ESU10183
As the vehicle’s owner, you are responsiblefor the safe and proper operation of yoursnowmobile. When you ride your snowmo-bile, you must know and use the following foryour safety. Severe injury or death may resultif 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 operatingcontrols and their function. Consult aYamaha dealer about any control or func-tion you do not understand.
� Wear protective clothing. Wear an ap-proved helmet, and a face shield or gog-gles. Also, wear a good quality snowmobilesuit, boots, and a pair of gloves or mittensthat will permit use of your thumbs and fin-gers for operation of the controls.
� Do not operate the snowmobile after orwhile drinking alcohol or taking drugs. Yourability to operate the snowmobile is re-duced 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 isin safe operating condition. Failure to in-spect or maintain the vehicle properly in-creases the possibility of an accident orequipment damage. See page 30 for a listof pre-operation checks.
� Apply the parking brake before starting theengine. Never drive the snowmobile withthe parking brake applied. This may over-heat the brake disc and reduce braking abil-ity.
While using your snowmobile� This snowmobile was not manufactured for
use on public streets, roads, or highways.Such use is prohibited by law, and youcould collide with another vehicle.
� This snowmobile is designed to carry theOPERATOR ONLY. Passengers are pro-hibited. Carrying a passenger can causeloss of control.
� Be careful where you ride. There may beobstacles hidden beneath the snow. Stayon established trails to minimize your expo-sure to hazards. Ride slowly and cautiouslywhen you ride off of established trails. Hit-ting a rock or stump, or running into wirescould cause an accident and injury.
� This snowmobile is not designed for use onsurfaces other than snow or ice. Use on dirt,sand, grass, rocks, or bare pavement maycause loss of control and may damage thesnowmobile.
� Always ride with other snowmobilers whengoing on a ride. You may need help if yourun out of fuel, have an accident, or damageyour snowmobile.

� Many surfaces such as ice and hardpackedsnow require much longer stopping distanc-es. Be alert, plan ahead and begin deceler-ating early. The best braking method onmost surfaces is to release the throttle andapply the brake gently—not suddenly.
Avoid carbon monoxide poisoningAll engine exhaust contains carbon monox-ide, a deadly gas. Breathing carbon monoxidecan cause headaches, dizziness, drowsiness,nausea, confusion, and eventually death.Carbon monoxide is a colorless, odorless,tasteless gas which may be present even ifyou do not see or smell any engine exhaust.Deadly levels of carbon monoxide can collectrapidly and you can quickly be overcome andbe unable to save yourself. Also, deadly lev-els of carbon monoxide can linger for hours ordays in enclosed or poorly-ventilated areas. Ifyou experience any symptoms of carbonmonoxide poisoning, leave the area immedi-ately, get fresh air, and SEEK MEDICALTREATMENT.� Do not run the engine indoors. Even if you
try to ventilate engine exhaust with fans oropen windows and doors, carbon monoxidecan rapidly reach dangerous levels.
� Do not run the engine in poorly ventilated orpartially enclosed areas such as barns, ga-rages, or carports.
� Do not run the engine outdoors where en-gine exhaust can be drawn into a buildingthrough openings such as windows anddoors.
Genuine Yamaha AccessoriesChoosing accessories for your snowmobile isan important decision. Genuine Yamaha Ac-cessories, which are available only from aYamaha dealer, have been designed, tested,and approved by Yamaha for use on yoursnowmobile. Many companies with no con-nection to Yamaha manufacture parts and ac-
cessories or offer other modifications forYamaha vehicles. Yamaha is not in a positionto test the products that these aftermarketcompanies produce. Therefore, Yamaha canneither endorse nor recommend the use ofaccessories not sold by Yamaha or modifica-tions not specifically recommended byYamaha, even if sold and installed by aYamaha dealer.Maintenance and storage� When laying the snowmobile on its side for
maintenance, use a suitable stand to keepit in a stable and level position.
� Do not leave the snowmobile on its left sidefor an extended period of time. Fuel mayleak out from the fuel breather hose.
� Do not allow anyone to stand behind thesnowmobile when starting, inspecting, oradjusting the snowmobile. A broken track,track fittings, or debris thrown by the trackcould be dangerous to the operator or by-standers.
� Modifications made to the snowmobile notapproved by Yamaha, or the removal oforiginal equipment may render your snow-mobile unsafe for use, which may cause se-vere personal injury. Modifications mayalso make the snowmobile illegal to use.
� Never store the snowmobile with fuel in thefuel tank inside a building where ignitionsources are present such as hot water andspace heaters, an open flame, sparks,clothes dryers, and the like. Allow the en-gine to cool off before storing the snowmo-bile in an enclosed space.

Suspension The suspension can be adjusted to suit riderpreference. Softer settings, for example, mayprovide greater rider comfort, while harder
settings may allow more precise handling andcontrol over certain types of terrain or ridingconditions.If you are not familiar with suspension adjust-ments, have a Yamaha dealer make theseadjustments.
WARNINGEWS00151
Read and understand the following infor-mation before handling shock absorbersthat contain highly pressurized nitrogengas.� 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 dueto excessive gas pressure.
� Do not deform or damage the cylindersin any way. Cylinder damage will resultin poor damping performance.
� Do not dispose of a damaged or wornout shock absorber yourself. Take theshock absorber to a Yamaha dealer forany service.

Riding your snowmobile Getting to know your snowmobile
WARNINGEWS00211
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 difficultmaneuvers until you have become thor-oughly familiar with your snowmobileand all of its controls.
A snowmobile is a rider active vehicle, andyour riding position and your balance are thetwo basic factors of maneuvering your snow-mobile.Riding your snowmobile requires skills ac-quired through practice over a period of time.Take the time to learn the basic techniqueswell before attempting more difficult maneu-vers.Riding your new snowmobile can be a veryenjoyable activity, providing you with hours ofpleasure. However, it is essential to familiar-ize yourself with the operation of the snowmo-bile to achieve the skill necessary to enjoyriding safely. Before operating the snowmo-bile, read this Owner’s Manual completelyand understand the operation of the controls.Pay particular attention to the safety informa-tion on page 3.Please read all warning and notice labels onyour snowmobile. Also, read the Snowmobil-er’s Safety Handbook that is supplied withyour snowmobile.Learning to ride your snowmobileBefore you ride, always perform the pre-oper-ation checks listed on page 30. The short timespent checking the condition of the snowmo-bile will be rewarded with added safety and amore reliable snowmobile. Always wear theproper clothing for both warmth and to helpprotect you from injury if an accident occurs.Become familiar with operating your snowmo-bile at low speeds, even if you are an experi-enced rider. Do not attempt to operate atmaximum performance until you are totally fa-miliar with the snowmobile’s handling andperformance characteristics.

The beginning operator should select a largeflat area to become familiar with the snowmo-bile. Make sure that this area is free of obsta-cles and other traffic. You should practicecontrol of the throttle and brake, and masterturning techniques in this area before tryingmore difficult terrain.Set the parking brake and follow the instruc-tions on page 32 to start the engine. Once theengine has warmed up, you are ready to be-gin riding your snowmobile.To start out and accelerate1. With the engine idling, release the park-
ing brake.2. Apply the throttle slowly and smoothly.
The V-belt clutch will engage and you willstart to accelerate. WARNING! Do notallow anyone to stand behind thesnowmobile when starting the engine.A broken track, track fittings, or debristhrown by the track could be danger-ous to bystanders. [EWS00690]
Braking
WARNINGEWS00220
� Many surfaces such as ice and hard-packed snow require much longer stop-ping distances. Be alert, plan ahead, andbegin decelerating early.
� Improper use of the brake can cause thedrive track to lose traction, reduce con-trol, and increase the possibility of anaccident.
When slowing down or stopping, release thethrottle and apply the brake gently—not sud-denly.TurningFor most snow surfaces, “body English” is thekey to turning.
As you approach a curve, slow down and be-gin to turn the handlebar in the desired direc-tion. As you do so, put your weight on therunning board to the inside of the turn andlean your upper body into the turn.
This procedure should be practiced at lowspeeds many times, in a large flat area with noobstacles. Once you have learned this tech-nique, you should be able to perform it at high-er speeds or in tighter curves. Lean more asthe turn gets sharper or is made at higherspeeds.Improper riding techniques such as abruptthrottle changes, excessive braking, incorrectbody movements, or too much speed for thesharpness of the turn may cause the snow-mobile to tip.If your snowmobile begins to tip while turning,lean more into the turn to regain balance. Ifnecessary, gradually let off on the throttle orsteer to the outside of the turn.Remember:Avoid higher speeds until you are thoroughlyfamiliar with the operation of your snowmo-bile.Riding uphill

risk of an accident. Do not try steeper ormore difficult inclines until you have de-veloped your skill on gentle slopes.
You should practice first on gentle slopes. Trymore difficult climbs only after you have de-veloped your skill. As you approach a hill, ac-celerate before you start the climb, and thenreduce the throttle to prevent track slippage. Itis also important to keep your weight on theuphill side at all times. On climbs straight upthe hill, this can be accomplished by leaningforward and, on steeper inclines, standing onthe running boards and leaning forward overthe handlebar. (Also see “Traversing aslope”.)
Slow down as you reach the crest of the hill,and be prepared to react to obstacles, sharpdrops, or other vehicles or people which maybe on the other side. If you are unable to con-tinue up a hill, do not spin the track. Stop theengine and set the parking brake. Then pullthe rear of the snowmobile around to point thesnowmobile back down the hill. When thesnowmobile is pointed downhill, mount yoursnowmobile from the uphill side. Restart theengine, release the parking brake, and de-scend the hill.
Riding downhill
WARNINGEWS00240
Use extra caution when applying the brakeduring a descent. Excessive braking willcause the drive track to lock, causing aloss of control.
When riding downhill, keep speed to a mini-mum. It is important to apply just enoughthrottle to keep the clutch engaged while de-scending the hill. This will allow you to use en-gine compression to help slow thesnowmobile, and to keep the snowmobilefrom rolling freely down the hill. Also apply thebrake frequently, with light pressure.
Traversing a slope
WARNINGEWS00251
Driving across the face of a slope (“side-hilling”) can lead to overturn or loss ofcontrol if proper techniques are not used.Follow these instructions to reduce yourrisk of an accident. Do not try steeper ormore difficult inclines until you have de-veloped your skill on gentle slopes.
Traversing a slope requires you to properlyposition your weight to maintain proper bal-ance. As you travel across the slope, leanyour body to position your weight towards theuphill side. A recommended riding position isto kneel with the knee of your downhill leg on

36
the seat and the foot of your uphill leg on therunning board. This position will make it easi-er for you to shift your body weight as needed.
Snow and ice are slippery, so be prepared forthe possibility that your snowmobile could be-gin to slip sideways on the slope. If this hap-pens, steer in the direction of the slide if thereare no obstacles in your path. As you regainproper balance, gradually steer again in thedirection you wish to travel.If your snowmobile starts to tip, steer downthe hill to regain balance. WARNING! If youare unable to maintain correct balance,and your snowmobile is going to tip over,dismount your snowmobile immediatelyon the uphill side to avoid being hit orcaught under the snowmobile as it tipsover. [EWS00261]
Ice or icy surface
WARNINGEWS00270
When you have to operate on ice or icysurfaces, drive slowly and cautiously.Avoid accelerating, turning, and brakingrapidly. Steering is minimal and uncon-trolled spins are an ever-present danger.
Operating on ice or icy surfaces can be verydangerous. Traction for turning, stopping, andstarting is much less than that on snow.
Hard-packed snowIt can be more difficult to negotiate on hard-packed snow as both the skis and drive trackdo not have as much traction as when thesnowmobile is operated on fresh snow. Avoidrapid acceleration, turning, and braking.Operation on surfaces other than snow or iceOperation of your snowmobile on surfacesother than snow or ice should be avoided. Op-eration under such conditions will damage orresult in rapid wear of the ski runners, drivetrack, slide runners, and drive sprockets. Op-eration of the snowmobile on the followingsurfaces should be avoided at all times:� Dirt� Sand� Rocks� Grass� Bare pavementOther surfaces that should be avoided for thesake of drive track and slide runner life are:� Glare ice surfaces� Snow mixed with a lot of dirt and sandAll of the above surfaces have one thing incommon in regard to drive track and slide run-ners: little or no lubricating ability. Drive trackand all slide rail systems require lubrication(snow or water) between the slide runnersand the slide metal. In the absence of lubrica-tion, the slide runners will rapidly wear and insevere cases, literally melt away, and thedrive track will be subject to damage or failure.Also traction aids such as studs, cleats, etc.,may cause further track damage or failure.
WARNINGEWS00280

Besure to correct the track tension and align-ment frequently. (See page 63 for adjustmentprocedures.) A loose track can slip (ratchet),derail or catch on suspension parts causingsevere damage. Do not overtighten the drivetrack, otherwise it may increase the frictionbetween the track and the slide runners, re-sulting in the rapid wear of both components.Also, this may put an excessive load on thesuspension components, resulting in compo-nent failure.Marginal snowThe drive track and the slide runners are lubri-cated and cooled by snow and water. To pre-vent the drive track and slide runners fromoverheating, avoid sustained high-speed us-age in areas such as icy trails, frozen lakesand rivers that have minimal snow coverage.An overheated track will be weakened inter-nally, which may cause failure or damage.Off-trail ridingAvoid off-trail riding until there is sufficientsnow coverage. It generally takes several feetof snow to provide a good overall base toproperly cover debris, such as rocks, logs,
etc. If snow coverage is not sufficient, stay ontrails to avoid impact damage to the drivetrack.Studded trackIn general, track life will be shortened whenstuds are installed. Drilling stud holes into thedrive track will cut the internal fibers, whichweakens the track. Avoid spinning the drivetrack. Studs may catch on an object and pullout of the track, leaving tears and damagearound the already weakened area. To mini-mize possible damage, consult your studmanufacturer for installation and stud patternrecommendations.Yamaha does not recommend track stud-ding.ESU13220

Checking the spark plugs The spark plug is an important engine compo-nent and is easy to inspect. The condition ofthe spark plug can indicate the condition ofthe engine.Check the coloration on the white porcelaininsulator around the center electrode. Theideal coloration at this point is a medium to alight tan color for a snowmobile that is beingridden normally. If a spark plug shows a dis-tinctly different color, there could be some-thing wrong with the engine. For example, avery white center electrode porcelain colorcould indicate an intake track air leak or car-buretion problem for that cylinder. Do not at-tempt to diagnose such problems yourself.Instead, take the snowmobile to a Yamahadealer for inspection and possible repairs.You should periodically remove and inspectthe spark plug because heat and deposits willcause a spark plug to slowly break down anderode. Consult a Yamaha dealer beforechanging to a different type of spark plug.

High-altitude settings Operating at high altitude reduces the perfor-mance of a gasoline engine about 3% for ev-ery 305 m (1000 ft) of elevation. This isbecause there is less air as altitude increases.Less air means less oxygen available forcombustion.Your snowmobile utilizes an electronic fuel in-jection system that delivers the optimal air/fu-el ratio required by the engine. Therefore, thefuel injection system does not need to be ad-justed, even for operation at high altitude.Remember:Less air at higher altitude means there is lesshorsepower available, even with the optimalair/fuel ratio. Expect acceleration and topspeed to be reduced at higher altitudes.To overcome operating with less power athigh altitudes, your snowmobile may also re-quire different settings for the drive chaingears and V-belt clutch to avoid poor perfor-mance and rapid wear. If you plan to operateyour snowmobile at an altitude different fromthe area where you bought it, be sure to con-sult a Yamaha dealer. The dealer can tell youif there are any changes necessary for the al-titude where you plan to ride. NOTICE: Thedrive chain gears and V-belt clutch shouldbe adjusted when operating above a highaltitude of 900 m (3000 ft). Consult aYamaha dealer. [ECS00431]

WARNINGEWS00411
When installing a new V-belt, make surethat it is positioned properly. Otherwise,the V-belt clutch engagement speed will
be changed and the snowmobile maymove unexpectedly when the engine isstarted, which could cause an accident.
NOTICEECS00510
As the V-belt wears, adjustment may benecessary. To ensure proper clutch per-formance, the V-belt position should beadjusted by adding a spacer on each ad-justing bolt when the V-belt positionreaches 1.5 mm (0.06 in) below the edge ofthe secondary sheave assembly.Have a Yamaha dealer make this adjust-ment.

ESU12433
Long-term storage requires some preventiveprocedures to guard against deterioration.CleaningThoroughly clean the snowmobile, inside andout, to remove the corrosive salts and acidsthat can accumulate. Use Yamaha Mud,Grease, and Engine Cleaner, or an equivalentproduct, to loosen mud, grease, and grime.Wash with mild soap, then rinse and dry com-pletely.
NOTICEECS00870
� Improper cleaning can damage plasticparts such as shroud, covers, wind-shields, headlight lenses, meter lenses,etc. Use only a soft, clean cloth orsponge with mild detergent and water toclean plastic.
� Do not use any harsh chemical productson plastic parts. Be sure to avoid usingcloths or sponges which have been incontact with strong or abrasive cleaningproducts, solvent or thinner, fuel (gaso-line), rust removers or inhibitors, brakefluid, antifreeze or electrolyte.
� Do not use high-pressure washers orsteam-jet cleaners since they cause wa-ter seepage and deterioration in the fol-lowing areas: seals (of the slide railsuspension, front suspension andbrakes), electric components (couplers,connectors, instruments, switches andlights), breather hoses and vents.
� For snowmobiles equipped with a wind-shield: Do not use strong cleaners orhard sponges as they will cause dullingor scratching. Some cleaning com-pounds for plastic may leave scratcheson the windshield. Test the product on asmall hidden part of the windshield tomake sure that it does not leave any
marks. If the windshield is scratched,use a quality plastic polishing com-pound after washing.
LubricationLubricate moving parts, suspension linkage,and pivot points. Use the grease or lubricantspecified in the MAINTENANCE section, orYamaha Lube-Zall general-purpose lubricant.Proper lubrication fights corrosion while it re-duces friction.Fuel systemAdd Yamaha Fuel Stabilizer and Conditioner,or an equivalent stabilizer, to the fuel tank tohelp prevent fuel oxidation and gum and var-nish deposits, and to inhibit corrosion in thefuel system and injectors. In areas where ox-ygenated fuel (gasohol) is used, consult aYamaha dealer.EngineProper storage of the engine is essential toprevent costly rust and corrosion damage tointernal engine components. This is more im-portant in areas where oxygenated fuel (gas-ohol) is used, because the alcohol content inthe fuel increases the chance for water to en-ter the engine. Use Yamaha Stor-Rite EngineFogging Oil, or an equivalent fogging oil, toprotect both the combustion chamber andcrankshaft from corrosion. An alternate meth-od is to remove the intake silencer and squirtoil into the throttle bodies while the engine isrunning. NOTICE: Do not simply start theengine when in storage, starting the en-gine occasionally during the storage peri-od can cause more harm than good.Moisture and acids form during combus-tion which can actually increase thechance for corrosion damage during thestorage period.

Check thecondition of the battery once a month, andcharge it as necessary. NOTICE: Alwayskeep the battery charged. Storing a dis-charged battery can cause permanent bat-tery damage. [ECS00691]
Drive trackLoosen the drive track and block up the chas-sis so that the track is suspended above theground.V-beltRemove the V-belt and store separately.StorageStore the snowmobile in a dry, well-ventilatedplace out of direct sunlight. Put a fabric coverover the snowmobile, preferably one that isdesigned for it. Do not use a plastic or vinylcover—condensation could be trapped un-derneath which could increase the chances ofrusting.Returning to service after storageWhen returning your snowmobile to service,install the V-belt and battery and adjust thedrive track.Remove the spark plugs and clean or replacethem if necessary. Perform all other pre-oper-ation and seasonal maintenance checks list-ed in the periodic maintenance chart.
TIPBefore installing the battery, have a Yamahadealer inspect and fully charge it.
For peak performance, it is recommendedthat you have your snowmobile checked andtuned by a Yamaha dealer. The dealer hasthe experience and training to help you getthe maximum performance and use out ofyour Yamaha snowmobile.
