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.
