TROUBLESHOOTING
Drive Belt and Cover Problems
Possible Cause Solution
Driving the ATV onto a
pickup or tall trailer in
high range.
Shift transmission to low range during loading of the ATV
to prevent belt burning.
Starting out going up a
steep incline.
When starting out on an incline, use low range or dis-
mount the ATV (after first applying the park brake) and
perform the K-turn as described on page 66.
Driving at low RPM or
low ground speed (at
approximately 3-7 MPH).
Drive at a higher speed or use low range more frequently.
The use of low range is highly recommended for cooler
PVT operating temperatures and longer component life.
Insufficient warm-up of
ATVs exposed to low am-
bient temperatures.
Warm the engine at least 5 minutes. With the transmission
in park, 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 and easy clutch en-
gagement.
Use the throttle quickly and effectively for efficient enga-
gement.
Towing/pushing at low
RPM/low ground speed.
Use low range only.
Utility use/plowing snow,
dirt, etc.
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 overturn.
Climbing over large ob-
jects from a stopped posi-
tion.
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 overturn.
Belt slippage from water
or snow ingestion into the
PVT system.
Shift the transmission to park. Using the throttle, vary the
engine RPM from idle to full throttle. Repeat several
times as required. During this procedure, the throttle
should not be held at the full position for more than 10
seconds. Clutch seals should be inspected for damage if
repeated leaking occurs.
Clutch malfunction. Contact your Polaris dealer for inspection of clutch com-
ponents.
Poor engine performance. Check for fouled plugs or foreign material in gas tank,
fuel lines, or carburetor. Contact your dealer for service.
