Recommended Gasoline
and Oil
RECOMMENDED GASOLINE
The recommended gasoline to use in these snowmobiles
is 87 octane regular unleaded.

NOTE: In many areas, oxygenates are added to the
gasoline. Oxygenated gasolines containing up to 10%
ethanol are acceptable gasolines; however, whenever
using oxygenated gasolines, the carburetor main jet
must be one size larger than the main jet required for
regular unleaded gasoline. For example, if a 77.5 main
jet is recommended for regular unleaded gasoline, a
78.5 main jet must be installed if using an oxygenated
gasoline.
When using ethanol blended gasoline, adding a gasoline
antifreeze is not necessary since ethanol will prevent the
accumulation of moisture in the fuel system.
RECOMMENDED OIL
The recommended oil to use in the engine is 0W-40 Syn-
thetic oil. See the viscosity chart for details.

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 undercar-
riage, tunnel, hood, and belly pan. Allow the snow-
mobile 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.
CAUTION
Do not use white gas or gasolines containing methanol.
Only Arctic Cat approved gasoline additives should be
used.
CAUTION
Any oil used in place of the recommended oil may
cause serious engine damage.
