ADULT SECTION
Operation
Pre-Ride Warm-Up
Always warm up the engine, drive train and track before operating the
snowmobile. With the snowmobile securely supported by the rear
bumper with a minimum clearance of 4″ (10 cm) from the ground, use
the following procedure to properly warm up the snowmobile.
WARNING
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 and allow it to warm up two to three minutes.
2. Engage the drive system abruptly and allow it to rotate the track
several revolutions.
NOTE: The outside temperature will determine the amount of track
warm-up required.
3. Shut off the engine and remove the rear support.
4. Grasp the skis by their front loops and move from side to side.
This will loosen frozen snow from the ski bottoms, allowing the
machine to move forward more easily.
5. The engine, drive system and track are now properly warmed up
and the machine can be driven following normal safety practices.
