Belt Tracking Limit

Switch

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.
