Polaris 300 2X4 Offroad Vehicle User Manual

Break-In Period
The break-in period for your new Polaris ATV is 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 proce-
dures for a proper break-in. Careful treatment of a new engine and drive
components will result in more efficient performance and longer life for
these components.
Install the accessory oil cooler when the following conditions exist:
The vehicle will be used for towing heavy loads.
The vehicle will be used for dragging ground surfaces or performing
similar activities.
The vehicle is normally operated when the air temperature is above
100° F. (38° C).
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.
