| 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 Driving Uphill. |
| Driving at low RPM or ground speed 5–11 km/h (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 the PVT System Drying section for details). Prevent water from entering the PVT intake duct. See Intake Pre-Filters for more information. Inspect clutch seals for damage if repeated leaking occurs. |
| Clutch malfunction | Your dealer can assist. |
| Poor engine performance | Check for fouled plug or foreign material in gas tank or fuel lines. Your POLARIS dealer can assist. |
| Slippage from failure to warm up belt | Always warm up the belt by operating below 48 km/h for 1.6 km (30 mph for one mile). Warm up for 8 km (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. |
