Break-In Procedure

A new ATV and an overhauled ATV engine require a
"break-in" period. The first 10 hours (or 200 miles) are
most critical to the life of this ATV. Proper operation dur-
ing this break-in period will help assure maximum life
and performance from the ATV.
During the first 10 hours (or 200 miles) of operation,
always use less than 1/2 throttle. Varying the engine
RPM during the break-in period allows the components
to "load" (aiding the mating process) and then "unload"
(allowing components to cool). Although it is essential to
place some stress on the engine components during
break-in, care should be taken not to overload the engine
too often. Do not pull a trailer or carry heavy loads dur-
ing the 10-hour break-in period.
When the engine starts, allow it to warm up properly. Idle
the engine several minutes until the engine has reached
normal operating temperature. Do not idle the engine for
excessively long periods of time.
During the break-in period, 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 completion of the break-in period, the engine
oil and oil filter should be changed. Other maintenance
after break-in should include checking of all prescribed
adjustments and tightening of all fasteners.

Gasoline - Oil - Lubricant

RECOMMENDED GASOLINE

The recommended gasoline to use is 87 minimum octane
regular unleaded. In many areas, oxygenates (either etha-
nol or MTBE) are added to the gasoline. Oxygenated
gasolines containing up to 10% ethanol, 5% methane, or
5% MTBE are acceptable gasolines.
When using ethanol blended gasoline, it is not necessary
to add a gasoline antifreeze since ethanol will prevent the
accumulation of moisture in the fuel system.
CAUTION
Do not use white gas. Only Arctic Cat approved gaso-
line additives should be used.
RECOMMENDED ENGINE/
TRANSMISSION OIL
CAUTION
Any oil used in place of the recommended oil could
cause serious engine damage. Do not use oils which
contain graphite or molybdenum additives. These oils
can adversely affect clutch operation. Also, not recom-
mended are racing, vegetable, non-detergent, and cas-
tor-based oils.
