9. Feed Direction Knob (M, Figure 9-2): Push in
for left-to-right motion; pull out for right-to-left
motion.
10. Half Nut Lever (N, Figure 9-2): Engages
leadscrew for threading operations – down to
engage, up to disengage.
11. Spindle Direction Control Lever (O, Figure 9-
2). Move lever to the right so that its tab clears
the notch, then down for forward spindle
rotation, or up for reverse spindle rotation. Allow
spindle to come to a stop before changing
directions
.
Position lever in neutral position (tab
in notch) before shutting off lathe.
12. Power Feed Engagement Lever (P, Figure 9-
2): Engages powered operation. Push to one of
three positions: LEFT and UP for cross feed
operation (cross slide powered movement);
RIGHT and DOWN for longitudinal operation
(carriage powered movement); MIDDLE
position allows engagement of half nut for
threading.
13. Threading Dial (R, Figure 9-2): Indicates point
on leadscrew where half nut can be re-engaged
to continue inch threading.
14. Cross Slide Handwheel (S, Figure 9-2):

as needed.
15. Top Slide: Located atop cross slide (T, Figure
9-2); can be rotated 360° after loosening two
socket head screws (T
1
) in the circular base.
Calibrations in degrees at the base will assist
angle placement. Tighten screws (T
