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.

The short time
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 fa-
miliar 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 33 to start the engine. Once the
engine has warmed up, you are ready to begin riding your snowmobile.
To start out and accelerate

With the engine idling, release the park-
ing brake.

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.

Operation
EWS00220
WWARNING
• 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
trol,
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.
con-
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
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
celerate 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

Operation on surfaces other than snow or ice
Operation of your snowmobile on surfaces
other
than
snow or ice should be avoided. Op-

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

EWARNING
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.

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 65 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
cated 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,
lubri-
37
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 stud-
ding.

Strap (RX10MT / RX10MTA)
The strap should be used only by experienced
operators to assist them when traverse (sidehill) riding.
• 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.

• 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

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

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,
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.

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
el 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
sult a Yamaha dealer. The dealer can tell you
if there are any changes necessary for the altitude where you plan to ride.

Discharged battery
If the battery is discharged, the engine can be
started using a fully-charged 12-volt battery
and jumper cables. Two connecting leads
have been provided for jump-starting the
snowmobile. Due to the rubber engine mounting,
the snowmobile frame is not a suitable
grounding point for jump-starting the engine.
EWS00570
• Connect the jumper cables only to the
connecting lead terminals. Do not
connect them to the frame or any wire or
other lead.
• When connecting the jumper cables, do
not contact the jumper cables or
connecting lead terminals to each other or
to the frame or any metal part of the
snowmobile. This can cause electrical
system damage or A FIRE HAZARD.
• Be sure to pull the lead covers back over
the terminals completely. If the terminals are exposed, they could come into
contact with the frame or a metal part of
the snowmobile and this can cause electrical system damage or A FIRE HAZARD.
ECS00650
CAUTION:
Use the connecting leads to jump-start the
snowmobile only. Do not use the connecting leads for any other purpose.

Storage
ESU12430
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,
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.
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.
and Engine Cleaner, or an equivalent
ECS00680
CAUTION:
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 actual-
ly 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
wWARNING
• 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 discon-
nect 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
(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. Stor-
ing a discharged battery can cause permanent battery damage.
cool,
dry place that is above 0 °C
79
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.
