In order for the scale pointer to be accurate, it
must be calibrated.
We recommend calibrating your scale pointer
any time you adjust the drum height or table lift
screws.
To calibrate the scale pointer:
1. Sand a workpiece with the drum sander
and measure the thickness of the sanded
workpiece.
2. Loosen the screw that secures the scale
pointer and adjust it to the thickness of the
workpiece.

5. Turn the crank handle three full rotations
(counting from the point of actual table move-
ment so handwheel freeplay does not affect
your count) to lower the table so the gauge
blocks are below the pressure rollers, as
shown in
Figure 35.
