NOTE: Do not rotate the handlebar
to a position that allows air to enter
the brake system.
Exhaust System
The exhaust system is designed to reduce
noise and to improve the total perfor-
mance of the engine. If any exhaust sys-
tem component is removed from the
engine and the engine is run, severe
engine damage will result.
Air-Intake Silencer
Used in conjunction with the fuel intake
system is a specially designed air-intake
silencer. The purpose of the silencer is to
quiet the intake of fresh air. Since the fuel
intake system is calibrated with the air-
intake silencer in place, the engine must
never be run with the silencer removed.
Performance will not be improved if the
air-intake silencer is removed. In con-
trast, severe engine damage will occur.
Cooling System
These snowmobiles are equipped with a
closed liquid cooling system for engine
cooling. The cooling system should be
inspected daily for leakage and damage.
Also, the coolant level should be checked
daily. If leakage or damage is detected,
take the snowmobile to an authorized
Arctic Cat Snowmobile dealer for ser-
vice. If not under warranty, this service is
at the discretion and expense of the
snowmobile owner.
When filling the cooling system, use an
ethylene glycol-based coolant/water mix-
ture which will satisfy the coldest antici-
pated weather conditions of your area in
accordance with the coolant manufac-
turer’s recommendations.
NOTE: If operating on low snow,
ice, or hard-packed snow conditions,
it is recommended that Ice Scratch-
ers (p/n 5639-897) be installed and
engaged to reduce wear strip wear
and engine overheating.
For checking/filling cooling system, refer
to the Coolant Level sub-section in the
Maintenance section.
Battery
(Electric Start)
It is extremely important that the battery
be maintained at full charge at all times
and that the battery connections be clean
and tight. If charging the battery becomes
necessary, refer to Battery sub-section in
the Maintenance section.
Jump-Starting
NOTE: Arctic Cat does not recom-
mend jump-starting a snowmobile
with a dead battery, but rather to
remove the battery, service it, and
correctly charge it; however, in an
emergency, it may be necessary to
jump-start a snowmobile. If so, use
the following procedure to carefully
and safely complete this procedure.
! WARNING
Tighten cap screws according to
specifications to prevent unexpected
“movement” of the handlebar during
operation over rough terrain. DO NOT
position the handlebar so steering
(maximum right/left turning capabili-
ties) or throttle and brake controls
are affected.
! WARNING
If at any time the battery is removed/
disconnected and a jumper pack will
be used to start the snowmobile,
always use the key or emergency
stop switch to turn the engine off.
Never disconnect the jumper pack
with the engine running. Failure to do
this will cause damage to the voltage
regulator/rectifier.
! WARNING
Improper handling or connecting of a
battery may result in severe injury
including acid burns, electrical
burns, or blindness as a result of an
explosion. Always remove rings and
watches. Any time service is per-
formed on a battery, the following
must be observed: keep sparks, open
flame, cigarettes, or any other flame
away. Always wear safety glasses.
Protect skin and clothing when han-
dling a battery. When servicing a bat-
tery in an enclosed space, keep the
area well-ventilated.
