1. To adjust drag, loosen rear gib screw one turn,
and tighten front gib screw a quarter turn.
Rotate handwheel to check play. If still loose,
tighten front gib screw a bit more.
2. Repeat as needed until slide moves freely
without play.
3. When cross slide is properly adjusted, snug
rear gib screw. Do not overtighten; this will
cause premature wear on gib and mating parts.

11.2.3 Cross slide nut adjustment
The cross slide moves via a lead screw which drives
a nut. This can also be adjusted if backlash
develops. Turn cross slide handwheel left and right;
if there is a delay before any cross slide movement,
the nut needs adjusting. Tighten or loosen screw (D,
Figure 11-3) and move cross slide to verify setting.
11.2.4 Top slide gib adjustment
Gib screws are located at front and rear of top slide
(E, Figure 11-3). To adjust, use same method as for
cross slide gib above.
11.3 Tailstock adjustments
The tailstock can be offset to cut shallow tapers up
to 5° angle. See Figure 1-4.
1. Release clamping lever (F).
2. Alternately loosen and tighten front and rear
screws (G) to move tailstock laterally across
base. The scale (H) on end of tailstock indicates
amount of offset, and helps when re-centering.
3. Tighten clamp lever (F).
If the clamping force needs to be adjusted, remove
tailstock from bed and turn it over. Adjust the hex
nut as needed.

11.4 Gap section
To remove gap section (Figure 11-5):
1. Remove four socket head bolts (J) with hex
wrench.
2. Remove two tapered alignment pins (K) by
threading an M6 screw down into it, until the pin
is loosened enough to be pulled out.
3. Remove gap section.
Figure 11-5
To reinstall gap section:
1. Thoroughly clean bottom and ends of gap
section.
2. Set gap section in place and align the ends.
3. Insert tapered pins (L) into their holes through
gap and into lathe bed.
4. Re-insert the six bolts (A,B) and tighten
alternately until all are snug. Make sure gap
remains aligned with ways while tightening
screws.
