TROUBLESHOOTING
Drive Belt Wear/Burn
Possible Cause Solution
Driving onto a pickup or
tall trailer in high range Use low range.
Starting out going up a
steep incline Use low range or turn around using the K-turn (see page
52).
Driving at low RPM or
ground speed (5-11 kmh) Drive at a higher speed or use low range more frequently.
Insufficient warm-up at
low ambient tempera-
tures 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 flex-
ible and prevent belt burning.
Slow/easy clutch engage-
ment 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. Carefully use fast,
aggressive throttle application to engage clutch.
WARNING: Excessive throttle may cause loss of control
and vehicle overturn.
Climbing over large
objects from a stopped
position
Belt slippage from water
or snow ingestion into the
PVT system Dry out the PVT. See page 111. Inspect clutch seals for
damage if repeated leaking occurs.
Clutch malfunction See your POLARIS dealer.
Slippage from failure to
warm up belt Always warm up the belt by operating below 40 km/h for
1.5 km (8 km or more when temperature is below freez-
ing).
Poor engine performance Check for fouled plugs or foreign material in gas tank or
fuel lines. See your dealer.
Wrong or missing belt Install the recommended belt.
Improper break-in Always break in a new belt and/or clutch. See page 42.
