Break-In Procedure
A new vehicle and an overhauled engine require a
“break-in” period. The first 10 hours (or 200 miles) are
most critical to the life of this vehicle. Proper operation
during this break-in period will help assure maximum life
and performance from the vehicle.
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 (see Periodic
Maintenance Chart in Section 2).
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.
RECOMMENDED ENGINE/
TRANSMISSION OIL
The recommended oil to use is Arctic Cat ACX All
Weather synthetic engine oil, which has been specifi-
cally formulated for use in this Arctic Cat engine.
Although Arctic Cat ACX All Weather synthetic engine
oil is the only oil recommended for use in this engine,
use of any API certified SM 5W-50 oil is acceptable.
OILCHARTI
RECOMMENDED FRONT
DIFFERENTIAL/REAR DRIVE
LUBRICANT
The recommended lubricant is Arctic Cat Gear Lube or
an equivalent gear lube which is SAE approved 80W-90
hypoid. This lubricant meets all of the lubrication
requirements of the Arctic Cat vehicle front differential
and rear drive.
CAUTION
Do not use white gas. Only Arctic Cat approved gas-
oline additives should be used.
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
recommended are racing, vegetable, non-detergent,
and castor-based oils.
CAUTION
Any lubricant used in place of the recommended
lubricant could cause serious front differential/rear
drive damage.
