OPERATION
Pre-ride Warm Up
The following steps must be
taken to ensure proper warm
up of the engine, drive train and
track.
With the snowmobile securely
supported by the rear bumper,
and approximately 4″ (10 cm)
off the ground, use the follow-
ing procedure.
1. Start the engine and allow
it to warm up two to three
minutes.
WARNING
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 track is free-
hanging. A loose track or flying debris could cause serious personal injury or
death.
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.
6. WideTrak models can also be warmed up with the transmission in neutral and
the brake engaged. This will allow the engine to warm without engaging the
drive system. NOTE: This should not last more than five minutes.
WARNING
Engine RPM should be at idle before shifting the transmission.
