GETTING TO KNOW YOUR DIGITAL MITER GAUGE
The digital miter gauge is a smart tool that increases efciency in woodworking projects. It was designed by a professional
woodworker for woodworkers. It sets crosscut angles and table saw blade angles from -50° to +50° with ±0.1° accuracy in
a matter of seconds. For use with all bench, portable, and stationary table saws with 1/2", 5/8", and 3/4" slots and 5/8", 3/4",
and 7/8" T-Slots with the slot depth of 3/8" or 1/2".

CHOOSE THE PROPER GAUGE BAR ATTACHMENT
Fig. 6
The gauge bar attachments adapt the universal gauge bar
to t in standard 1/2”, 5/8” or 3/4” miter gauge slots. The
universal gauge bar ts a 1/2” slot. Using the hex wrench
and the screws provided, attach a 1/8” gauge bar attachment on the side to t in a 5/8” slot; attach a 1/4” gauge
bar attachment on the side to t in a 3/4” slot. Please refer
to Fig. 6.
ADJUST THE T-SLOT WASHER TO THE CORRECT POSITION
Adjust the T-slot washer to allow the gauge bar to t in the
slots of T-slot tables and non T-slot tables on bench, portable, and stationary tools.
The 3/8” T-slot washer (Fig. 7a) is attached to the front side
of the gauge bar (Fig. 8). Use this washer for T-slots that
are 3/8” deep. For T-slots that are ½” deep, remove the
3/8” washer and attach the ½” T-slot washer (Fig. 7b & Fig.
7c).
There are three indicating lines on each washer (Fig. 7a);
use these lines to guide you as you turn the washer to a
specied position to it t a standard 5/8”, 3/4” or 7/8” Tslot table.
Fig. 8
To t non T- slot tables, keep the two sides of the T-washer
aligned with the gauge bar, as shown in Fig. 8.

CALIBRATE THE DIGITAL MITER GAUGE TO
THE TABLE-SAW BLADE ASSEMBLY
(Carpenter’s square, available separately, required)
NOTE:
•Alwayscalibratethedigitalmitergaugetoyourtablesaw
before using this miter gauge to guide a cut. Failure to
perform the calibration may result in an inaccurate cutting.
•Oncethedigitalmitergaugehasbeencalibratedtoyour
table saw, no additional calibration is needed with subsequent use on the same table saw, unless the miter gauge
was calibrated to other table saws or carpenter’s square
after the rst calibration.
1. Slide the gauge bar into the groove on the T-slot in the
table or place the bar in the groove on a non T-slot table.
2. Fully raise the table-saw blade.
3. Loosen the locking handle.
4. Turn the miter gauge on.
3. Tighten the screw again with the hex wrench.
TURN THE DIGITAL MITER GAUGE ON AND
OFF
1. Press the Power button to turn on the tool.
2. Press the Power button for about 3 seconds to turn off
the tool.
3. The digital miter gauge will automatically turn itself off 5
minutes after the user stops moving the miter gauge
head.
FLIP THE DISPLAY
After the digital miter gauge is turned on, briey press the
Power key to ip the display.

5. Place a carpenter’s square rmly against the blade and
the miter fence (Fig. 12).
6. Press the Zero button for 2 seconds; the LCD will display
0.0º. The miter gauge is now calibrated to your table saw.
You may proceed to use the digital miter gauge for angle
cutting.
AUDIO FEEDBACK
During operation, the digital miter gauge produces an audible “click” as it swivels to the left or to the right. This feature
alerts the operator that the digital miter gauge is working
properly.

CUT WOOD AT ANY ANGLE WITH ±0.1º ACCURACY
WARNING:
Always keep the miter fence away from the blade when
guiding the cut with this digital miter gauge. Serious
personal injury may result if the metal fence is cut.
NOTE:
Before making any cuts, the digital miter gauge must rst be
calibrated.
1. Fit and calibrate the digital miter gauge to the table as
described in the preceding section, "CALIBRATE THE
DIGITAL MITER GAUGE TO THE TABLE-SAW-BLADE
ASSEMBLY.”
2. With the miter gauge bar securely in the table groove, turn
the digital miter gauge on.
3. Unlock the locking handle.
4. Swivel the miter gauge head to the desired angle, as indi-
cated in the display, and then tighten the locking handle.
USE THE PRECISION FENCE ACCESSORIES
This digital miter gauge offers a variety of precision fence
accessories which will allow the user to fully utilize the miter
gauge capabilities.
Fig.14
The precision stop gauge is designed for vertical precision;
it allows the user to cut multiple pieces with one pass, as
shown in Fig. 14.
5. Securely place the workpiece against the miter fence and
begin crosscutting, following the operating instructions
for the table saw (Fig. 13).
Fig.15
Fig.13
Fig.16
The Flip Stop Gauge is a multiuse gauge, which can be used
in the top fence groove and as a solid stop gauge. To cut a
long workpiece, just ip it back, there is no need to detach it
from the fence (Fig. 15 and 16).

The Micro-adjust Gauge is designed to be used in any of the
fence grooves; it can be used as a micro-adjust for the ip
stop or as a positive stop gauge. To adjust the ip stop
gauge, rst lock the micro-adjust gauge on the fence with
the lock knob, then turn the micro-adjust screw to move the
ip stop gauge left or right (Fig. 17).
SET THE TABLE-SAW BLADE TILT ANGLE
WARNING:
Before setting blade-tilt angle, make sure that the table-saw switch is in the OFF position and the plug is
not connected to a power source. Serious personal injury may result if the saw is accidentally started.
WARNING:
Remove the hex wrench from the locking handle and
put it in a safe place.
Serious personal injury may result if the hex wrench falls
into the table saw.
The magnetic blade attachment properly ts only the 1/2”
gauge bar, so detach any gauge bar attachment that is on
the gauge bar.
Use the magnetic blade attachment for table saw blades
that bevel to either the the left or the right.
1. Use the 1/8-in. hex wrench (included) to loosen the setscrew in the magnetic blade attachment in the counterclockwise direction.
2. For table saw blades that tilt "left," the magnets on the
attachment need to be oriented to the right side of the
gauge bar, as in Fig. 18. For table saw blades that tilt
"right," the magnets need to be oriented to the left side of
the gauge bar.
3. Tighten the setscrew.
4. Loosen the locking handle clockwise.
Fig.19
5. Place a carpenter’s square rmly against the magnetic
attachment and the miter fence. Press the Power button
to turn the digital miter gauge on. Press the Zero button
for 2 seconds to calibrate the gauge: the LCD will display
0.0º (Fig. 19).
6. Remove the table-saw insert.
7. Lower the table-saw blade to its lowest setting.
8. Loosen the fence-lock knobs and slide the miter gauge
head to the middle of the miter fence. Retighten the fencelock knobs.

9. Lower the gauge bar into the table-saw-blade assembly
opening and allow the magnets to attach to the blade.
Always position the magnetic blade attachment close to
the center of the blade to keep the gauge bar from contacting the lower guard. Do not tighten the locking handle
(Fig. 20 and 21).
NOTE:
Be careful not to place the magnets near or on the saw blade
teeth.
10. Set the blade tilt angle by using your table saw controls
to adjust the blade to the desired angle, as indicated in
the miter-gauge display. If desired, ip the display by
briey pressing the Power button again.
NOTE:
In the process of moving the blade, ensure that the magnets
are always attached to the blade. If the magnets separate
from the blade, an inaccurate setting will result.
11. Remove the miter gauge and replace the table-saw in-
sert according to the table saw’s instruction manual before beginning to cut.
