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.

SAFETY INFORMATION
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 operating
1.Read the Owner’s Manual and all labels before operating this snowmobile. Become familiar with all of the operating controls and their function. Consult a Yamaha dealer about any control or function you do not understand.
2.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.
3.This snowmobile is designed to carry the OPERATOR ONLY.
Passengers are prohibited. Carrying a passenger can cause loss of control.
4.Do not operate the snowmobile after drinking alcohol or taking drugs. Your ability to operate the snowmobile is reduced by the influence of alcohol or drugs.
5.For safety and proper care of the snowmobile, always perform the pre-operation checks on pages 6-1–6-11 before starting the engine. Check the throttle, brake, and steering for proper operation every time before starting the engine. Make sure that the throttle lever moves freely and it returns to the home position when it is released.
6.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.
3-1
E_8gg.book Page 2 Thursday, March 16, 2006 4:23 PM
7.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.
8.Handle fuel with care; it is HIGHLY FLAMMABLE.
●Never add fuel when the engine is running or hot. Allow the engine to cool for several minutes after running.
●Use an approved fuel container.
●Fill the fuel tank outdoors with extreme care. Never remove the fuel cap indoors. Never fill the fuel tank indoors.
●Never refuel while smoking or in the vicinity of an open flame.
●Make sure that the fuel tank cap is closed securely after refueling. Wipe up any spilled fuel immediately.
9.If you swallow some gasoline, inhale a lot of gasoline vapor, or get some gasoline into your eyes, see your doctor immediately. If any gasoline spills on your skin or clothing, immediately wash your skin with soap and water, and change your clothes.
10.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.
Operation
1.Do not run the engine indoors, except when starting the engine to transport the snowmobile in or out of the building. Open the outside doors; exhaust fumes are dangerous.
2.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.
3-2
E_8gg.book Page 3 Thursday, March 16, 2006 4:23 PM
3.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.
4.Avoid operating on glare ice, or on snow which has a lot of dirt or sand mixed in. Operation under such conditions will damage or result in rapid wear of ski runners, drive track, slide runners, and drive sprockets.
5.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.Many surfaces such as ice and hard-packed 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.
Maintenance and storage
1.Do not leave the snowmobile on its left side for an extended period of time. Fuel may leak out from the fuel breather hose.
2.Modifications made to the snowmobile not approved by Yamaha, or the removal of original equipment may render your snowmobile unsafe for use that may cause severe personal injury. Modifications may also make the snowmobile illegal to use.
3.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.
4.Always refer to the “STORAGE” section if the snowmobile is to be stored for an extended period.
5.Maintain or replace safety and instruction labels, as necessary.
