2. Rotate drum height handwheel (see Figure
33) until sanding drum is well above conveyor
table, then lower sanding drum, allowing a
gap between workpiece and sanding drum.
Note: When adjusting drum to sand thick-
er workpiece, raise and then lower drum
to remove backlash
mechanism.

3. Turn machine ON and feed workpiece into
sander. SLOWLY lower sanding drum until
workpiece makes light contact with sanding
drum. This is correct height to begin sanding
workpiece. Tighten drum height lock knob to
secure setting.
NOTICE
It is imperative that drum height lock knob
is fully tightened before resuming sand-
ing process. Otherwise, sanding drum will
raise up under pressure from workpiece
and will not evenly sand it.

Digital Depth Gauge
The digital depth gauge offers a precise reading
of the distance between the table and the sanding
drum when it is calibrated correctly. This reading
is most useful when sanding workpieces of the
same thickness, or when matching a thickness to
create identical workpieces.
Press the ON/OFF button to display workpiece
thickness, and the mm/in button to toggle between
millimeters and inches (see Figure 34). The
HOLD button will keep the displayed value from
changing even when the drum height is changed,
while the ABS button will switch to Absolute Value
mode (where the distance from zero is displayed
as a positive value).

The depth gauge will turn ON automatically
whenever drum height is changed. Once desired
workpiece thickness is set, turn the gauge OFF to
conserve the battery.
