1. Use the brakes wisely. Each time the brakes are
applied in all hydraulic brake systems (including
automotive applications), heat is transferred to the
brake fluid. The amount of heat transferred during
high speed stops and/or repetitive use may be high
enough to boil the brake fluid and cause the brakes
to either fade or may cause an unexpected loss of
brakes. If this occurs, the brake fluid requires a
cool down period before the brakes will again
function properly. This cool down period will vary
depending upon the ambient air temperature and
the temperature of the brake fluid. If loss of brakes
has occurred because of high fluid temperatures,
do not operate the snowmobile until the cool down
period has expired and brake lever firmness has
returned.
! WARNING
Excessive repetitive use of the hydraulic brake for
high speed stops will cause overheating of the brake
fluid and premature brake pad wear which will result
in an unexpected loss of brakes.
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 repetitive 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.
! WARNING
Use only Arctic Cat approved brake fluid. Never sub-
stitute 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.
3. Never ride the brake. Even maintaining 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 min-
utes. NEVER OPERATE THE SNOWMOBILE
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 com-
pressed position and maintains pressure against the
brake disc; however, after a period of time, the pres-
sure applied to the brake disc may relax below the
amount required to hold the snowmobile stationary.
5. Pumping the brake lever is permissible but not
acceptable on a snowmobile designed for racing;
therefore, if pumping the brake lever more than
twice is necessary to obtain the necessary stopping
power, the system must be serviced. If the operator
does not feel qualified to service the brake system,
see an authorized Arctic Cat Snowmobile dealer
for this service.
6. When new brake pads are installed, a "burnishing"
process is required. Drive the snowmobile slowly
and compress the brake lever several times until
the pads just start to heat up; then allow them to
thoroughly cool down. This process stabilizes the
pad material and extends the life of the pads.
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.
ITEM
Emergency Stop Switch
interrupts ignition circuit
Tether Switch
interrupts ignition circuit
Brake
slows the driveshaft
! WARNING
If any malfunction of the throttle system occurs (such
as freezing in fluffy snow) and the engine does not idle
down, use the emergency stop switch or disconnect
the tether switch IMMEDIATELY to stop the engine. DO
NOT start the engine until the malfunction in the car-
buretor/ throttle system has been located and cor-
rected.
! WARNING
If the throttle control lever does not work properly, DO
NOT ATTEMPT TO START THE ENGINE.
Lubrication
CHAIN CASE
The recommended amount of transmission lube in the
chain case is 236 ml (8 fl oz). Adding more transmis-
sion lube to the chain case (above the recommended
amount) may result in leakage. To check the transmis-
sion lube level, use the following procedure:
1. With the snowmobile level, shut engine off and
wait for all moving parts to stop; then open the
hood.
2. Remove the oil level stick from the chain case.
Wipe the oil level stick clean; then install the oil
level stick completely back into the chain case.
Remove the oil level stick again and check the
lubricant level.
