OPERATIONS
To achieve the best sanding results experiment with
conveyor feed rate, sanding depth, various grits of
sandpaper, and oscillation speed.
To sand a workpiece, do these steps:
1. Measure the workpiece and record the thickest spot.
1. With the table already calibrated, turn the sander
ON, set the feed rate.
4. Type in the thickness of your workpiece using the
numeric key pad (Example: for a 2" thick workpiece
type 2.000"), and press the table start key:
Note: The upper left corner input LED will
illuminate (See Figure 20), and the display numbers
will flash when entering measurements.
5. Measure the sanding depth needed. Example: let’s
say you need 1⁄64 ". Note: Removing too much
material can burn the workpiece, tear the paper, or
give poor sanding results.
6. Convert 1⁄64" fraction to a 0.016" decimal
measurement using the conversion table on the
sander.
7. Calculate the resulting workpiece thickness (2.000"—
0.016" = 1.984"), and type that thickness (1.984") on
the key pad.
8. Pressthetablestartkey: The table will raise to
the new setting.
Note: The computer rounds the sanding thickness
measurements in increments of 0.005".
Note: The lower left corner Run LED will illuminate
and the display numbers will glow steadily when
measurements have been accepted and the table is
auto-adjusting. When the correct sanding depth is
achieved, the lower left corner Run LED will turn
off and the final resulting workpiece thickness is
displayed.
10. Start the conveyor, stand to the side as shown in
Figure 22, and feed the workpiece into the sander.
11. Observe the amp draw meter, and press the table
down arrow key on the key pad to reduce the
sanding depth if the amp load meter indicates motor
overload.
12. Remove the workpiece from the outfeed side, which
is now sanded down 1⁄64".Re-sandtheworkpiece
a couple of times more at this depth to ensure a
consistent sanding depth.

7 and 8, and sand again.

Basic Sanding
For best results when finish sanding,
feed each piece through the sander
two or three times without adjusting
the depth of cut. Turn the workpiece
180˚andfeed itthrough twoor three
more times at this same depth. As
always, use your best judgement. If
you no longer hear the sanding belt
making contact with the workpiece on
successive cuts, then no further passes
are needed at that depth.
