OPERATION
Track Warm-Up
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
approximately 4″ (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. NOTE: It will take longer to warm up the track
sufficiently during colder outdoor temperatures.
4. Release the throttle, apply the brakes, shut off the engine and lower
the machine to the ground.
5. Grasp the skis by their front loops and move them from side to
side. This will loosen frozen snow from the ski bottoms, allowing
the machine to move forward more easily.
6. The engine, drive system and track are now properly warmed up
and the machine may be driven following normal safety practices.
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.
CAUTION
A loose track or flying debris could cause serious personal injury
or death. Stand clear of the front of the machine 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. Be sure the rear
support is stable.
