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.
