Safety information
ESU10204
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.
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 ap-
proved 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
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 in-
creases the possibility of an accident or
equipment damage. See page 30 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.
While using your snowmobile
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.
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.
Many surfaces such as ice and hard-
packed 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 eventu-
9
Page 18
Safety information
ally 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 en-
gine exhaust can be drawn into a building
through openings such as windows and
doors.
Genuine Yamaha Accessories
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
accessories 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.

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.

Riding your snowmobile
Getting to know your snowmobile
EWS00212
To avoid severe injury or death:
Keep both hands on the handlebar dur-
ing 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.

Page 42
Operation
WARNING
Pay particular attention to the safety information on page 9.
Please read all warning and notice labels on
your snowmobile.
Learning to ride your snowmobile
Before you ride, always perform the pre-operation checks listed on page 30. 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 32 to start the engine. Once the
engine has warmed up, you are ready to begin riding your snowmobile.
Braking
EWS00221
Many surfaces such as ice and hard-
packed 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. With the engine idling, release the parking brake.
2. 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.
[EWS00691]
34
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.
Page 43
Improper riding techniques such as abrupt
WARNING
WARNING
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
EWS00232
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 im portant 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”.)
Operation
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
EWS00241
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.

Page 44
Operation
WARNING
WARNING
Traversing a slope
EWS00252
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.
[EWS00262]
Ice or icy surface
EWS00271
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.
36
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

WARNING
NOTICE
track, slide runners, and drive sprockets. Operation of the snowmobile on the following
surfaces should be avoided at all times:
Dirt
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.
EWS00281
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 dam-
age or maladjustment before operating
the snowmobile.
Do not operate the snowmobile if you
find damage to the drive track.
ECS00351
ESU11351
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 alignment frequently. (See page 66 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.
Ride on fresh snow frequently. Operating
on ice or hard-packed snow will rapidly
wear the slide runners.
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

Strap
The strap should be used only by experienced operators to assist them when traverse (side-hill) riding.
1. Strap
EWS00291
Improper use of the strap on the handlebar can result in severe injury or death.
Use the strap only as an operator grip
point when needed to shift weight uphill
to maintain balance during traverse
(side-hill) riding. Only experienced operators should traverse slopes steep
enough to require strap use.
Keep the right hand on the right handle-
bar grip for steering, and grip the strap
with the left hand to shift weight uphill
for balance during traverse riding.
Ride cautiously while using the strap. Do
not accelerate or decelerate abruptly
while holding onto the strap.
Do not use the strap to lift the snowmo-
bile.
Do not use the strap as a mounting point
for cargo or accessories.

Transporting
When transporting your snowmobile on a
trailer or in a truck, observe the following recommendations to help protect it from damage:
Make sure that the fuel level in the fuel tank
is lower than the bottom of the carburetors.
Otherwise, the vibration and bumps from
the road surface could make it possible for
fuel to flow through the carburetors into the
cylinders. This can result in “hydrostatic
lock,” a condition where the engine cannot
rotate because of fuel accumulated in the
engine. Severe engine damage can result
from hydrostatic lock. When possible, the
fuel tank should be empty during transportation, especially if the trip takes longer
than 30 minutes.
39
Page 48
Operation
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 in the shroud, 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.

ESU11453
Periodic inspection, adjustment, and lubrication will keep your snowmobile in the safest and
most efficient condition possible. Safety is an obligation of the vehicle owner/operator. The
most important points of vehicle inspection, adjustment, and lubrication are explained on the
following pages.
EWS00342
Failure to properly maintain the snowmobile or performing maintenance activities incorrectly may increase your risk of injury or death during service or while using the snowmobile. If you are not familiar with snowmobile service, have a Yamaha dealer perform
service.
EWS00701
Turn off the engine when performing maintenance unless otherwise specified.
A running engine has moving parts that can catch on body parts or clothing, and elec-
trical parts that can cause shocks or fires.
Running the engine while servicing can lead to eye injury, burns, fire, or carbon mon-
oxide poisoning–possibly leading to death. See page 9 for more information about
carbon monoxide.
EWS00791
Brake discs, calipers, and linings can become very hot during use. To avoid possible
burns, let brake components cool before touching them.
Maintenance, replacement, or repair of the emission control devices and systems may
be performed by any repair establishment or individual that is certified (if applicable).
Proper periodic maintenance of your snowmobile is important in order to enjoy long, pleasurable use. Especially important are the maintenance services related to emission control.
These controls not only function to ensure cleaner air, but are also vital to proper engine operation and maximum performance. In the following periodic maintenance charts, the services
related to emission control are grouped separately. These services require specialized data,
knowledge, and equipment. Yamaha dealers are trained and equipped to perform these particular services.

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
plug.
Specified spark plug:
Manufacturer:
NGK
Model:
CR8E
EWS00711
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.

Carburetors
The carburetors are an important part of the
engine and its emission control system,
which require very sophisticated adjustment.
Therefore, carburetor adjustments should be
left to a Yamaha dealer, who has the necessary professional knowledge and experience.
ESU11942
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 can be adjusted to overcome most of the problems found in high-altitude riding. Carburetor adjustments are the
most important. Less air at high altitude
makes the air/fuel ratio too rich, which can
cause poor performance. Common problems
are hard starting, bogging, and plug fouling.
Proper carburetion adjustments will correct
the air/fuel ratio. Be sure to have a Yamaha
dealer make these adjustments.
Remember:
Less air at higher altitude means there is less
horsepower available, even with proper carburetion. 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
if there are any changes necessary for the altitude where you plan to ride. NOTICE: The
drive chain gears and V-belt clutch should
be adjusted when operating above a high
altitude of 900 m (3000 ft). Consult a
Yamaha dealer.

The coolant level should be checked before
each ride. In addition, the cooling system
must be bled at the intervals specified in the
periodic maintenance and lubrication chart.
EWS00391
Do not remove the radiator cap when the
engine is hot. Scalding hot fluid and steam
may be blown out under pressure, which
could cause serious injury.
When the engine has cooled, place a thick
rag or towel over the radiator cap, and
slowly rotate the cap counterclockwise to
the detent. This procedure allows any residual pressure to escape. When the hissing sound has stopped, press down on the
cap while turning counterclockwise and
remove it.
NOTICE: If coolant is not available,
use distilled water or soft tap water instead. Do not use hard water or salt
water since it is harmful to the engine.
If water has been used instead of
coolant, replace it with coolant as
soon as possible, otherwise the cooling system will not be protected
against frost and corrosion. If water
has been added to the coolant, have a
Yamaha dealer check the antifreeze
content of the coolant as soon as possible, otherwise the effectiveness of
the coolant will be reduced.

Storage
NOTICE
ESU12427
Long-term storage of your snowmobile will
require some preventive procedures to guard
against deterioration.
Engine
Perform the following steps to protect the
cylinders, piston rings, etc., from corrosion.
1. Remove the spark plug caps and spark
plugs.
2. Pour a teaspoonful of engine oil into
each spark plug bore.
3. Install the spark plug caps onto the spark
plugs, and then place the spark plugs on
the cylinder head so that the electrodes
are grounded. (This will limit sparking
during the next step.)
4. Turn the engine over several times with
the starter. (This will coat the cylinder
walls with oil.) WARNING! To prevent
damage or injury from sparking, make
sure to ground the spark plug electrodes while turning the engine over.
[EWS00602]
5. Remove the spark plug caps from the
spark plugs, and then install the spark
plugs and the spark plug caps.
Fuel
Drain the fuel tank and carburetor float bowls.
This will prevent fuel deposits from building
up.
Chassis
1. Lubricate all specified points with
grease. (See page 69 for detailed information about the lubrication points.)
2. Loosen the drive track and block up the
chassis so that the track is suspended
above the ground.
3. Clean the exterior of the snowmobile and
apply a rust inhibitor.
4. Store the snowmobile in a dry, well-ventilated place with a porous cover placed
over it.
5. Keep the snowmobile on a level surface
during storage or while transporting.
ECS00871
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 wind-
shield: 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
marks. If the windshield is scratched,
use a quality plastic polishing compound after washing.

Storage
TIP
Battery
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.
Before installing the battery, have a Yamaha
dealer inspect and fully charge it.

The figures quoted are emission levels and
are not necessarily safe working levels.
Whilst there is a correlation between the
emission and exposure levels, this cannot be
used reliably to determine whether or not further precautions are required. Factors that influence the actual level of exposure of workforce include the characteristics of the work
room, the other sources of noise, etc. i.e. the
number of machines and other adjacent processes, and the length of time for which an
operator is exposed to the noise. Also the
permissible exposure level can vary from
country. This information, however, will enable the user of the machine to make a better
evaluation of the hazard and risk.
