Break-in Period
The break-in period for your new Polaris 4-cycle ATV is defined as the first ten hours of
operation, or the time it takes to use the first two full tanks of gasoline. No single action on
your part is as important as following the procedures for a proper break-in. Careful treatment
of a new engine will result in more efficient performance and longer life for the engine. Per-
form the following procedures carefully.
CAUTION
Excessive heat build-up during the first three hours of operation will damage close-fitted engine
parts. Do not operate at full throttle or high speeds for extended periods during the first three hours
of use.
Mixing brands or using a non-recommended oil may cause serious engine damage. Always use the
recommended oil. Never substitute or mix oil brands.
