Incra 3000 用户指南

4

The dual actuator design of the INCRA Miter 3000 provides two
levels of adjustment. The front actuator is used for coarse
adjustments (5°), while the rear actuator is used for fine
adjustments (

1

⁄

2

°). For most mitering work, you'll have the

left- hand tooth of the rear actuator engaged at 0°, while you
make angle changes using only the front actuator. When using
the rear actuator for fine adjustments, you are simply adding or
subtracting from the coarse adjustment setting.

Rotate the protractor head to the desired angle, then
firmly engage the tooth on the front actuator with the
corresponding notch on the protractor head. The actuator

tooth should point directly to the desired angle on the scale.
Tighten the large clamping knob, then tighten the front actuator
thumbscrew, Fig. 11.

Loosen the large clamping knob and make sure that the
rear actuator left hand tooth is engaged in the 0° notch on
the 

1

⁄

2

° adjustment plate. Loosen the front actuator

thumbscrew and pivot the actuator tooth away from the notches
located on the protractor head, Fig. 10.

Loosen the large clamping knob. Loosen the front
actuator thumbscrew and pivot the actuator tooth away
from the notches located on the protractor head. Rotate

the protractor head and engage the front actuator tooth at the 5°
notch closest to the angle you want. Tighten the front actuator
thumbscrew, Fig. 12.

Loosen the rear actuator thumbscrew. Use the left-hand
tooth to add or subtract from the coarse adjustment setting
in 1° intervals. Use the right-hand tooth to add or subtract

from the coarse adjustment setting in 

1

⁄

2

° increments. Engage

the tooth firmly in the selected notch, then tighten the large
clamping knob and the rear actuator thumbscrew, Fig. 13.
Important: After completing your cut, don't forget to return the
rear actuator setting to the 0° notch.

For angle settings finer than the 

1

⁄

2

° settings, first use the 

1

⁄

2

°

indexing instructions above to locate the protractor head as close
as possible to the desired angle. With the large clamping knob
loosened, pivot the rear actuator tooth slightly away from the
notch on the 

1

⁄

2

° adjustment plate. Rotate the protractor head in

the direction of required adjustment and tighten the large
clamping knob. Do not tighten the rear actuator thumbscrew. As
with any mitering tool, odd angle adjustments may require a little
trial and error.
