5. Move the carriage again and readjust if
necessary.
Note: Over-adjustment will cause excessive
and premature wear of the gibs.
12.2 Cross slide
If the cross slide is too loose, follow procedure
below to tighten:
1. Loosen the rear gib screw (not shown)
approximately one turn.
2. Tighten the front gib screw (B, Fig. 23) a
quarter turn. Turn the cross slide handwheel to
see if the cross slide is still loose. If it is still
loose, tighten the front screw a bit more and
try again.
3. When the cross slide is properly adjusted,
tighten the rear gib screw.
Note: Over-adjustment will cause excessive
and premature wear of the gibs.
12.3 Compound rest
Follow the same procedure as the cross slide
adjustment to adjust the compound rest. Rear gib
screw is shown (A, Fig. 23). Front gib screw (not
shown) is by the handwheel.

If the handle (A, Fig. 24) will not lock the tailstock,
follow the procedure below :
1. Lower the handle to the unlocked position.
2. Slide the tailstock to an area that allows
access to the underside of the tailstock.
3. Tighten tailstock clamping bolt (underside of
tailstock) 1/4 turn. Test for proper locking.
Repeat as necessary.
12.5 Tailstock off-set
Follow the procedure below to off-set the tailstock
to cut shallow tapers:
1. Lock tailstock in position by raising locking
handle (A, Fig. 24).
2. Alternately loosen and tighten two hex socket
cap screws (B, Fig. 24).
12.6 Tailstock gibs
Take up play in the tailstock by tightening two gib
screws (C, Fig. 24) on either side of the tailstock
base.
