Drive at higher RPMs. Gear the machine down.
Check belt deflection.
Warm the engine at least five minutes. Put the
transmission in neutral to warm belt. In extreme
cold weather, take the drive belt off the snowmobile
and warm it up. Break snowmobile loose from the
snow.
Do not tow in deep snow. Use fast, aggressive
throttle to engage clutch.
Lower the gear ratio. Reduce RPM. Avoid riding in
high ambient temperatures. Check for snow
ingestion.
Warm the engine at least five minutes. Take the
drive belt off the snowmobile in extremely cold
weather and warm it up. Break snowmobile loose
from the snow.
Check for fouled plugs and water, ice or dirt in the
fuel tank or fuel line.
Skis may gouge into trailers and prevent the
drivetrain from spinning properly. Use enough
speed to drive the snowmobile completely onto the
trailer. Push and pull it to finish loading if necessary.
Inspect clutch components. Your dealer can
perform this service.
