W1756/W1757 43" Wide-Belt Sander
SERVICE
Table Limit SwitchesThe table limit switches prevent the table lift motor
from driving the table into the sanding drum. Periodically
check and adjust (if required) the table stop switches to
protect the feed belt.
To adjust table limit switches, do these steps:
1. Supply air to the sander and tension the sanding
belt.
2. Push the down arrow key and lower the table until
you achieve six inches between the sanding drum
and the feed belt table surface.
3. Loosen the mounting bolts for the table-down limit
switch and slide the switch so the switch plunger
depresses against the stop block and you hear the
switch click (see Figure 31).
4. Re-tighten the mounting bolts.
5. Push the up arrow key and raise the table until it is
1⁄8" below the sanding drum.
6. Loosen the mounting bolts for the table-up limit
switch, and move the switch so the switch plunger
depresses against the stop block and you hear the
switch click (see Figure 31).
7. Re-tighten the mounting bolts.
8. With the sanding belt OFF, use the up and down
buttons to test the table operation and make sure
the switches shut the table lift motor OFF when
the table is at the minimum and maximum distance
from the sanding drum.
