90° Chisel to Worktable Calibration
Referring to Figure 7:
Place a square (E) so it rests against the
worktable (B) and chisel (A). If the chisel to
table angle is 90°, no calibration is necessary.
If calibration is required:
1. Loosen the bolt (C) that allows the tilting
base to pivot.
The tilting base is heavy. If
raised, take extra precaution not to let it
drop on hands or fingers. Injury can result.
2. Adjust the adjustment screws (F) until the
chisel to table angle is 90°. Calibration is
then complete.
3. Retighten the bolt (C).
Upon completion, make sure that the pointer
points to 0°. Calibrate if necessary.
Chuck Extension Adaptor
The provided Chuck Extension Adaptor (C) is
intended to lower the chuck for use with
after-market chisels (chisels other than the
POWERMATIC brand) that may require a
spacer due to varying lengths in shanks.
To install the adaptor, first remove the chisel
and bit (see the Installing Chisel and Bit
section). Then, referring to Figure 8:
1. Loosen the lock screw (E) enough to
remove the chisel bushing (F).
2. Remove the chisel bushing (F). This is
necessary to provide enough clearance
when installing the chuck and extension
adaptor.
3. Unscrew the chuck release nut (A)
counterclockwise with the wrench provided
to force the chuck (D) off the shaft (B).
It may be necessary to hold the shaft
stationary while turning the nut. This can
be done by inserting the chuck key handle
into the hole in the chuck and allowing it to
wedge against the edge of the headstock.
4. When the chuck is off, return the chuck
release nut (A) to its original position on the
shaft (B).
5. Push the adaptor (C) into the chuck (D).
Then push this assembly onto the motor
shaft (B).
