OPERATION
Break-In Period
Engine Break-In
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. Vary the
throttle openings and vehicle speeds to reduce friction on all close-
fitting machined parts, allowing them to break in slowly without
damage.
NOTICE: Use of any lubricants other than those recommended by POLARIS
may cause serious engine damage. We recommend the use of
POLARIS lubricants for your vehicle.
Drive with extra caution during the break-in period. Perform regular
checks on fluid levels, lines and all other important areas of the
snowmobile.
Oil Injection System
Always check and fill the oil tank when refueling. See page 51.
NOTICE: Serious engine damage can occur without the proper lubrication.
Check the oil tank level often during the first tank of fuel. If the oil level
doesn't go down, contact your dealer immediately.
Drive Belt Break-In
The break-in period for a new drive belt is 30 miles (48 km). During this
time, vary the throttle position under 50% and limit full throttle use.
New drive belts that feature a sanded finish should be first washed with
warm, soapy water and allowed to air dry prior to use.
Always take time to warm up the belt and driveline prior to operating
the snowmobile. Free the track and skis from the ground before
engaging throttle.
