Adjusting the Track Tension
Check and adjust the track tension after the first
50 operating hours and every 100 operating hours
thereafter. There should be 2-3/4 inches (7 cm)
between the tension nut and the back of the
tension tube (Figure 37). If not, adjust the track
tension using the following procedure:
