A Safety information

ESU10180

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
ways.

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.

high-

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 page
gine.

Check the
ing 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.

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

ning or hot. Allow the engine to cool for
several minutes after running.

• Use an approved fuel container.

A Safety information

• Fill the fuel tank outdoors with extreme
care.

Never remove the fuel cap in-

doors.

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,
soap and water, and change your
clothes.

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
tiously when you ride off of established
trails.

Hitting a rock or stump, or running
into wires could cause an accident and
injury.

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
ners,

drive track, slide runners, and drive

sprockets.

5. Always ride with other snowmobilers

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
tion 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

on page 79 if the snowmobile is to be
stored for an extended period.

5. Maintain or replace safety and instruction
labels, as necessary.

Engine overheating prevention

system

This model is equipped with a system, which
prevents overheating when the engine is
idling.
When the engine has been idling for 3

min­utes or longer and the coolant temperature
has risen above 100 °C (212 °F), the engine
automatically stops to prevent overheating.

NOTE:

The engine can be started after it stops.

Throttle override system

EWS00040

that the cause of the malfunction has
been corrected and that the engine can
be operated without a problem before
restarting the engine.

Control functions

• Be sure to use the specified spark plug

and spark plug cap. Otherwise, the
T.O.R.S. will not work properly.

If the throttle bodies or throttle cable malfunc­tions during operation, the T.O.R.S. will oper­ate when the throttle lever is released.
The T.O.R.S. is designed to override the fuel
injection and limit the engine speed to less
than the clutch engagement speed if the throt­tle valves fail to return to the idle position
when the throttle lever is released. (See page
81 for the clutch engagement speed.)

(See page 1.)

• Do not fill the fuel tank above the bottom

of the filler tube. Fuel could overflow if
the snowmobile is tilted or if the ambient
temperature rises, causing the fuel to
warm up and expand.

• Make sure that the fuel tank cap is
