TRACK WARM-UP
A loose track or flying debris could cause serious injury or death. Stand clear of
the front of the snowmobile and the moving track. Never hold the snowmobile
up or stand behind it while warming up the track. Do not use excessive throttle
during warm-up or when the track is free-hanging. Use a stable rear support.
Use of traction products such as studs, ice growsers, etc. will increase the
possibility of track damage and/or failure. This could cause loss of control,
resulting in serious injury or death. Always inspect for track damage before
Follow these steps to ensure proper warm-up of the engine, drive train and
track.
1. Use an appropriate stand to securely support the rear of the snowmobile at
the rear bumper. The track should be about 4 inches (10 cm) off the ground.
2. Start the engine and allow it to warm up two to three minutes.
3. Depress the throttle abruptly and allow the track to rotate several revolutions.
It will take longer to warm up the track sufficiently during colder outdoor
4. Release the throttle, apply the brakes, shut off the engine and lower the
snowmobile to the ground.
5. Grasp the skis by their front loops and move them from side to side to loosen
snow and ice.
SLIDE RAIL AND TRACK COOLING
Inadequate cooling and lubrication will lead to overheating of the slide rail and
track, resulting in premature wear and failure. Reduce speeds and frequently
drive into fresh snow to allow adequate cooling and polishing of the slide rail
and track surfaces. Avoid operating on ice, hard-packed surfaces or roads.
