OPERATION Track Warm-Up WARNING 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 performing this procedure. Do not use too much throttle during warm up or when track is free-hanging. Be sure the rear support is stable. NOTE: The outside temperature will determine the amount of track warm-up required. With the snowmobile securely supported by the rear bumper, and the track approximately 4″ (10 cm) off the ground, follow these steps to ensure proper warm-up of the engine, drive train, and track. 1 2 3 4 Start the engine and allow it to warm up two to three minutes. Depress the throttle abruptly and allow the track to rotate several revolutions. Release the throttle, apply the brakes, shut off the engine and lower the machine to the ground. 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. 78
