Engine Break-In

After the completion of the break-in

period, the engine oil should be changed

and the screen should be cleaned. Other

maintenance after break-in should

include checking of all prescribed adjust-

ments 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 of operation,

always use less than ½ throttle. Varying

the engine RPM during the break-in

period allows the components to “load”

(aiding the engine/transmission compo-

nent 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.

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 com-

press brake lever to decelerate to 0-5

mph.

3. Repeat procedure twenty times.

! WARNING

Do not attempt sudden stops or put

yourself into a situation where a sud-

den stop will be required until the

brake pads are properly burnished.
