make note of the reading on the digital dis-
play. Then manually lower the table an addi-

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 down-
ward 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
with, or higher than, the sanding roller.
To adjust the pressure rollers:
1. Disconnect the sander from the power
source!
2. Plane (2) 36" long 2x4’s to a uniform thick-
nesses. Place one board along the length of
the feed belt on the right-hand side and place
the other board on the left-hand side.
3. With the sanding belt tensioned (Figure 21),
grab the edge of the sanding belt and move
it up and down about an inch or so. At the
same time, manually raise the table until you
just hear the sandpaper make contact with
the surface of the wood. DO NOT continue to
raise the table beyond that point.
4. Connect the sander to the power source and
make note of the reading on the digital dis-
play. Then manually lower the table 0.020" to
0.030". This is how much lower the infeed
pressure roller should be set when compared
to the sanding surface of the sanding roller.
