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.
Note: If the emergency stop system is used to stop
the machine as a normal daily event, the breaking
system and belts will prematurely wear and require
replacement. When shutting down the machine under
non-emergency conditions, use the red OFF push
buttons.
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 panels.
3. Remove the screws and the safety cover for access
to the upper pulley. See Figures 38 and 39.
4. Use a 14mm wrench and remove the upper caliper
anchor pin retaining nut and washer. See Figure 40.
5. Use locking pliers to clamp on the anchor pin end,
pull the pin from the caliper mount, and remove the
springs. See Figure 40.
6. Pivot the caliper down and away from the rotor for
belt clearance.
7. Remove the upper belt adjustment nut and washer
( Figure 40).
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 belt as necessary.
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. See V- Belt Tension on
Page 29 for details.
12. Reassemble in reverse order and test the emergency
brake operation.
