Polaris 2015 Ranger Diesel / Crew Diesel - Manual (Page 37)

OPERATION
Failure to operate the vehicle properly can result in a collision, loss of control, accident or rollover,
which may result in serious injury or death. Read and understand all warnings outlined in the safety
section of this manual.
Break-In Period
The break-in period for your new RANGER is the first 50 hours of operation. 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.
NOTICE: 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.
Engine and Drivetrain Break-in
1. Fill the fuel tank with clean, fresh fuel.
2. Check the oil level. 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 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 36.
6. During the break-in period, change both the oil and the filter at 50 hours.
7. Check fluid levels of transmission and all gearcases after the first 25 hours of operation
and every 100 hours thereafter.
8. Pull only light loads.
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 any debris from the clutch air duct and from the engine
compartment. See page 77.
