Break-In Procedure
The Arctic Cat engine requires a short break-in period
(approximately 10 operating hours) before being sub-
jected to heavy load conditions or full-throttle operation.
Strict adherence to the break-in procedure will contribute
to optimum performance and longevity of the engine.
During break-in, a maximum of 1/2 throttle is recom-
mended; however, brief full-throttle accelerations and
variations in driving speeds contribute to good engine
break-in. After the 10 hour break-in period, the snowmo-
bile may be taken to an authorized Arctic Cat Snowmo-
bile dealer for a checkup and oil change at the discretion
and expense of the snowmobile owner.
Genuine Parts
When replacement of parts is necessary, use only genuine
Arctic Cat parts. They are precision-made to ensure high
quality and correct fit.
Drive Chain Lubrication
The drive chain should be lubricated every 20 operating
hours with a dry, graphite-based chain lubricant. By
using a dry, graphite-based chain lubricant, dirt buildup
on the drive chain will be minimized. Before each lubri-
cation, inspect the drive chain for dirt accumulation.
To lubricate the drive chain, shut the engine off and wait
for all moving parts to stop, remove the drive chain
guard, and lubricate the drive chain. After lubricating the
drive chain, install the drive chain guard.
If the drive chain is excessively dirty, it should be
removed and cleaned prior to being lubricated (see Drive
Chain and Sprockets section).
NOTE: If a dry, graphite-based chain lubricant is not
available, lubricate the drive chain with several drops of
petroleum-based oil. If the snowmobile is operated in
the summer with the optional wheel kit, the drive chain
should be lubricated more frequently.
Preparation For Storage
Prior to storing the snowmobile, it is extremely important
that it be properly serviced to prevent corrosion and com-
ponent deterioration. Arctic Cat recommends the follow-
ing procedure to prepare the snowmobile for storage.
1. Clean the seat cushion with Vinyl Protectant and a
damp cloth.
2. Clean the snowmobile thoroughly by hosing dirt,
oil, grass, and other foreign matter from the under-
carriage, tunnel, hood, and belly pan. Allow the
OILCHARTJ
snowmobile to dry thoroughly. DO NOT get water
into any part of the engine.
3. Drain all gas from the gas tank. Close the gas tank
shut-off valve by rotating it clockwise; then drain
the gasoline from the carburetor by loosening the
drain screw on the carburetor float chamber.
4. Plug the muffler outlet with a clean cloth.
5. With the ignition key in the OFF position:
A. Disconnect the high tension wire from the spark
plug; then remove the spark plug.
B. Pour 10 ml (approximately two teaspoons) of
petroleum-based oil into the spark plug hole; then
pull the recoil starter handle slowly about five
times.
Never crank the engine over without grounding the
spark plug. Damage to the transistorized ignition may
result.
C. Install the spark plug and connect the high tension
wire.
6. Remove the drive chain and clean thoroughly in a
solvent. Install drive chain and lubricate with a
dry, graphite-based chain lubricant.
7. Change the oil; then clean the air filter.
8. Lubricate the spindles and the rear suspension
with an all-temperature grease.
9. Tighten all screws, nuts, and cap screws securely.
10. Make sure all rivets holding components together
are tight. Replace all loose rivets.
11. Clean and polish the hood, console, and chassis with
Cat Cleaner (p/n 4639-371). DO NOT USE SOL-
VENTS. THE PROPELLANT WILL DAMAGE
THE FINISH.
12. If possible, store the snowmobile indoors. Raise
the rear of the snowmobile off the floor and block
up the rear end. Cover the snowmobile with a
snowmobile cover to protect it from dirt and dust.
