Engine
Fogging Oil, or an equivalent fogging oil, to
protect both the combustion chamber and
crankshaft from corrosion. An alternate method is to remove the intake silencer and squirt
oil into the throttle bodies while the engine is
running. NOTICE: Do not simply start the
engine when in storage, starting the engine occasionally during the storage period can cause more harm than good.
Moisture and acids form during combustion which can actually increase the
chance for corrosion damage during the
storage period. [ECS00681]
U8HG10E0.book Page 87 Tuesday, May 18, 2010 5:39 PM
Storage
Surface protection
Apply a coat of wax to painted surfaces. Apply
suitable protectants to the exterior of the engine, drive track, and to other metal, plastic,
and rubber parts.
Battery
For peak performance, it is recommended
that you have your snowmobile checked and
tuned by a Yamaha dealer. The dealer has
the experience and training to help you get
the maximum performance and use out of
your Yamaha snowmobile.
Remove the battery from the snowmobile.
Store it in a cool, dry place that is above 0 °C
(32 °F), but less than 30 °C (90 °F). Check the
condition of the battery once a month, and
charge it as necessary. NOTICE: Always
keep the battery charged. Storing a discharged battery can cause permanent battery damage. [ECS00691]
Drive track
Loosen the drive track and block up the chassis so that the track is suspended above the
ground.
V-belt
Remove the V-belt and store separately.
Storage
Store the snowmobile in a dry, well-ventilated
place out of direct sunlight. Put a fabric cover
over the snowmobile, preferably one that is
designed for it. Do not use a plastic or vinyl
cover—condensation could be trapped underneath which could increase the chances of
rusting.
Returning to service after storage
When returning your snowmobile to service,
install the V-belt and battery and adjust the
drive track.
Remove the spark plugs and clean or replace
them if necessary. Perform all other pre-operation and seasonal maintenance checks listed in the periodic maintenance chart.
TIP
Before installing the battery, have a Yamaha
dealer inspect and fully charge it.
