Recommended Oil

NOTE: This snowmobile comes
from the factory with SAE 5W-30
multi-grade oil installed.
The recommended oil to use in the
engine is a multi-grade oil calibrated to
the ambient temperature at which the
engine is run. See the viscosity chart
for details.
GEN-0048
ENGINE BREAK-IN
The engine requires a short break-in
period (approximately 10 operating
hours) before being subjected to heavy
load conditions or full-throttle opera-
tion. 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 recommended; however,
brief full-throttle accelerations and
variations in driving speeds contribute
to good engine break-in. After the 10
hour break-in period, the snowmobile
may be taken to an authorized Arctic
Cat Snowmobile dealer for a checkup
and oil change. This service is at the
discretion and expense of the snowmo-
bile owner.
MUFFLER
The muffler is designed to reduce
engine noise and improve the total per-
formance of the engine. If the muffler
is removed from the engine, severe
engine damage will result.
! WARNING
Always fill the gas tank in a well-
ventilated area. Never add gasoline
to the gas tank near any open
flames or with the engine running.
DO NOT SMOKE while filling the
gas tank.
CAUTION
Any oil used in place of the recom-
mended oil may cause serious
engine damage.
