WARNING
If any malfunction of the throttle
system occurs (such as freezing in
fluffy snow) and the monitor switch
does not shut off the engine, press
down
on
the
switch IMMEDIATELY to stop the
engine. DO NOT start the engine
until the malfunction in the throttle
system has been located and cor-
rected.
If the snowmobile engine stops abruptly
when the throttle control lever is released
and the activation of the monitor switch
is suspected, use the following proce-
dure:
1. Rotate the ignition key to the OFF
position.
2. Remove ice and snow from the
throttle system and wait 5-10 min-
utes for the engine heat to thaw ice
from the throttle system.
3. Test the throttle control lever by
compressing and releasing it several
times. The lever MUST return to the
idle position quickly and completely.
NOTE: If the throttle control lever
operates properly and the engine
does not start, compress the throt-
tle lever slightly (approximately 1/8
throttle) and try starting the engine.
If the engine now starts and stops
when the throttle lever is released,
take the snowmobile to an autho-
rized Yamaha Snowmobile dealer
for service. If not under warranty,
this service is at the discretion and
expense of the snowmobile owner.
WARNING
If the throttle control lever does not
work properly, DO NOT ATTEMPT
TO START THE ENGINE.
4. If the throttle control lever operates
properly, rotate the ignition key to
the RUN position and go through
normal starting procedures.
