8. Connect the sander to the power source
and make note of the reading on the digital
display. Then manually lower the table an
additional 0.020" to 0.030". This is how much
lower the outfeed pressure roller should
be set when compared to the height of the
infeed roller.
9. Loosen the roller lock nuts on the outfeed
pressure roller. Turn the adjustment bolts to
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 and recheck your
settings.
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. Some
experimentation may be necessary to achieve
the desired results. However, under no circum-
stances should the pressure rollers be set even,
or higher than, the sanding roller.
7. Tighten the roller lock nuts and recheck your
settings.
3. Turn the adjustment nut up or down until the
V-belts deflect 1" off of center when pushed
with your finger.
