V-Belt Tension

The sanding motor (Figure 41) and table lift motor (Figure 42) V-belts must be tensioned properly for best performance. No adjustment is necessary for the conveyor motor belt, as it uses a variable width pulley. See Figure 43. Only replace the belt if it becomes frayed, cracked, or glazed. If one belt is bad, always replace both belts as a matched set. Both table lift and sanding motor belts are adjusted the same way.

KEEP the sanding drum drive belts correctly adjusted. If the belts are loose, and the emergency stop is engaged, the sanding drum pulley will slip and not immediately stop in the event of an emergency!

To tension the V-belts, do these steps:

1.TURN OFF and LOCK the master power switch so your sander cannot accidently start!

2.Remove the lower cover(s) on the sander (right cover for sanding belt motor; left cover for the conveyor height motor).

3.Turn both tension adjustment nuts clockwise to tighten the V-belts, or turn both nuts counterclockwise to loosen the V-belts.

4.The V-belt is properly tightened when it will move no more than 3⁄4" in the center with moderate pressure from your thumb.
