C. Load Control
(With no work holder in place)
1.
Release the up lock on the right side of the head so that the head is in the
2. down position (do not allow the head to fall to lowest position, but lower it gradually).
3. Turn pressure control knob clockwise(CW) until the center-shaft reaches the bottom stop and thus
becomes heavy.
4. Adjust dial indicator face so that the needle is pointing towards 0.
5. Turn pressure control knob counterclockwise (CCW) until the need lifts off of the stop slightly. This
can be monitored on the dial indicator. When the dial indicator moves, the center-shaft is no longer on
the bottom stop.
6. Now slightly turn pressure control knob CW so that the center-shaft returns to the bottom most
position.
7. Using your hand, lift the center-shaft slightly then lower the center-shaft down to the bottom most
position.
8. Repeat step 6 multiple times to ensure that the center-shaft consistently falls back to the stop (when the
dial indicator needle is at 0).
9. If the center-shaft does not return back to 0, turn pressure control knob slightly CW then repeat step 6
until the center-shaft consistently returns to 0.
10. Complete.
This adjustment can be done every time the pressure control knob has been changed from each sample.
**Note: Turning the pressure control knob CW effectively increase the downward pressure of the center-
shaft and vise versa.
