Operating Instructions
Starting and Stopping
Engine
It is imperative that all safety checks
found in the accompanying Snowmobile
Safety Handbook be performed before
attempting to start the engine.
This snowmobile is equipped with a
recoil starter. The recoil starter handle is
located on the lower right-hand side of
the console.
NOTE: If the recoil starter rope
should break or if the recoil starter
should malfunction, take the snow-
mobile to an authorized Yamaha
Snowmobile dealer for service.
To start the engine, use the following pro-
cedure:
0749-930
1. Test the throttle lever by completely
compressing and releasing it several
times. The lever MUST return to the
idle position quickly and completely.
2. Open the gas tank shut-off valve
located under the gas tank by rotating
the valve counterclockwise. Open the
valve completely; otherwise, it may
close during operation of the snow-
mobile due to engine vibration.
0744-944
3. Insert the key into the ignition
switch; then rotate the key to the
RUN position.
NOTE: Make sure the emergency
stop switch is in the ON (up) position
and the tether cap is connected to
the tether switch.
4. For a cold engine, pull the choke out
completely. If the engine is warm,
choking is not normally necessary.
5. Pull the recoil starter handle slowly
until resistance is felt; then give a
short quick pull. The engine should
start; however, if the engine does not
start, repeat this step.
6. When the engine starts, push the
choke approximately half way in.
Allow a cold engine to “warm up”
for approximately 2-3 minutes. The
choke should be pushed in com-
pletely after the “warm up.”
7. Flooding - If the engine does not
start when the choke is being used
but seems ready to start, push the
choke in completely.
NOTE: Continued choking will only
cause the engine to flood more.
NOTE: If the engine fails to start
during the attempt with the throttle
lever compressed, remove the spark
plug and clean and dry it thoroughly
or install a new, properly gapped,
recommended spark plug.
! WARNING
Never allow anyone to stand in front
of the snowmobile at any time, espe-
cially when starting the engine.
CAUTION
To avoid damaging the recoil starter,
DO NOT pull the recoil starter rope to
its limit or release the recoil starter
handle from an extended position.
Allow recoil rope to rewind slowly.
