13.15 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.

13.16 Steady Rest Adjustment

Always grease the fingers before using the
steady rest. The point at which the fingers
contact the workpiece
lubrication to prevent premature wear.
To set the steady rest (see Figure 52):
1. Loosen the hex nut (A) at the base of the
steady rest, to slide the steady rest along
the ways.
require continuous
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

13.17 Follow Rest Adjustment

The follow rest mounts to the saddle with two
socket head cap bolts. The follow rest should be
mounted so that the locking knobs point away

The sliding fingers are set similar to those on the
steady rest – free of play, but not binding.
Always lubricate the fingers sufficiently with
grease before operating.
