OPERATION
Engine and Track Warm-Up
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.
