ADJUSTMENTS
Figure 16. Tracking safety switch and
adjustment bolt.
Belt tracking safety switches are placed on
both sides of the belt to act as emergency
machine stops if the belt travels too far to one
side during oscillation. See Figure 16.
To adjust the belt tracking safety switches,
do these steps:
1. TURN-OFF and LOCK the master power
switch so no power can go to your sander!
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
16 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.
