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 34" in the center with moderate pressure from your thumb.

12.Reassemble in reverse order and test the emergency brake operation.
