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 func-
● tion you do not understand.
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.
● 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 increases the possibility of an accident or
equipment damage. See page 35 for a list
of pre-operation checks.
● Be careful where you ride. There may be obstacles hidden beneath the snow. Stay on established trails to minimize your exposure to hazards. Ride slowly and cautiously when you ride off of established trails. Hitting a rock or stump, or running into wires could cause an accident and injury.
● This snowmobile is not designed for use on surfaces other than snow or ice. Use on dirt, sand, grass, rocks, or bare pavement may cause loss of control and may damage the snowmobile.
● Always ride with other snowmobilers when going on a ride. You may need help if you run out of fuel, have an accident, or damage your snowmobile.
6
U8HG10E0.book Page 7 Tuesday, May 18, 2010 5:39 PM
Safety information
● 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, ga-
● rages, or carports.
Do not run the engine outdoors where engine exhaust can be drawn into a building through openings such as windows and doors.
Genuine Yamaha Accessories
Choosing accessories for your snowmobile is an important decision. Genuine Yamaha Accessories, which are available only from a
Yamaha dealer, have been designed, tested, and approved by Yamaha for use on your snowmobile. Many companies with no connection to Yamaha manufacture parts and accessories or offer other modifications for
Yamaha vehicles. Yamaha is not in a position to test the products that these aftermarket companies produce. Therefore, Yamaha can neither endorse nor recommend the use of accessories not sold by Yamaha or modifications not specifically recommended by
Yamaha, even if sold and installed by a
Yamaha dealer.
Maintenance and storage
● When laying the snowmobile on its side for maintenance, use a suitable stand to keep it in a stable and level position.
● Do not leave the snowmobile on its left side for an extended period of time. Fuel may leak out from the fuel breather hose.
● Do not allow anyone to stand behind the snowmobile when starting, inspecting, or adjusting the snowmobile. A broken track, track fittings, or debris thrown by the track could be dangerous to the operator or bystanders.
● Modifications made to the snowmobile not approved by Yamaha, or the removal of original equipment may render your snowmobile unsafe for use, which may cause severe personal injury. Modifications may also make the snowmobile illegal to use.
● Never store the snowmobile with fuel in the fuel tank inside a building where ignition sources are present such as hot water and space heaters, an open flame, sparks, clothes dryers, and the like. Allow the engine to cool off before storing the snowmobile in an enclosed space.

Throttle lever
Once the engine is running cleanly, squeezing the throttle lever will increase the engine speed and cause engagement of the drive train. Regulate the speed of the snowmobile by varying the throttle position. Because the throttle is spring-loaded, the snowmobile will decelerate, and the engine will return to idle when it is released.

WARNING
Gasoline and gasoline vapors are extremely flammable. To avoid fires and explosions and to reduce the risk of injury when refueling, follow these instructions.
Make sure there is sufficient gasoline in the tank.
1.
Before refueling, turn off the engine and be sure that nobody is on the snowmobile. Never refuel while smoking, or while in the vicinity of sparks, open flames, or other sources of ignition such as the pilot lights of water heaters and clothes dryers.
2.
Do not overfill the fuel tank. Stop filling when the fuel reaches the bottom of the filler tube. Because fuel expands when it heats up, heat from the engine or the sun can cause fuel to spill out of the fuel tank.

NOTICE
● 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 recommend-
● ed.
Make sure that snow or ice does not enter the fuel tank when refueling.
● Do not use alcohol deicers or water absorbing additives with oxygenated fuel.
● 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.
ESU14000
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.
EWS00151
WARNING
Read and understand the following information before handling shock absorbers that contain highly pressurized nitrogen gas.
● Do not tamper with or attempt to open the cylinder assemblies.
● Do not subject the shock absorbers to an open flame or other high heat source.
This may cause the unit to explode due to excessive gas pressure.
● Do not deform or damage the cylinders in any way. Cylinder damage will result in poor damping performance.
● Do not dispose of a damaged or worn out shock absorber yourself. Take the shock absorber to a Yamaha dealer for any service.
TIP
Use the special wrench included in the owner’s tool kit to make the suspension adjustments. If the tool kit for your model does not include the special wrench, the special wrench can be obtained at a Yamaha dealer.

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

Riding your snowmobile
Getting to know your snowmobile
EWS00211
WARNING
To avoid severe injury or death:
● Keep both hands on the handlebar during 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.
38
U8HG10E0.book Page 39 Tuesday, May 18, 2010 5:39 PM
Operation
Pay particular attention to the safety informa-
Please read all warning and notice 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-oper-
ation checks listed on page 35. 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 instruc-
tions on page 37 to start the engine. Once the
engine has warmed up, you are ready to begin riding your snowmobile.
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]
Braking
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.
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.
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.
39
U8HG10E0.book Page 40 Tuesday, May 18, 2010 5:39 PM
Operation
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
WARNING
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
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.
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.
40
U8HG10E0.book Page 41 Tuesday, May 18, 2010 5:39 PM
Operation
Traversing a slope
EWS00251
WARNING
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
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.
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 track, slide runners, and drive sprockets. Operation of the snowmobile on the following surfaces should be avoided at all times:
● Dirt
41
U8HG10E0.book Page 42 Tuesday, May 18, 2010 5:39 PM
Operation
● 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
NOTICE
Ride on fresh snow frequently. Operating on ice or hard-packed snow will rapidly wear the slide runners.
ESU11350
WARNING
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 align-
ment frequently. (See page 69 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 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.
1. Off
● Push down the engine stop switch to stop the engine in an emergency.

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 at-

U8HG10E0.book Page 52 Tuesday, May 18, 2010 5:39 PM
Periodic maintenance and adjustment tempt 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.
Specified spark plug:
Manufacturer:
NGK
Model:
CR9EB
EWS00710
WARNING
Be sure to use the specified spark plug and spark plug cap. Otherwise, the
T.O.R.S. may not work properly.
1. Spark plug gap
2. Spark plug reach
Before installing any spark plug, measure the spark plug gap with a wire thickness gauge and adjust to specification.
Spark plug gap:
0.7–0.8 mm (0.028–0.031 in)
When installing the spark plug, always clean the gasket surface. Wipe off any grime from the threads and tighten the spark plug to the specified torque.
Spark plug tightening torque:
13 Nm (1.3 m·kgf, 9.4 ft·lbf)
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)
ECS00382
NOTICE
Make sure that the spark plug caps are securely installed. Otherwise the spark plug caps could be damaged due to engine vibration.

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. 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.

Storage
ESU12433
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.
ECS00870
NOTICE
● 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 windshield: 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
86 marks. If the windshield is scratched, use a quality plastic polishing compound after washing.
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. NOTICE: Do not simply start the engine when in storage, starting the engine occasionally during the storage period 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.

Storage
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
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.
[ECS00691]
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.
TIP
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.

WARRANTY QUESTIONS AND
ANSWERS
Q. What costs are my responsibility during the warranty period?
A. The customer’s responsibility includes all costs of normal maintenance services, non-warranty repairs, accident and collision damages, as well as oil, spark plugs, clutch drive belts, and slide runners.
Q. What are some examples of “abnormal” strain, neglect, or abuse?
A. These terms are general and overlap each other in areas. Specific examples include: Running the machine out of oil, hitting an object submerged under snow, operation on surfaces other than snow or ice, operating the machine with a broken or damaged part which causes another part to fail, and so on. If you have any specific questions on operation or maintenance, please contact your dealer for advice.
Q. May I perform any or all of the recommended maintenance shown in the Owner’s Manual instead of having the dealer do them?
A. Yes, if you are a qualified snowmobile mechanic and follow the procedures specified in the Owner’s and
Service Manual. We do recommend, however, that items requiring special tools or equipment be done by a Yamaha snowmobile dealer.
Q. Under what conditions is the clutch not covered by warranty?
A. Clutches as well as clutch components wear with use. Normal wear is not covered under warranty such service is the customer’s responsibility. Abnormal wear is, however, covered for one (1) year from the date of purchase. Your Yamaha snowmobile dealer possesses criteria as to what constitutes abnormal wear.
Q. Will the warranty be void or canceled if I do not operate or maintain my new Yamaha exactly as specified in the Owner’s Manual?
A. No. The warranty on a new Yamaha cannot be
“voided” or “canceled.” However, if a particular failure is caused by operation or maintenance other than as shown in the Owner’s Manual, that failure may not be covered under warranty.
