V-Belt Tension
The sanding motor V-belts that drive the
sanding rollers (
Figure 19) and the table lift
motor that adjust table height ( Figure 20),
must be tensioned properly for best
performance. Only replace the belt if it
becomes frayed, cracked, or glazed. If one belt
is bad, always replace both belts as a matched
set. NOTE, 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 power cannot start your sander!
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 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.

KEEP the sanding drum drive belts correctly

drum pulley will slip and not immediately
stop in the event of an emergency!
