sure that the throttle returns properly to
the fully closed position.
●
The T.O.R.S. is an important safety de-
vice; in the case of a malfunction, take
the snowmobile to a Yamaha dealer im-
mediately for repair.

• Loose cylinder head nuts: Tighten nuts
properly.
• Worn or damaged gasket: Replace gas-
ket.
• Worn or damaged piston and cylinder:
Ask a Yamaha dealer to inspect.
Discharged battery
If the battery is discharged, the engine can be
started using a fully-charged 12-volt battery
and jumper cables. Two connecting leads
have been provided for jump-starting the
snowmobile. Due to the rubber engine mount-
ing, the snowmobile frame is not a suitable
grounding point for jump-starting the engine.
WARNING
EWS00570
●
Connect the jumper cables only to the
connecting lead terminals. Do not con-
nect them to the frame or any wire or
other lead.
●
When connecting the jumper cables, do
not contact the jumper cables or con-
necting lead terminals to each other or
to the frame or any metal part of the
snowmobile. This can cause electrical
system damage or A FIRE HAZARD.
●
Be sure to pull the lead covers back over
the terminals completely. If the termi-
nals are exposed, they could come into
contact with the frame or a metal part of
the snowmobile and this can cause elec-
trical system damage or A FIRE HAZ-
ARD.
CAUTION:
ECS00650
Use the connecting leads to jump-start the
snowmobile only. Do not use the connect-
ing leads for any other purpose.
