Operation
Pre-Ride Warm-Up
Always warm up the engine, drive train and track before operating the
snowmobile. Support the rear with an appropriate track stand. The track
should be suspended approximately 4" (10 cm) off the ground.
A loose track or flying debris could cause serious personal injury or death. Be
sure the rear support is stable. Stand clear of the front of the machine and the
moving track. Never hold the snowmobile up or stand behind it while
performing this procedure. Do not use too much throttle during warm-up or
when the track is free-hanging.
1. Start the engine. Allow it to idle for two to three minutes.
2. Engage the drive system abruptly and allow it to rotate the track
several revolutions.
TIP: In colder weather, the track will need a few more revolutions to fully warm it.
3. Stop the engine. Remove the rear support.
4. Grasp the skis by their front loops and move them from side to side
to loosen frozen snow.
