Recommended Front
Differential/Rear Drive
Lubricant
NOTE: Arctic Cat recommends
the use of genuine Arctic Cat lubri-
cants.The recommended lubricant
(front differential and rear drive) is
SAE approved 80W-90 hypoid. This
lubricant meets all of the lubrication
requirements of the Arctic Cat ATV.
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. At the discretion and
expense of the owner/operator, the ATV
may be taken to an authorized Arctic Cat
ATV dealer for this initial service.
New ATV’s and renewed ATV engines
require a “break-in” period. The first
month is most critical to the life of this
ATV. Proper operation during this break-
in period will help assure maximum life
and performance from the ATV.
During the first 10 hours or 100 miles of
operation, always use less than ½ throt-
tle. Varying the engine RPM during the
break-in period allows the components to
“load” (aiding the engine/transmission
component 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 during the break-in period.
When the engine starts, allow it to warm
up properly. Idle the engine several min-
utes until the engine has reached normal
operating temperature. Do not idle the
engine for excessively long periods of
time.
Burnishing Brake Pads
Brake pads must be burnished to achieve
full braking effectiveness. Braking dis-
tance will be extended until brake pads
are properly burnished.
To properly burnish the brakes, use fol-
lowing procedure:
1. Choose an area sufficiently large to
safely accelerate ATV to 30 mph and
to brake to a stop.
2. Accelerate to 30 mph; then release
the throttle lever and compress brake
lever to decelerate to 0-5 mph.
3. Repeat procedure twenty times.
CAUTION
Any lubricant used in place of the
recommended lubricant could cause
serious front differential/rear drive
damage.
! WARNING
Do not attempt sudden stops or put
yourself into a situation where a
sudden stop will be required until
the brake pads are properly bur-
nished.
