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 39 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-

● 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.

Page 19

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,

Page 20

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.

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.

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.

change tripmeter and “OIL” flash alternately in the odometer display, and the tripmeter starts counting the distance traveled from that point. When this occurs, change the engine oil as soon as possible. (See page 60 for the oil change procedure.)

E LO

● The oil change tripmeter will flash only

when the snowmobile is stopped.

● To return to the previous display mode,

push the “SELECT” button. To display the oil change tripmeter again, turn the key to the off position, then back to the on position.

After changing the engine oil, reset the oil change tripmeter as follows.

To reset the oil change tripmeter (when the engine oil was changed after the oil change tripmeter appeared)

1. To display the oil change tripmeter, turn the key to the on position.

2. Push the “RESET” button for at least 1 second while the oil change tripmeter and “OIL” are flashing alternately in the odometer display. The distance traveled since the last oil change and “OIL” will flash alternately in the odometer display.

3. Push the “RESET” button for approximately 3 seconds. “00000” and “OIL” will flash alternately in the odometer display 3 times, and then the display will return to the previous display mode.

If the engine oil is changed before the oil change tripmeter appears in the display (i.e., before the periodic oil change interval has been reached), the tripmeter must be reset after the oil change for the next periodic oil change to be indicated at the correct time. In that case, reset the oil change tripmeter as follows.

Oil level/pressure warning indicator “ ”

The oil level/pressure warning indicator has two functions. The warning indicator comes on when the engine oil level is low and when the engine oil pressure is low. The functions are explained in the following sections.

Oil level warning

The warning indicator and the warning light come on when the engine oil level is low.

1. Oil level/pressure warning indicator “ ”

2. Warning light “ ”

If the warning indicator and the warning light come on, place the snowmobile on a level surface and allow it to idle for one minute. If the warning indicator and the warning light go off, the engine oil level is sufficient, however it is getting low. Add engine oil as soon as possible. If the warning indicator and the warning light do not go off, check the engine oil level in the oil tank (see page 60 for engine oil level checking procedures), and add engine oil if necessary. If the warning indicator and the warning light still remain on, have a Yamaha dealer check the snowmobile.

Oil pressure warning

The warning indicator comes on and “OP-LO” (oil pressure low) appears in the odometer display if the engine oil pressure is low when the engine is started. At the same time, the engine speed is limited to less than the clutch engagement speed until the warning indicator goes off. If the engine oil pressure remains low for one minute, the engine stops. If this occurs, have a Yamaha dealer check the snowmobile.

Read the Owner’s Manual carefully to become familiar with all controls. If there is a control or function you do not understand, ask your Yamaha dealer.

EWS00203

Failure to familiarize yourself with the controls can lead to loss of control, which could cause an accident or injury.

ESU13212

This model is equipped with:

● an engine oil pressure switch to stop the en-

gine 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.

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-

ing the engine break-in period, immediately have a Yamaha dealer check the snowmobile.

ESU12625

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.

Page 51

Operation

WARNING

Pay particular attention to the safety information on page 10. 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 39. 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 41 to start the engine. Once the engine has warmed up, you are ready to begin riding your snowmobile.

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. 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.

Page 52

Operation

WARNING

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”.)

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.

Page 53

Traversing a slope

WARNING

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.

Operation

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.

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

Page 54

Operation

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 74 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

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.

Periodic maintenance and adjustment

WARNING

ESU11452

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.

EWS00341

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.

EWS00700

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 10 for more information about carbon monoxide.

EWS00790

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.

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.

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

Storage

NOTICE

ESU12444

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.

[EWS00601]

5. Remove the spark plug caps from the spark plugs, and then install the spark plugs and the spark plug caps.

Fuel

Add a fuel 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.

Chassis

1. Lubricate all specified points with grease. (See page 78 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.

ECS00870

● 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.

Page 100

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.
