The mill headstock head can be raised and low-
ered vertically, or rotated left or right up to 90º
degrees to position the cutting tool next to the
workpiece.
To position the spindle head vertically:
1. Make sure the spindle is stopped and the
work area is free from obstructions before
proceeding.
2. Loosen both column lock levers so that the
headstock can freely slide on the column
(
Figure 41).
3. Rotate the mill height handwheel (Figure 41)
to raise or lower the headstock to the desired
position then lock the levers.

The mill table of the Model G0492 can be moved
in two axes—cross slide and longitudinal feed.
Each of these axes are controlled by graduated
handwheels to accurately position the workpiece
in relation to the tool. To set the power feed for
milling, refer to
Setting Power Feed Rate on
Page 29.
Cross Slide
The cross slide is controlled by the cross slide
handcrank of the lathe shown in
Figure 43.
Longitudinal Feed Control
The longitudinal feed is controlled by the longitu-
dinal handwheel of the lathe, and the lock at the
back of the saddle (see
Figure 43).

The headstock is heavy. Make sure that
you support the headstock before you
loosen the lock nuts. Ignoring this warning
may allow the headstock to uncontrolla-
bly swing over to the right or left causing
injury or severe lathe/mill damage.
4. While supporting the headstock, use a 17mm
wrench and loosen both left and right head-
stock tilt lock nuts (
Figure 42), then tilt the
headstock to your desired angle. Retighten
the lock nuts.
