Throttle/Ignition Monitor Switch; Varying Altitude Operation - Arctic Cat ZR 3000 Operator's Manual

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 throttle system result-
ing in a loss of return spring force, the
monitor switch will stop the engine when
the throttle control lever is released.
! WARNING
If any malfunction of the throttle sys-
tem occurs (such as freezing in fluffy
snow) and the monitor switch does
not shut off the engine, press down
on the emergency stop switch IMME-
DIATELY to stop the engine. DO NOT
start the engine until the malfunction
in the throttle system has been
located and corrected.
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 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 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 throttle
lever slightly
