OPERATION
VEHICLE BREAK-IN PERIOD
The break-in period for your new POLARIS vehicle is the first 25 hours of
operation, or the time it takes to use the first two tanks full of gasoline. No single
action on your part is as important as a proper break-in period. Careful treatment
of a new engine and drive components will result in more efficient performance
and longer life for these components. Perform the following procedures
carefully.
Excessive heat build-up during the first three hours of operation will damage
close-fitted engine parts and drive components. Do not operate at full throttle
or high speeds during the first three hours of use.
Use of any improper oils may cause serious engine damage. POLARIS PS-4
Full Synthetic 5W-50 4-Cycle Oil is specifically formulated for your 4-cycle
ENGINE AND DRIVETRAIN BREAK-IN
