TROUBLESHOOTING

Drive Belt Wear/Burn

Cause

Solution 

Driving at low RPM

Drive at higher RPM. Gear the machine down. Check belt 

deflection.

Insufficient warm-up

Warm the engine at least five minutes. Take the drive belt 

off the machine in extremely cold weather and warm it 

up. Break machine loose from the snow.

Towing at low RPM

Do not tow in deep snow. Use fast, aggressive throttle to 

engage clutch.

Riding with high RPM 

and slow speed (8000 

RPM/10 MPH)

Lower the gear ratio. Reduce RPM. Avoid riding in high 

ambient temperatures. Check for snow ingestion.

Ice and snow build-up 

between track and tunnel

Warm the engine at least five minutes. Take the drive belt 

off the machine in extremely cold weather and warm it 

up. Break machine loose from the snow.

Poor engine performance Check for fouled plugs or water, ice, or dirt in the gas tank 

or fuel line.

Loading machines onto 

trailers

Skis may gouge into trailers and prevent the drivetrain 

from spinning properly. Use enough speed to drive the 

machine completely onto the trailer. Push and pull it to 

finish loading if necessary.

Clutch malfunction

Inspect clutch components. See your dealer.

Slow, easy clutch engage-

ment

Use fast, aggressive throttle to engage clutch.

Wrong or missing belt

Always use the recommended belt.

Improper break-in

Always break in a new belt and/or clutch by avoiding 

aggressive or high speed operation during the break-in 

period.
