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 oper-

ating 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 pro-

hibited by law, and you could collide with another

vehicle.

3. This snowmobile is designed to carry the OPERA-

TOR 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 snowmo-

bile 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.

3-2

7. Do not allow anyone to stand behind the snowmobile

when starting, inspecting, or adjusting the snowmo-

bile. 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 immedi-

ately.

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 qual-

ity snowmobile suit, boots, and a pair of gloves or mit-

tens 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.

3-3

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 sprock-

ets.

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 snow-

mobile is to be stored for an extended period.

5. Maintain or replace safety and instruction labels, as

necessary.
