VEHICLE BREAK-IN PERIOD
2-Cycle Engines
The break in period for your new Polaris ATV is defined as the time
it takes to use the first tank 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. Perform the following procedures carefully.
1. Mix 12.8 ounces of injection oil to four gallons (or 16 ounces to
5 gallons) of gasoline in a suitable gas can. Fill the fuel tank as
outlined on page 58.
2. Fill the oil tank with Polaris injection oil.
3. Drive slowly at first. Select an area which is open and will give
you room to familiarize yourself with vehicle operation and han-
dling.
4. Vary the throttle positions.
5. Perform regular checks on fluid levels, controls and all impor-
tant areas on the vehicle as outlined earlier on the daily pre-ride
inspection checklist found on page 12.
Use only Polaris injection oil. Never substitute or mix oil
brands. Serious engine damage and voiding of warranty can
result.
Do not operate at full throttle or high speeds for extended
periods during the first three hours of use. Excessive heat
can build up and cause damage to close fitted engine
parts.
