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 (5000)
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.
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 (5000)
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.
1. On the snowmobile to be jump-started,
slide any terminal boots away.
2. Inspect the battery for any signs of
electrolyte leaks, loose terminals, or
bulging sides. Leaking or bulging
battery cases may indicate a frozen
or shorted battery.
3. Inspect the vehicle to be used for
jump-starting to determine if voltage
and ground polarity are compatible.
The vehicle must have a 12-volt DC,
negative ground electrical system.
CAUTION
These snowmobiles are not designed
to be operated in dusty conditions.
Operating the snowmobile in dusty
conditions
will
result
in
severe
engine damage.
CAUTION
On the 5000, always turn the ignition
switch key to the OFF position when
the snowmobile is not being used.
Leaving the ignition switch in the ON
position will result in discharging the
battery and possible damage to the
battery.
! 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.
! WARNING
Any time service is performed on a bat-
tery, the following must be observed:
keep sparks, open flame, cigarettes, or
any other flame away. Always wear
safety glasses. Protect skin and cloth-
ing when handling a battery. When ser-
vicing a battery in an enclosed space,
keep the area well-ventilated.
! WARNING
If any of these conditions exist, DO
NOT attempt to jump-start, boost, or
charge the battery. An explosion
could occur causing serious injury.
CAUTION
Always make sure the electrical sys-
tems are of the same voltage and
ground polarity prior to connecting
jumper cables. If not, severe electrical
damage may occur.
