INCRA Miter 3000 - Manual (Page 3)

Now pivot the rear actuator to engage the right-hand tooth with
the notch marked "CAL" on the rear scale, Fig. 9. If adjusted
properly, it will pivot perfectly into the notch. To adjust, loosen the
(3) socket head
screws that
secure the tooth
and fine-tune
the position to
align with the
"CAL" notch.
Pivot back and
forth between
the two "CAL"
notches to
verify the
calibration.
Adjust Fence Mounting Bracket 90° to Saw Blade
Loosen the large clamping knob and make sure that the
rear actuator left-hand tooth is engaged firmly with the 0°
notch on the
1 ⁄ 2 ° adjustment plate. Engage the front
actuator tooth
with the 0°
notch located
on the
protractor
head, Fig. 6.
Tighten the
front actuator
thumbscrew
then tighten
the large
clamping knob.
Calibrating the 1/2° Indexing Tooth
The 1 ⁄ 2 ° indexing tooth located on the rear actuator is
factory calibrated and should require no further
adjustment. Follow the instructions below should you wish to
check the calibration or re-calibrate.
Loosen the large clamping knob and the rear actuator
thumbscrew.
Engage the
left-hand tooth
of the rear
actuator firmly
with the notch
marked "CAL"
on the rear
scale and hold
while you
tighten the large
clamping knob,
Fig. 8.
Using the supplied 5 ⁄ 32 " hex key, loosen the (3) socket head
screws that secure the fence mounting bracket to the protractor
head. Unplug your table saw, then use a reliable machinist
square to set
the fence at
90° to the
saw blade,
Fig. 7.
Tighten the
(3) socket
head screws.

Adjust the Miter Bar
Adjust the miter bar at each of the (8) expansion
mechanism locations for a good fit in your table saw's
miter slot. Turning the screw clockwise expands the
mechanism. You'll find (3) of the expansion locations in front of
the fence and (1) underneath the fence. (You'll need to remove
the fence for access.) Adjust these (4) front expansion points
first, expanding a little at each of the locations until the bar slides
smoothly, Fig. 4.
This one-time calibration prepares your INCRA Miter 3000 for
work in either miter slot. Just remember that the accuracy of the
INCRA Miter 3000 at any subsequent setting is dependent upon
the accuracy of your initial 90° calibration. Verify this important
calibration with a test cut and fine tune as necessary.

Remove the large clamping knob and disengage the rear actuator
tooth from the
1 ⁄ 2 ° adjustment plate. Pivot the protractor head to
gain access to (3) of the rear expansion points. To gain access to
the final rear expansion point, remove the rear actuator
thumbscrew and pivot the actuator, Fig. 5. After adjustment,
replace the rear actuator thumbscrew, re-engage the rear actuator
tooth to the 0° notch on the
1 ⁄ 2 ° adjustment plate, then replace
the large clamping knob, washer and fence.
