Emergency Stopping; Lubrication; Chain Case; Front Suspension - Arctic Cat 2014 SNO PRO 500 Operator's Manual

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.

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 synthetic chain lube in
the chain case is 236 ml (8 fl oz). Adding more lube to
the chain case (above the recommended amount) may
result in leakage. To check the lube level, use the fol-
lowing 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.
3. If the lubricant level is above the add mark, the
lubricant level is satisfactory. If the lubricant level
is at or below the add mark, proceed to step 4.
4. If oil is low, add synthetic chain lube through the oil
level stick filler hole. When the oil level is correct,
install the oil level stick.
NOTE: If excessive oil deposits are noticed, the
chain case must be serviced. Also, when the oil
level is at the add mark, approximately 60 ml (2 fl
oz) of lube must be added to the chain case.
CAUTION
The correct lubricant to use in the chain case is Arctic
Cat Synthetic Chain Lube (p/n 5639-038). Any substi-
tute may cause premature chain failure or serious
damage to the chain drive system.

FRONT SUSPENSION

It is very important that the bellcrank is greased on a
monthly basis using a good all-temperature grease.
The bellcrank should also be greased after trailering
the snowmobile on an open trailer. Pump grease into
the grease fittings and wipe excess grease from the
bellcrank.
