TROUBLESHOOTING
Drive Belt Wear/Burn
Possible Cause Solution
Starting out going up a
steep incline Use low range (if equipped) or turn around using the K-
turn (see page 49).
Driving at low RPM or
ground speed (3-7 MPH) Drive at a higher speed or use low range (if equipped)
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 (if equipped).
Utility use/plowing Use low range only (if equipped).
Stuck in mud or snow Shift the transmission to low range (if equipped). Care-
fully 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 89. Inspect clutch seals for
damage if repeated leaking occurs.
Clutch malfunction See your Polaris dealer.
Poor engine performance Check for fouled plugs or foreign material in gas tank,
fuel lines or carburetor. See your dealer.
Slippage from failure to
warm up belt Always warm up the belt by operating below 30 mph (48
km/h) for one mile (1.6 km). Operate 5 miles (8 km) 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 37.
