OPERATION
Failure to operate the ATV properly can result in a collision, loss of control,
accident or overturn, which may result in serious injury or death. Read and
understand all safety warnings outlined in the safety section of this owner’s
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.
NOTICE: 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.
Engine and Drivetrain Break-in
1. Fill the fuel tank with gasoline. See page 33. Always exercise
extreme caution whenever handling gasoline.
2. Check the engine oil level on the dipstick. See page 73. Add oil if
necessary to maintain the level between the safe and add marks.
3. Drive slowly at first. Select an open area that allows room to famil-
iarize yourself with vehicle operation and handling.
4. Vary the 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 50.
6. Pull only light loads.
7. Change both the oil and the filter at 20 hours, one month or 500
miles (800 km), whichever comes first.
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.
