Battery
This snowmobile is equipped with a sealed-type (MF)
battery, which does not require any maintenance. There
is no need to check the electrolyte or to add distilled
water.
To charge the battery
Have a Yamaha dealer charge the battery as soon as
possible if it seems to have discharged. Keep in mind
that the battery tends to discharge more quickly if the
snowmobile is equipped with electrical accessories.
WARNING@ 
Battery electrolyte is poisonous and dangerous. It
contains sulfuric acid and can cause severe burns.
Avoid contact with skin, eyes, or clothing. 
ANTIDOTE: 

EXTERNAL: Flush with water. 

INTERNAL: Drink large quantities of water or
milk. Follow with milk of magnesia, beaten egg,
or vegetable oil. Call physician immediately. 

EYES: Flush with water for 15 minutes and get
prompt medical attention. 
Batteries produce explosive gases. Keep sparks,
flame, cigarettes, etc. away. Ventilate when charging
or using in an enclosed space. Always shield your
eyes when working near batteries. 
KEEP OUT OF THE REACH OF CHILDREN.

wet ... Remove carbon or wipe the
spark plugs dry; replace if necessary. 

Faulty ignition system ... Ask a Yamaha
dealer to inspect. 

T.O.R.S. system malfunction ... Discon-
nect the carburetor switch connectors
and connect the wire harness connec-
tors together to bypass the T.O.R.S.
WARNING@ 

Before bypassing the T.O.R.S., make
sure that the throttle returns prop-
erly to the fully closed position. 

The T.O.R.S. is an important safety
device; in the case of a malfunction,
take the snowmobile to a Yamaha

B. Starting the engine with a dis-
charged battery
If the snowmobile battery is discharged,
the engine can be started using a 12-volt
battery and jumper cables. Two connecting
leads have been provided for jump-starting
the snowmobile. Due to the rubber engine
mounting, the snowmobile frame is not a
suitable grounding point for jump-starting
the engine.
WARNING@ 

Connect the jumper cables only to
the connecting lead terminals. Do
not connect them to the frame or
any wire or other lead. 

When connecting the jumper cables,
do not contact the jumper cables or
connecting 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. 
@
CAUTION:@ 
Use the connecting leads to jump-start
the snowmobile only. Do not use the
connecting leads for any other purpose.
