Emergency Stopping - Arctic Cat ZR 6000 R CROSS COUNTRY Operator's Manual

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 tempera-
ture 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 sys-
tem 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 substi-
tute 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 accept-
able on a snowmobile designed for racing; therefore,
if pumping the brake lever more than twice is neces-
sary to obtain the necessary stopping power, the sys-
tem must be serviced. If the operator does not feel
qualified to service the brake system, see an autho-
rized 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 throt-
tle system has been located and corrected.
! WARNING
If the throttle control lever does not work properly, DO
NOT ATTEMPT TO START THE ENGINE.
