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.
Fuel System
Gasoline Additives
Fuel de-icer can be used for all models.
Also, periodic use of an injector cleaner
is recommended especially in the last
tank of gasoline before storage. Arctic
Cat Fuel Stabilizer (p/n 0436-907) should
also be added to the last tank of gasoline
before storage.
Fuel Pickup Valves
All models are equipped with fuel pickup
valves in the gas tank. If ever there is a
restricted fuel flow and a pickup valve is
suspected, take the snowmobile to an
authorized Arctic Cat Snowmobile dealer
for this service. If not under warranty,
this service is at the discretion and
expense of the snowmobile owner.
Coolant Level
NOTE: Use a good quality, ethyl-
ene glycol-based, automotive-type
coolant.
NOTE: Always check the coolant
level with the engine cold.
Locate the appropriate FULL mark on
the coolant reservoir. If coolant is below
the FULL mark, add coolant to the FULL
mark.
Spark Plugs
NOTE: Always use the recom-
mended spark plugs in the engine.
See the appropriate specifications
chart for correct spark plug gap.
Varying terrain conditions and operating
usage may require spark plugs of a differ-
ent heat range. For example, sustained
cross-country riding will usually require
colder heat-range spark plugs while trail
riding or other continual slow speed
operation will usually require hotter heat-
range spark plugs.
Removing/Installing Spark
Plugs
1. Remove the springs securing the
expansion chamber to the exhaust
manifold and resonator.
2. Move the expansion chamber out of
the way to access the spark plugs.
3. Remove the spark plug caps from
the plugs.
4. Using a spark plug wrench, remove
the plugs.
5. Install the plugs and finger-tighten.
6. Tighten the spark plugs to 19 ft-lb;
then install the spark plug caps.
7. Place the expansion chamber into
position and secure to the exhaust
manifold and resonator with the
springs.
! WARNING
Whenever any maintenance or
inspection is made on the fuel sys-
tem in which there may be fuel leak-
age, there should be no welding,
smoking, open flames, etc., in the
area.
CAUTION
If the coolant is below the FULL
COLD mark and if coolant has been
added, immediately inspect for leak-
age and/or damage. If leakage or
damage is detected, take the snow-
mobile to an authorized Arctic Cat
Snowmobile dealer for service. If not
under warranty, this service is at the
discretion and expense of the snow-
mobile owner.
