Cross Slide Nut Adjustment
The cross slide moves via a lead screw which
drives a nut. The nut is a half-split nut, allowing
slight adjustment if the cross slide becomes hard to
move or develops backlash. Backlash is identified
by turning the cross slide handwheel left and right
– if there is a delay before any cross slide
movement, the nut needs adjusting (Refer to
Figure 50).
1. Remove dust cover (3).
2. Loosen set screw (1).
3. Tightensocket head screw (2) until the play is
eliminated.
Do not overtighten, which may
cause excessive wear to components.
4. Retighten set screw (1).
5. Reinstall dust cover.

Shear Pin Replacement
The lead screw and feed shaft are equipped with
shear pins, which are designed to break in order to
protect the drive system against overload. A
broken shear pin must be replaced.
Knock out the broken pin; line up the holes and
insert new pin.

Steady Rest Adjustment
Always grease the fingers before using the steady
rest. The point at which the fingers contact the
workpiece require continuous lubrication to prevent
premature wear.
To set the steady rest (see Figure 51):
1. Loosen the hex nut (A) at the base of the
steady rest, to slide the steady rest along the
ways.
2. Loosen the knurled handle (B) at the side until
it can be pivoted out of the slot.
3. Loosen the three lock knobs (C), and back off
the fingers (D) using the knurled handles.
4. Pivot the collar on its hinge and position the
steady rest around the workpiece.
5. Firmly tighten the hex nut at the base.
6. Set the fingers snugly to the work piece and
secure by tightening the locking knobs.
Fingers should be snug but not overly tight.
