Break-In Period
Engine Break-In
The break-in period for your new snowmobile is defined as the first ten
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.
1. Fill the fuel tank with gasoline.
2. Check the oil level. See page 61.
3. Drive slowly at first. Select an area that's open and will allow 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 pages 19 and 25.
6. Change the oil after the first 20 hours of operation.
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 during
the first three hours of use.
