OPERATION
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 pro-
cedures carefully.
Engine and Drivetrain Break-in
1. Fill the fuel tank with gasoline. Heed the gasoline warnings on page
21.
2. Check the oil level. See page 68. Add the recommended oil as
needed to maintain the oil level in the normal (safe) operating
range.
3. Drive slowly at first. Select an open area that allows room to famil-
iarize 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 41.
6. Pull only light loads.
7. During the break-in period, change both the oil and the filter at 25
hours.
8. Inspect and adjust park brake cable tension after the first 25 hours of
operation and every 100 hours thereafter to ensure proper cable ten-
sion. See page 88.
PVT Break-in (Clutches/Belt)
A proper break-in of the clutches and drive belt will ensure a longer life
and better performance. Break in the clutches and belt by operating at
slower speeds during the break-in period as recommended. Pull only
light loads. Avoid aggressive acceleration and high speed operation dur-
ing the break-in period.
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.
