Table Calibration
Use the first board fed through the sander to test
the accuracy of the digital thickness gauge.
To calibrate the digital thickness scale:
1. Using a properly set-up planer, plane a board
to uniform thickness.
2. Lower the sander table far enough to place
the planed board under the sander roller.
3. Manually raise the table until the board just
touches the sanding roller.
4. Remove the board without changing the
table height. This ensures the table will be
properly adjusted for the first sanding pass.
5. Run the board through the sander several
times at the initial height setting. Manually
raise the table 0.020" and pass the board
through the sander several more times.
Monitor the amperage meter and the result
-
ing load on the sander.
6. Measure the thickness at various points
around the board using a precise microm
-
eter or set of calipers. Continue sanding the
board at that height until the average thick
-
ness measurement is within
+
⁄- 0.003".
Note: These final passes should be done
without adjusting the table height. This
ensures the most consistent average thick
-
ness.
7. Observe the digital display read-out, it should
indicate the average thickness of the sanded
wood.
—If it does, the sander is properly calibrated
and accurate to the nearest 0.005".
—If it does not, you must recalibrate the digital
thickness scale.
To recalibrate the digital thickness scale:
1. Without moving the table height, enter the
numerical measurement of the average thick
-
ness of the sanded wood into the digital key
pad on the control panel.
Note:
The average thickness of the sanded
wood should now be flashing on the digital
read-out.
2. Press and hold the key until the display
stops flashing.
The sander is now correctly
calibrated.
