Head Lock Handle Position Adjustment
The locked position of the head lock handle is adjustable (Figure
33). To raise or lower the handle position follow the procedure
below:
1. Loosen the 3/4 hex lock nuts.
2. With upper head lock loose, turn studs with screwdriver until
handle is in desired position when the head is locked.
Retighten lock nuts.
LEADSCREW BACKLASH ADJUSTMENT
The amount of backlash between the leadscrew and nut may be
adjusted by tightening or loosening the cap screw through the
bronze leadscrew nut. Access to the leadscrew nut is gained by
removing the rear access door. Tightening the cap screw in the
bronze nut decreases the amount of backlash (Figure 34).

ADJUSTMENT OF THE LEADSCREW NUT
Power Column
Lower Column to the lowest point. While raising the column, tighten
the hex-key screw in the top of the leadscrew nut. Listen to the
power column motor while tightening the leadscrew nut until you
hear the motor begin to strain. Stop raising the column and back off
the hex-key screw one quarter turn. Your leadscrew nut is now
properly adjusted.
Non-Power Column
For Manual Column Machines, lower the column to the lowest point.
While raising the column using the hand wheel also tighten the
leadscrew nut as described above for the power column. When the
leadscrew nut has been adjusted to the point that significant drag
occurs, back the leadscrew nut hex-key screw one quarter turn.
Note:
Do not attempt to reposition the hex-key wrench while the power column is
moving. Instead, lower the column again then reposition the hex-key wrench and
begin raising and tightening again. After installing a new leadscrew nut you may
need to repeat this process several times until the nut is properly adjusted.
Side-to-Side Column Movement Adjustment
Any side-to-side movement noticed at the grinding head (when
column is locked) can be eliminated by following this procedure.
a) Remove access door at the rear of the machine.
b) Lower column until the rectangular bars are in the most
accessible location.
c) Loosen jam nuts on the bolts located at the ends of both bars
(Figure 35).
d) Adjust bolts out until slight pressure is put on the round
support bars. Tighten jam nuts.
Apply a film of grease on contact area of the support
bars.
