Changing V-Belts
Check the V-belts periodically to check for
signs of glazing, cracking or fraying. If any of
these conditions are present, change both V-
belts.
To change the V-belts, do these steps:
1. TURN-OFF and LOCK the master power
switch so no power can go to your sander
and shut off the air pressure!
2. Open both right-side upper and lower
access covers.
3. Remove the two screws and the safety
cover for access to the upper pulley. See
Figures 37.
4. Use a 14mm wrench and remove the upper
caliper anchor pin retaining nut and
washer. See
Figure 38.
5. Use ViceGrip ® or similar pliers to clamp on
the anchor pin end and pull the pin from
the caliper mount and remove the springs.
See
Figure 38.
6. Pivot the caliper down and away from the
rotor for belt clearance.
7. Remove the upper belt adjustment nut and
washer. See
Figure 38.
8. Pry the motor base plate upward to de-
tension the belts and roll the belts off of
the motor pulley.
9. Install the new V-belts.
10. Replace the upper belt adjustment nut and
washer, and tension the belts.
11. The V-belt is properly tensioned when it
will move no more than 3 ⁄
4
" in the center
with moderate pressure from your thumb.

emergency brake operation.
