G0527 18" Wide Belt Sander -27-
Calibration
NOTICE
The digital thickness gauge has been cali-
brated at the factory and should require no
further adjustment, however, we recom-
mend verifying its accuracy.
The first board fed through the sander will be
used to test the accuracy of the digital thickness
gauge.
To calibrate the digital thickness scale:
1. Follow the start up procedures from
Section 5: Set Up beginning on page 12.
2. Using a properly set-up planer, plane a board
to uniform thickness.
3. Lower the sander table far enough to place
the planed board under the sander roller.
4. Manually raise the table until the board just
touches the sanding roller.
5. Remove the board without changing the
table height. This ensures the table will be
properly adjusted for the first sanding pass.
6. 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.
7. Using a precise micrometer or set of calipers,
measure the thickness at various points
around the board.
8. Continue sanding the board until the average
thickness measurement is within
+
⁄-0.003".
Note—The final several passes should be
done without adjusting the table height. This
ensures the most consistent average thick-
ness.
9. Make note of the digital display read-out. It
should be the same as the average thickness
of the sanded wood.
— If they are the same, the sander is prop-
erly calibrated and accurate to the near-
est 0.001". Continue to the next sub-sec-
tion.
— If the digital display readout is not the
same, recalibration is needed. Continue
on to step 10.
10. Without moving the table height, enter the
numerical measurement of the average
thickness 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.
11. Press and hold the SET key until the display
stops flashing. The sander is now correctly
calibrated.
