The longevity and safety of the snowmo-
bile can be increased by making periodic
checks of the items in the preceding
checklist.
If, at any time, abnormal noises, vibra-
tions, or improper working conditions of
any component of this snowmobile are
detected, DO NOT OPERATE THE
SNOWMOBILE. Take the snowmobile
to an authorized Arctic Cat Snowmobile
dealer for inspection and adjustment or
repair. If not under warranty, this service
is at the discretion and expense of the
snowmobile owner.
The snowmobile should be taken to an
authorized Arctic Cat Snowmobile dealer
at the end of each snowmobiling season
for general inspection and for off-season
storage servicing. This inspection and
servicing is at the expense of the snow-
mobile owner.
Air Cleaner/Filter (1100
cc Turbo Models)
The air filter inside the air cleaner housing
must be kept clean to provide good engine
power and gas mileage. If the snowmobile
is used under normal conditions, inspect
the filter weekly and replace the filter at
the intervals specified. If operated in
adverse conditions, inspect and service the
filter more frequently. Use the following
procedure to remove the filter and to
inspect and/or replace it.
CAUTION
Failure to inspect the air filter fre-
quently if the snowmobile is used in
adverse conditions can damage the
turbocharger/engine.

NOTE: For this procedure, the
hood must be removed (see Access
Panel/Hood (Removing/Installing) in
the General Information section of
this manual).
1. Remove the air filter from the housing.
2. Inspect the air filter for dirt or damage.
CAUTION
Do not use compressed air in an
attempt to clean the filter. Damage to
the filter may occur. If the filter is
dirty, it must be replaced.

CAUTION
A torn air filter can cause damage to
the turbocharger/engine.
nants may get inside the turbo-
charger/engine if the filter is torn.
Carefully examine the filter for holes
or tears. Replace the filter with a new

3. Clean any debris from inside the air
intake plenum.
4. Place the new filter (if necessary)
into the housing.
5. Install the hood (see Access Panel/Hood
(Removing/Installing) in the General
Information section of this manual).

turbocharger/engine will occur.

Fuel System

! WARNING
Whenever any maintenance or inspec-
tion is made on the fuel system in
which there may be fuel leakage, there
should be no welding, smoking, open
flames, etc., in the area.
In-Line Fuel Filter (1100 cc
Models)
Arctic Cat recommends that the in-line fuel
filter be replaced every 5000 miles. The fil-
ter must be clean to allow the fuel hose to
transmit the amount of gasoline required.
If the in-line fuel filter is obstructed, gas-
oline flow will be restricted; therefore,
the filter must be replaced. To remove
and install the in-line fuel filter, use the
following procedure:
! WARNING
Since the fuel supply hose may be
under pressure, always wear safety
glasses; then remove the hose slowly
to release the pressure. Place an
absorbent towel around the connec-
tion to absorb the fuel.

NOTE: Before removing the fuel fil-
ter, take note that the filter is direc-
tional and the arrow should be
directed towards the engine.
