5.
Pull and hold the spring-loaded index pin
(see Figure 22) outward approximately
disengage it while you rotate the headstock
to the desired angle as shown by the digital
protractor.
Note: The spring-loaded index pin serves
only as a quick way to return or position the
headstock close to zero, or 45° to the left or
right. It is not intended to be an exact angle
stop.
6.
Snug the three hex nuts in place.
7.
Place the appropriate angle finding tooling
on the workpiece or milling table, and fine-
tune your angle adjustment and alignments
according to standard machine shop prac-
tices.
8.
When satisfied with the position of the head-
stock, tighten the three hex nuts, and recheck
your settings.
Note: As described earlier in the manual, the
digital protractor is equipped with an auto-
shutoff feature. So if during setup or milling
operations it shuts OFF, your angle setting
is retained in volatile memory. When the pro-
tractor is needed again, push the ON/OFF
button and the digital display will retrieve and
show the last angle or grade measured.
