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.
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.
creases the possibility of an accident or equipment damage. See page 48 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.
This snowmobile is designed to carry the
OPERATOR ONLY. Passengers are pro­hibited. Carrying a passenger can cause loss of control.
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-
16
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.
Safety information
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 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 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,
17
Safety information
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.

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.
For CANADA
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.
Do not use alcohol deicers or water ab-
sorbing additives with oxygenated fuel.

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.

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.
Operation
ECS00340
After 800 km (500 mi) of operation, the
engine oil must be changed and the oil filter cartridge replaced.
If any engine trouble should occur dur-

Riding your snowmobile

Getting to know your snowmobile
EWS00211
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.
51
Operation
WARNING
Pay particular attention to the safety informa­tion on page 16. Please read all warning and notice labels on your snowmobile. Also, read the Snowmobiler’s Safety Hand­book that is supplied with your snowmobile (for Canada).
Learning to ride your snowmobile
Before you ride, always perform the pre-oper­ation checks listed on page 48. 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 50 to start the engine. Once the engine has warmed up, you are ready to be­gin riding your snowmobile.
A broken track, track fittings, or debris thrown by the track could be danger­ous to bystanders.
[EWS00690]
Braking
EWS00220
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.
52
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 high-
er speeds or in tighter curves. Lean more as
WARNING
WARNING
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
EWS00231
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”.)
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
EWS00240
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.
53
Operation
WARNING
WARNING
Traversing a slope
EWS00251
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
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.
54
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.
EWS00280
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
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 84 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

The strap should be used only by experienced operators to assist them when traverse (side­hill) riding.
1. Strap
EWS00290
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

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 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 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.

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. 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.
EWS00390
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.
1. Radiator cap
To check the coolant level
1. Place the snowmobile on a level surface and apply the parking brake.
2. Check the coolant level in the coolant reservoir when the engine is cold. If the coolant level is below the “LOW” mark, add coolant until it reaches the “FULL” mark. (See the following section “Replen­ishing the coolant” for more details.)
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.
