NOTE: If operating on ice or hard-
packed snow conditions, it is recom-
mended that Ice Scratchers be used
to reduce wear strip wear and engine
overheating.
For checking/filling cooling system, refer
to the Coolant Level sub-section in the
Maintenance section.
Battery
(Electric Start)
It is extremely important that the battery
be maintained at full charge at all times
and that the battery connections be clean
and tight. If charging the battery becomes
necessary, refer to Battery sub-section in
the Maintenance section.
Jump-Starting
NOTE: Yamaha does not recom-
mend jump-starting a snowmobile
with a dead battery, but rather to
remove the battery, service it, and
correctly charge it; however, in an
emergency, it may be necessary to
jump-start a snowmobile. If so, use
the following procedure to carefully
and safely complete this procedure.
1. On the snowmobile to be jump-started,
slide any terminal boots away.
2. Inspect the battery for any signs of
electrolyte leaks, loose terminals, or
bulging sides. Leaking or bulging
battery cases may indicate a frozen
or shorted battery.
3. Inspect the vehicle to be used for
jump-starting to determine if voltage
and ground polarity are compatible.
The vehicle must have a 12-volt DC,
negative ground electrical system.
4. Move the vehicle to be used for the
jump-start close enough to ensure
the jumper cables easily reach; then
set and lock the brakes, shut off all
electrical accessories, and turn the
ignition switch OFF.
NOTE: Make sure all switches on
the snowmobile to be jump-started
are turned OFF.
5. Disconnect all external accessories
such as cell phones, GPS units, and
radios on both vehicles.
6. Attach one clamp of the positive
(red) cable to the positive (+) termi-
nal (1) of the dead battery (C) being
careful not to touch any metal with
the other clamp; then attach the
other clamp of the positive (red)
cable to the positive (+) terminal (2)
of the good battery (B).
! WARNING
If at any time the battery is removed/
disconnected and a jumper pack will
be used to start the snowmobile,
always use the key or engine stop
switch to turn the engine off. Never
disconnect the jumper pack with the
engine running. Failure to do this will
cause damage to the voltage regula-
tor/rectifier.
! WARNING
Improper handling or connecting of a
battery may result in severe injury
including acid burns, electrical
burns, or blindness as a result of an
explosion. Always remove rings and
watches. Any time service is per-
formed on a battery, the following
must be observed: keep sparks, open
flame, cigarettes, or any other flame
away. Always wear safety glasses.
Protect skin and clothing when han-
dling a battery. When servicing a bat-
tery in an enclosed space, keep the
area well-ventilated.
! WARNING
If any of these conditions exist, DO
NOT attempt to jump-start, boost, or
charge the battery. An explosion
could occur causing serious injury.
CAUTION
Always make sure the electrical sys-
tems are of the same voltage and
ground polarity prior to connecting
jumper cables. If not, severe electri-
cal damage may occur.
CAUTION
Failure to disconnect electronic
accessories during jump-starting
may cause system damage due to
power spikes.
