4. Plug the exhaust system outlet with a clean cloth.
5. Fill the gas tank to its rated capacity; then add
Arctic Cat Fuel Stabilizer (p/n 0638-165) to the
gas tank following directions on the container for
the stabilizer/gasoline ratio. Tighten the gas tank
cap securely.
6. Drain the chain-case lubricant by removing the
chain-case drain plug located on the backside of
the chain-case assembly. Remove the chain-case
cover and inspect chain, sprockets, chain
tensioner, and rollers for wear and the chain for
proper tension. Install the drain plug, chain-case
cover, and seal; then pour Arctic Cat Transmission
Lube (p/n 0636-817) into the filler hole according
to appropriate specifications.
7. Remove the drive belt from the drive clutch/driven
pulley. Lay the belt on a flat surface or slide it into
a cardboard sleeve to prevent warping or distortion
during storage; then clean and inspect the drive
clutch and driven pulley.

suspension, spindles, speedometer drive adapter,
and the driven shaft support bearing) with a low-
temperature grease.

PELLENT WILL DAMAGE THE FINISH.

disconnect the negative cable first; then clean the
battery posts and cables.
13. If possible, store the snowmobile indoors. Raise
the track off the floor by blocking up the back end
making sure the snowmobile is secure. Loosen the
track adjusting bolts to reduce track tension. Cover
the snowmobile with a machine cover or a heavy
tarpaulin to protect it from dirt and dust.
14. If the snowmobile must be stored outdoors,
position the snowmobile out of direct sunlight;
then block the entire snowmobile off the ground
making sure the snowmobile is secure. Loosen the
track adjusting bolts to reduce track tension. Cover
with a machine cover or a heavy tarpaulin to
protect it from dirt, dust, and rain.
Preparation After
Storage
Taking the snowmobile out of storage and correctly pre-
paring it for another season will assure many miles and
hours of trouble-free snowmobiling. Arctic Cat recom-
mends the following procedure:
1. Clean the snowmobile thoroughly. Polish the
exterior of the snowmobile.
2. Clean the engine. Remove the cloth from the
exhaust system. Check exhaust system and air-
intake silencer/air filter for obstructions.
3. Inspect all control wires and cables for signs of
wear or fraying. Replace if necessary. Use cable
ties or tape to route wires and cables away from
hot or rotating parts.
4. Remove and inspect the drive belt for cracks and
tears. Check belt specifications. Replace if
damaged or worn. Install the drive belt.

Installing Drive Belt in Section 8 of this manual.
„
NOTE: If the old belt is worn but in reasonable
condition, retain it with the snowmobile as a spare
in case of emergency.
5. Inspect all fuel hoses and oil hoses for
deterioration or cracks; replace if necessary. Make
sure all connections are tight.
6. Inspect the entire brake system, all controls,
headlight, taillight, brakelight, ski wear bars, and
headlight aim; adjust or replace as necessary.
7. Inspect each spark plug. Replace, gap, or clean as
necessary.
8. Adjust the track to the proper tension and
alignment. Lock the jam nuts.
! CAUTION
Avoid storing in direct sunlight and using a
plastic cover as moisture may collect on the
snowmobile causing corrosion.
