Operation; Break-In Period - Polaris Sportsman 850SP Owner's Manual

WARNING
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 20 hours of
operation. 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.
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 31. Always exercise
extreme caution whenever handling gasoline.
2. Check the engine oil level on the dipstick. See page 83. 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 48.
6. Pull only light loads.
7. Change both the oil and the filter at 25 hours.
8. Check fluid levels of transmission and all gearcases after the first 25
hours of operation and every 100 hours thereafter.
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.
If a belt fails, always clean away all debris when replacing the belt.
