OPERATION
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 fuel. No single action on your part is as
important as following the procedures for a proper break-in. Careful
treatment of a new engine will result in more efficient performance and
longer life for the engine. Perform the following procedures carefully.
The first tank of fuel must be pre-mixed according to the following
instructions. After the break-in period, the oil injection system will
provide the necessary engine lubrication without pre-mixing.
1. Mix 12.8 ounces of Polaris 2-cycle oil to four gallons (or 16
ounces to five gallons) of gasoline in a suitable gas container. Fill
the fuel tank. See page 43.
2. Fill the oil tank with Polaris 2-cycle oil.
3. Drive slowly at first. Select an open area that will allow room to
familiarize yourself with vehicle operation and handling.
4. Vary the throttle positions.
5. Perform regular checks on fluid levels, controls, and areas outlined
on the daily pre-ride inspection checklist. See page 58.
After the first tank of pre-mixed fuel has been used, verify that the oil
level in the oil tank has dropped, indicating that the oil pump is
functioning properly. If the level has not dropped, see your dealer for
oil pump bleeding and repeat the pre-mix procedure.
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 for extended periods during the first three hours of
use.
Use of any oils other than those recommended by Polaris may
cause serious engine damage. We recommend the use of Polaris
2-cycle oil for your 2-cycle engine.
Lack of proper lubrication will cause serious engine damage.
Always fill the oil tank when refueling the ATV.
