Depth Gauge/Depth Stop
Depth Guage
The depth gauge (AA, Figure 18) measures the
distance between the conveyor table and the
sanding drum for thickness dimensioning of
boards.
Depth Gauge Calibration
1. Loosen the locking knob (BB) of the lower
depth gauge support (CC) and lower it so
that it rests on top of the table support (EE).
2. Raise the conveyor table until it touches the
sanding drum. Then loosen the locking knob
(DD) of the upper depth gauge support and
position the “0” mark of the scale even with
the top of the lower depth gauge support.
3. Tighten the upper depth gauge support in
position.
Once calibrated, the locking knob (BB) of the
lower depth gauge support can be loosened,
allowing the lower depth gauge support to ride
on top of the table support. The depth can then
be read where the scale enters the lower depth
gauge support.
Depth Stop
The depth gauge can also be used as a stop
gauge as follows: Position the lower depth
gauge support (CC) along the scale to a desired
finish thickness. Then tighten the lower depth
gauge support with the locking knob to prevent
the conveyor table from being raised above that
point.

Digital Scale
Description
The digital scale can be used to measure the
distance between the conveyor table and the
sanding drum (Absolute measurement) for
thickness dimensioning of boards. It can also be
used to display the amount of material removed
from a sanded board without consideration of
the board's thickness (Relative measurement).
Figure 19 identifies the parts of the digital scale.
The button functions are discussed below,
followed by a section giving practical examples
of how to calibrate your settings, and how these
functions can be used for daily sander
operations.
Before using the device, wipe down the vertical
scale with a dry, soft cloth. Do not use cleaning
solutions. Do not allow any liquids (such as
machine oil) to contact the body of the digital
display. Keep the device clean.
This device uses a 1.5-volt battery cell (SR44 or
G-13A). If it needs replacing, slide off the battery
cover and insert the battery, with the positive
pole of the battery facing out.
Note: After replacing a battery, the digital
display setting defaults to zero and needs to be
reset as described in the Setting the DRO
sections.
ON/OFF
Press ON/OFF button no longer than 3 seconds
to power on.
Press ON/OFF button at least 3 seconds to shut
off the digital display.
Setting the DRO – Absolute Measurement
Setting the DRO sets the distance from the
conveyor table to the sanding drum (Absolute
measurement) which represents the thickness of
the sanded board.
1. Take a board of arbitrary thickness, sand it
and measure the thickness with a caliper.
Make note of this measurement for use
below.
2. Without moving the table, press the SET
button on the DRO – the indicator will flash
“SET”.
3. Press and hold the SET button.
Each digit will flash in turn. When the digit
you want flashes, release the SET button.
4. Press SET button once (no longer than 1
second) and that digit will increase by one
each time SET is pressed.
