W1756/W1757 43" Wide-Belt Sander

Sanding Belt Tension

Safety Switch

The belt tension safety switch shuts the sanding motor

OFF

if the belt breaks or has no tension when the lock

flange pushes the belt tension safety switch lever (see

Figures 57

)

To adjust the belt tension safety switch, do these

steps:

DISCONNECT THE SANDER FROM THE POWER SOURCE!

Apply normal system air pressure of 75 PSI, and

tension the belt.

Loosen the mounting screw and position the switch

so the lever is in the center of the lock flange hole.

Re-tighten the screw and test the switch operation.
