OPERATION MANUAL
Positioning Headstock
The head tilts 45° forward or backward and
rotates 90° left or right (see Fig. 19, 20 ).
Any time the head has been tilted or rotated,
you must square the spindle with the table
when setting the headstock back to the 90°
position. This is the only way to ensure preci-
sion milling results later.
