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 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 6-1–6-9
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
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
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 snow-
mobile is to be stored for an extended period.
5. Maintain or replace safety and instruction labels, as
necessary.

Throttle lever
Once the engine is running cleanly, squeezing a the throttle lever 1 will increase the engine speed and cause
engagement of the drive system. 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 b.
WARNING
@
Check the throttle, brake, and steering for proper
operation before starting the engine.
@
ESU00231
Throttle override system (T.O.R.S.)
If the carburetor or throttle cable should malfunction during operation, the T.O.R.S. will operate when the throttle
lever is released.
The T.O.R.S. is designed to interrupt the ignition and
keep the engine speed between 2,800 and 3,000 r/min if
the carburetor fails to return to idle when the lever is
released.
WARNING
@
●
If the T.O.R.S. is activated, make sure that the
