THROTTLE/IGNITION
MONITOR SWITCH
The throttle control is equipped with a
monitor switch for safety purposes
which will stop the engine when a loss
of return spring force occurs. If ice
forms in the throttle system or if there
is some other malfunction of the throt-
tle system resulting in a loss of return
spring force, the monitor switch will
stop the engine when the throttle con-
trol lever is released.
! 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 emergency stop
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
abruptly when the throttle control lever
is released and the activation of the
monitor switch is suspected, use the
following procedure:
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 sev-
eral 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
engine. If the engine now starts
and stops when the throttle lever is
released, take the snowmobile to
an authorized Arctic Cat Snowmo-
bile dealer for service. If not under
warranty, this service is at the dis-
cretion and expense of the snow-
.

dures.
