7. Tighten the roller lock nuts.
8. Connect power to the sander and observe
the reading on the digital display. Then man-
ually lower the table an additional 0.020" to
0.030".
9. Loosen the roller lock nuts on the outfeed
pressure roller. Turn the adjustment bolts
and lower the pressure roller until it just
touches the board.
Note: DO NOT continue
to lower the roller beyond that point.
10. Tighten the roller lock nuts.
Note: Variables such as feed rate, depth of
the cut, and the type of sanding belt can play
a big part in determining the proper amount
of downward pressure exerted by the rollers.
Experimentation is necessary to get the desired
results. However, under no circumstances should
the pressure rollers be set even, or higher than,
the sanding roller.
3. Turn the adjustment nut up or down until the
V-belts deflect 1" off of center when pushed
with your finger.
4. Retighten the lock nut.
