4. The brake lever lock is not a parking
brake and should not be applied for
periods exceeding
NEVER OPERATE THE SNOW-
MOBILE WITH THE BRAKE
LEVER LOCK ENGAGED.
WARNING
The brake lever lock is not a parking
brake and should not be applied for
periods exceeding 5 minutes. The
brake lever lock maintains the brake
lever in the compressed position
and maintains pressure against the
brake disc; however, after a period
of time, the pressure applied to the
brake disc may relax below the
amount required to hold the snow-
mobile stationary.
5. Pumping the brake lever is permissi-
ble; however, if pumping the brake
lever more than twice is necessary to
obtain the necessary stopping power,
immediately take the snowmobile to
an authorized Yamaha Snowmobile
dealer for service. If not under war-
ranty, this service is at the discretion
and expense of the snowmobile
owner.
6. When new brake pads are installed,
a "burnishing" process is required.

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
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 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 proce-
dure:
1. Rotate the ignition key to the OFF
position.
2. Remove ice and snow from the
throttle system and wait 5-10 minu-
tes 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.
