Observe the following precautions: G Do not allow anyone to stand behind the snowmobile when the engine is running. G When the rear of the snowmobile is raised to allow the drive track to spin, a suitable stand must be used to support the rear of the snowmobile. Never allow anyone to hold the rear of the snowmobile off the ground to allow the drive track to spin. Never allow anyone near a rotating drive track. G Inspect the drive track condition frequently. Replace damaged slide metal. Replace the drive track if it is damaged to the depth where fabric reinforcement material is visible or support rods are broken. Otherwise, track damage or failure could result in loss of braking ability and snowmobile control, which could cause an accident. @ Measuring the drive track deflection 1. Lay the snowmobile on its side. 2. Measure the drive track deflection with a spring scale. Pull at the center of the drive track with a force of 100 N (10 kg, 22 lb). NOTE: @ Measure the gap between the slide runner and the edge of the track window. Measure both sides. @ 1 Deflection 2 100 N (10 kg, 22 lb) Standard drive track deflection: For RS90N/RS90R/RS90NR/RS90M/RS90MS/ RS90GT 30-35 mm (1.18-1.38 in) / 100 N (10 kg, 22 lb) For RSG90/RSG90GT 25-30 mm (0.98-1.18 in) / 100 N (10 kg, 22 lb) 3. If the deflection is incorrect, adjust the drive track. 8-31
