OPERATION
Vehicle Break-In Period
The break-in period for your new Polaris RANGER is the first twenty
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 will result in more
efficient performance and longer life for the engine. Perform 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.
Use of any oils other than those recommended by Polaris may
cause serious engine damage. We recommend the use of
Polaris Premium 4 Synthetic Oil for your 4-cycle engine.
1. Fill the fuel tank with gasoline. Heed the gasoline warnings on
page 22.
2. Check the oil level on the dipstick. See page 61. Add Polaris
Premium 4 Synthetic Oil if necessary to maintain the oil level in
the normal (safe) operating range.
3. Drive slowly at first. Select an open area that allows room to
familiarize yourself with vehicle operation and handling.
4. Vary throttle positions. Do not operate at sustained idle.
5. Perform regular checks on fluid levels, controls and areas outlined
on the daily pre-ride inspection checklist. See page 33.
6. Pull only light loads.
7. During the break-in period, change both the oil and the filter at 25
hours.
