NOTE: After a long period of time, adjustments may be necessary to maintain the tension and tracking of the sanding belt. If the belt will not hold its tension, tighten the set screw (G) Fig. 22. If the belt will not hold its tracking, tighten the set screw (F) Fig. 22.

Make only small adjustments to these screws. Over-tightening will lock the tension lever and/or the tracking knob.
