2. Be sure to maintain the brake fluid at
the proper level and take care not to
get any moisture in the system as
moisture in the brake fluid lowers the
boiling point. If the brake fluid is ever
boiled (by high speed stops or repeti-
tive use) or if moisture is allowed to
enter the system, it must be changed.
Never substitute or mix different types
or grades of brake fluid.
3. Never ride the brake. Even main-
taining minimal pressure on the
brake lever will cause the brake pads
to drag on the disc and may overheat
the brake fluid.
4. The brake lever lock is not a parking
brake and should not be applied for
periods exceeding 5 minutes.
NEVER OPERATE THE SNOW-
MOBILE WITH THE BRAKE
LEVER LOCK ENGAGED.
5. Pumping the brake lever is permissible;
however, if pumping the brake lever
more than twice is necessary to obtain
the necessary stopping power, immedi-
ately take the snowmobile to an autho-
rized Arctic Cat Snowmobile dealer for
service. If not under warranty, this ser-
vice is at the discretion and expense of
the snowmobile owner.
6. When new brake pads are installed,
a “burnishing” process is required.
Emergency Stopping
There are several methods of stopping or
slowing the snowmobile under a variety
of situations. Identified in the following
chart are the ways a snowmobile may be
brought to a stop and the effectiveness
under normal conditions.
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.
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.
! WARNING
Use only Arctic Cat approved DOT 4
brake fluid. Never substitute or mix
different types or grades of brake
fluid. Brake loss can result. Check
brake fluid level and pad wear before
each use. Brake loss can result in
severe injury or even death.
! 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 snowmobile stationary.

! WARNING
If any malfunction of the throttle sys-

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.
