Break-In Period; Engine And Drivetrain Break-In - Polaris Sportsman 450 Owner's Manual

OPERATION

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
procedures 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.
CAUTION
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 37.
2. Check the oil reservoir level on the dipstick. See page 70. 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
familiarize 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 47.
6. Pull only light loads.
7. During the break-in period, change both the oil and the filter at 20
hours, 200 miles, or one month, 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 during the break-in period.
