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-fit-
ting 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 snow-
mobile.
Oil Injection System
Always check and fill the oil bottle when refueling. See page 69.
NOTICE:
Serious engine damage can occur without the proper lubrication.
Check the oil bottle level often during the first tank of fuel. If the oil
level doesn't go down, contact your dealer immediately.
Drive Belt/QUICKDRIVE Belt Break-In
The length of the break-in period varies depending on the type of drive
system. The break-in period for a new drive belt is 30 miles (48 km).
The break-in period for a new QUICKDRIVE belt is 100 miles (160
km).
• During the break-in period, vary the throttle position under 50% and
limit full throttle 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.
QUICKDRIVE Belt
During the 100 miles (160 km) of belt break-in, the rider will hear a
sound made by the drive system. After the break-in period, the sound
will become similar to that of a traditional chaincase.
During the break-in period, this belt will shed a fiber-type material in
and around the drive system. Use a dry shop towel to clean the residue.
