4.
Do not operate the snowmobile after
drinking alcohol or taking drugs. Your
ability to operate the snowmobile is reduced by the influence of alcohol or
drugs.
5.
For safety and proper care of the snowmobile, always perform the pre-operation
checks on page 29 before starting the engine. Check the throttle, brake, and steering for proper operation every time before
starting the engine. Make sure that the
throttle lever moves freely and it returns
to the home position when it is released.
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.
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.
Handle fuel with care; it is HIGHLY
FLAMMABLE.
● Never add fuel when the engine is running or hot. Allow the engine to cool for
several minutes after running.
● Use an approved fuel container.
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 operating

Fill the fuel tank outdoors with extreme
care. Never remove the fuel cap indoors. Never fill the fuel tank indoors.
Never refuel while smoking or in the vicinity of an open flame.
Make sure that the fuel tank cap is
closed securely after refueling. Wipe
up any spilled fuel immediately.
If you swallow some gasoline, inhale a lot
of gasoline vapor, or get some gasoline
into your eyes, see your doctor immediately. If any gasoline spills on your skin or
clothing, immediately wash your skin with
soap and water, and change your
clothes.
10. 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.
Operation
1.
Do not run the engine indoors, except
when starting the engine to transport the
snowmobile in or out of the building.
Open the outside doors; exhaust fumes
are dangerous.
2.
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.
Avoid operating on glare ice, or on snow
which has a lot of dirt or sand mixed in.
Operation under such conditions will
damage or result in rapid wear of ski runners, drive track, slide runners, and drive
sprockets.
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 hardpacked snow require much longer stopping distances. Be alert, plan ahead and

5.
Do not leave the snowmobile on its left
side for an extended period of time. Fuel
may leak out from the fuel breather hose.
Modifications made to the snowmobile
not approved by Yamaha, or the removal
of original equipment may render your
snowmobile unsafe for use that 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.
Always refer to the “STORAGE” section
on page 75 if the snowmobile is to be
stored for an extended period.

Pre-operation checks
ESU11070
The condition of a snowmobile is the owner’s responsibility. Vital components can start to deteriorate quickly and unexpectedly, even if the snowmobile remains unused (for example, as a
result of exposure to the elements). Any damage or fluid leakage could have serious consequences. Therefore, it is very important, in addition to a thorough visual inspection, to check
the following points before each ride.
NOTE:
Pre-operation checks should be made each time the snowmobile is used. Such an inspection
can be accomplished in a very short time; and the added safety it assures is more than worth
the time involved.

Riding your snowmobile
Getting to know your snowmobile
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.
Pay particular attention to the safety information on page 1.
Please read all warning and caution labels on
your snowmobile. Also, read the Snowmobiler’s Safety Handbook that is supplied with
your snowmobile.
Learning to ride your snowmobile
Before you ride, always perform the pre-operation checks listed on page 29. The short time
spent checking the condition of the snowmo-
32
bile 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 31 to start the engine. Once the
engine has warmed up, you are ready to begin riding your snowmobile.
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.
EWS00210
WARNING
The operator should always keep both
hands on the handlebar. Never put your
feet outside the running boards. Avoid
high speeds until you have become thoroughly familiar with your snowmobile and
all of its controls.
Braking
When slowing down or stopping, release the
throttle and apply the brake gently—not suddenly.
U8GD12E0.book Page 33 Tuesday, March 20, 2007 1:04 PM
Operation
EWS00220
WARNING
●
●
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.
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.
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.
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
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”.)
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
33
U8GD12E0.book Page 34 Tuesday, March 20, 2007 1:04 PM
Operation
snowmobile from the uphill side. Restart the
engine, release the parking brake, and descend the hill.
EWS00230
WARNING
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.
Side hills and steep slopes are not recommended for a novice snowmobiler.
Riding downhill
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.
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.
EWS00260
WARNING
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.
Traversing a slope
EWS00250
WARNING
Traversing slopes is not recommended for
a novice snowmobiler.
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
34
If you are unable to maintain correct balance, and your snowmobile is going to tip
over, dismount your snowmobile immediately on the uphill side.
Ice or icy surface
Operating on ice or icy surfaces can be very
dangerous. Traction for turning, stopping, and
starting is much less than that on snow.
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.
U8GD12E0.book Page 35 Tuesday, March 20, 2007 1:04 PM
Operation
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
● 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
CAUTION:
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 alignment frequently. (See page 62 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,
35
U8GD12E0.book Page 36 Tuesday, March 20, 2007 1:04 PM
Operation
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 plug is an important engine component and is easy to inspect. The condition of
the spark plug 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 to a
light tan color for a snowmobile that is being
ridden normally. If a 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 attempt 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 plug because heat and deposits will
cause a spark plug to slowly break down and
erode. Consult a Yamaha dealer before
changing to a different type of spark plug.
44
Specified spark plug:
Manufacturer:
NGK
Model:
CR9EB
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 reach:
19.0 mm (0.75 in)
1. Spark plug gap
2. Spark plug reach
Before installing any spark plug, measure the
electrode gap with a wire thickness gauge

ESU11930
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
if there are any changes necessary for the altitude where you plan to ride.
ECS00430
CAUTION:
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.
ESU11950
Valve clearance
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

Engine oil and oil filter cartridge
The engine oil level should be checked before
each use. In addition, the oil must be changed

WARNING
Do not remove the coolant reservoir 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 coolant reservoir
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.
1. “COLD LEVEL” mark
ECS00490
CAUTION:
●
To check the coolant level
1. Remove the top cover. (See page 42 for
removal procedures.)
2. Check the coolant level in the coolant recovery tank when the engine is cold. If the
coolant level is below the “COLD LEVEL”
mark, add soft water until it reaches the
“COLD LEVEL” mark. (See the following
section “Replenishing the coolant” for
more details.)
●
Hard water or salt water is harmful to the
engine parts. You may use boiled or distilled water, if soft water is not available.
Tap water can be used temporarily in an
emergency.
Bleeding the cooling system
The cooling system must be bled of air if the
coolant reservoir becomes empty, if air can be
seen in the cooling system, or if there is a
cooling system leak. Consult a Yamaha dealer.
ECS00500
CAUTION:
Operating the engine with an improperly
bled cooling system can cause overheating and severe engine damage.

Storage
ESU12430
ECS00680
CAUTION:
Long-term storage requires some preventive
procedures to guard against deterioration.
Cleaning
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.
Lubrication
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.
Do not attempt to store the snowmobile by
simply starting the engine occasionally
during the storage period. This 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.
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
EWS00610
WARNING
●
Fuel system
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.
●
●
●
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.
●
Never smoke around the battery while it
is being charged. Sparks may ignite the
hydrogen gas created by the battery.
Disconnect the negative lead first, then
the positive lead from the battery.
Connect the positive lead first, then the
negative lead to the battery when installing the battery.
Never connect the battery to or disconnect it from the snowmobile while it is
being charged. Sparks may ignite the
hydrogen gas created by the battery.
Make sure that the battery terminals are
tight.
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.
ECS00690
CAUTION:
●
Always keep the battery charged. Storing a discharged battery can cause permanent battery damage.
75
U8GD12E0.book Page 76 Tuesday, March 20, 2007 1:04 PM
Storage
●
●
To charge a sealed-type (MF) battery, a
special
(constant-voltage)
battery
charger is required. Using a conventional battery charger will damage the battery. If you do not have access to a
sealed-type (MF) battery charger, have a
Yamaha dealer charge your battery.
Do not charge the battery quickly.
Charge the battery for 10 hours at 1.2
amperes.
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.
NOTE:
Before installing the battery, have a Yamaha
dealer inspect and fully charge it.
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.
