TROUBLESHOOTING
Drive Belt Wear/Burn
Possible Cause Solution
Driving onto a pickup or
tall trailer in high range Use low range during loading.
Starting out going up a
steep incline Use low range. See warnings on page 60.
Driving at low RPM or
ground speed (3-7 MPH) Drive at a higher speed or use low range more frequently.
Insufficient warm-up at
low ambient
temperatures Warm the engine at least 5 minutes. With the transmission
in neutral, advance the throttle to about 1/8 throttle in
short bursts, 5 to 7 times. The belt will become more
flexible and prevent belt burning.
Slow/easy clutch
engagement Use the throttle quickly and effectively.
Towing/pushing at low
RPM/low ground speed Use low range only.
Utility use/plowing Use low range only.
Stuck in mud or snow Shift the transmission to low range and carefully use fast,
aggressive throttle application to engage clutch.
WARNING: Excessive throttle may cause loss of control
and vehicle rollover.
Climbing over large
objects from a stopped
position Shift the transmission to low range and carefully use fast,
brief, aggressive throttle application to engage clutch.
WARNING: Excessive throttle may cause loss of control
and vehicle rollover.
Belt slippage from water
or snow ingestion into the
PVT system Dry out the PVT (see page 105). Prevent water from
entering the PVT intake duct (see page 107). Inspect
clutch seals for damage if repeated leaking occurs.
Clutch malfunction See your POLARIS dealer.
Poor engine performance Check for fouled plug or foreign material in gas tank or
fuel lines. See your POLARIS dealer.
Slippage from failure to
warm up belt Always warm up the belt by operating below 30 mph for
one mile (5 miles or more when temperature is below
freezing).
Wrong or missing belt Install the recommended belt.
Improper break-in Always break in a new belt and/or clutch. See page 49.
