Installation on 15" Planer
Refer to Figures 1 and 2.
1. Lower the planer table by rotating the
handwheel (A) counterclockwise. This will
provide unhindered access under the gearbox
during installation.
2. Remove setscrew (B) from the head casting
and the lower socket head cap screw (C) in the
table casting with a 5mm hex wrench.
3. Replace the short setscrew in t he head casting

9. Proc eed to the Alignment section.
Alignment
1. Using line of sight, align the front face of the
scale (M) with the fr ont edge of the r ight front
post (Q).
2. Tighten the nut (F) securi ng the t op brack et (E)
with a 14mm socket wrench.

Installation on a 20" Planer
Reversing the Lock Knob
Referring to Fi gur e 3:
The first step in the installation of the DRO is to
reverse the table lock knob assembly so the lock
knob (A), which i s located on the right side of t he
table as shown in Figure 3, is moved to the left
side.
Proceed as follows:
1. Remove the front lock knob (A) by turning
counterclockwise.
2. Remove the unthreaded lock bushing (B).
3. The bar lock (F) is threaded and i s screwed on
to the lock bolt (bar – it em D). Remove as one
unit from the left side of the table and insert
into the right si de of the tabl e. Make sure that
the bevel on the bar lock (F) rests again st the
column.
4. Insert the unthreaded lock bus hing (B) into the
left side of the table, sliding it onto the
protruding lock bolt (D). Make sure that the
bevel on t he lock bushing ( B) re sts against th e
column.
5. Screw the lock knob (A) clockwise onto the
threaded end of the lock bolt (D) on the left
side of the table. Tighten all the way (locked
position), then turn about 1/2 turn
counterclockwise to unlock.
6. Repeat steps 1–4 for the rear lock knob
assembly.

Functions of the Digital
Scale
Figure 6 identifi es the parts of the digital scale.
The button functions are discussed below,
followed by a section giv ing practical examples
of how to cali brate your sett ings, and how the se
functions can be used for daily planer
operations.
Before using t he device, wipe down the v ertical
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. K eep the devic e cl ean.
This devic e uses a 1. 5-volt batt ery c ell ( SR44 or
G-13A). If it needs replacing, slide off the battery
cover and insert the battery, with the positive
pole of the batter y f aci ng out.
Note: After replacing a battery, the digital
display setti ng defaults to z ero and needs to be
reset as described in the Setting the DRO
section.
ON/OFF
Press ON/OFF button no l onger than 3 second s
to power on.
Press ON/OFF button at least 3 seconds to shut
off the digital displ ay .
Setting The DRO
Setting the DRO sets the distance from the table
to the cutt er head ( Absolute measurement) which
represents the thickness of the planed board.
6. Press SET agai n (no longer than 1 second).
The indicator “SET” disappears and the
value you just i nput is displ ay ed on the LCD.
From this point on, any table movement will be
based off this setti ng. The setting will be kept in
the device’s memory, even when the digital
display is turned off and only needs resetting
after a battery has lost charge and needs
replacing.
Relative Mode
Periodic ally during plani ng operati ons, it may be
desirable to di splay the am ount of mat erial t o be
removed from a previously planed board.
With a planer at the last thickness setti ng for that
board:
1. Press ABS until "INC" appears. This toggles
the DRO from Absolute to Relative mode.
2. Press the ON/O FF button f or less than three
seconds. The digit al display resets to zero.
Raising the table will represent the
additional material to be removed from a
board from the pr ev ious setting.
3. To toggle back to Absolute mode, press
ABS again.
IMPORTANT: Al ways place the di git al display i n
relative (“INC”) mode before tur ning it off. If you
turn it off while in absolute (“ABS”) mode, your
absolute setting wi ll default to zero.
1. Take a board of arbit rary thickness , plane 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 – t he indicator will fl ash
“SET”.
3. Press and hold the SET button.
Each digit will flash in turn. When the digit
you want flashes, release the S E T button.
4. Press SET button once (no longer than 1
second) and that digit will increase by one
each time SET is pressed.
When finished:
5. Press and hold the SET button until indicator
“SET” flashes,
