Belt tracking limit switches are placed on both sides of

the machine to act as emergency machine stops if the

belt travels too far to one side during oscillation. (see

Figure 34).

To adjust the belt tracking limit switches, do these

steps:

1. DISCONNECT THE SANDER FROM POWER!

2. Make sure the belt tracking and oscillation is

adjusted.

3. Release the belt tension, center the sanding belt on

the top roller, then re-tension the belt.

4. Measure the distance from the edge of the sanding

belt to the ceramic rod protruding from the switch.

5. Loosen the adjustment bolt shown in Figure 34, and

move the switch so the belt and the ceramic rod have

approximately

1

2

" clearance from each other.

6. Tighten the bolt and repeat the adjustment with the

other side if necessary.

7. Start the sander and make sure it is working

properly.
