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.
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.

immediately stop in the event of an emergency!
