TROUBLESHOOTING

Drive Belt Wear/Burn

Possible Cause

Solution

Driving at low RPM or 

ground speed

Drive at a higher speed.

Insufficient warm-up at 

low ambient 

temperatures

Warm the engine at least 5 minutes. With the 

transmission in neutral, apply small amount of 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.

Belt slippage from water 

or snow ingestion into 

the CVT system

Dry out the CVT (see page 75). Prevent water from 

entering the CVT inlet and outlet ducts (see page 93). 

Inspect clutch seals for damage if repeated leaking 

occurs.

Clutch malfunction

Your POLARIS dealer can assist.

Poor engine 

performance

Check for fouled plug or foreign material in gas tank or 

fuel lines. Your POLARIS dealer can assist.

Wrong or missing belt

Install the recommended belt.

Improper break-in

Always break in a new belt and/or clutch. See page 41.
