6. Grasp arbor with one hand while loosening
drawbar with the other. Continue to loosen
drawbar until arbor can be withdrawn from
spindle. Wipe out spindle with clean, dry rag.
7. Wipe new arbor with clean, dry rag and push

Head adjustments
See Figure 7-2.
7.2.1
Head elevation
Loosen two handles (R). Turn crank handle (E)
clockwise to raise head on column,
counterclockwise to lower. Always tighten handles
securely before milling or drilling operations.
Figure 7-2: head adjustments
7.2.2
Head swivel
1. To swivel head up to 90° left or 30° right, loosen
lock nut (S) on each side, and remove locating
pin (T).
2. Swivel head to desired angle on scale.
Retighten
both
lock nuts (S).
3. When returning head to vertical position (0-
deg.), re-insert locating pin (T) and securely
tighten both lock nuts (S).
7.3
Table adjustments
See Figure 7-3.
For X-axis longitudinal feed, loosen table locks (L
1
)
and use side handwheel (L
2
). The cross feed table
locks (C
1
) should be kept tight.
For Y-axis cross feed, loosen table locks (C
1
) and
use front handwheel (C
2
). The longitudinal feed
table locks (L
1
) should be kept tight.
The scales can be adjusted by loosening screw (T
1
)
and rotating scale to align with indicator.
The stops (T
2
) can be adjusted to any point along
the longitudinal axis. Retighten screws after
positioning.

Gib adjustments
7.4.1
Table gibs
See Figure 7-3.
Gibs have been properly adjusted by the
manufacturer. After a period of time, however,
movement of the table over the ways will cause
normal wear and some “play” between components.
To adjust gibs to eliminate this play, proceed as
follows.
1. The X-axis gib adjustment screw (XG, Figure 7-
3) is found on right side of saddle beneath table.
The Y-axis gib adjustment screw (YG, Figure 7-
3) is found to the right on the table face.
2. Turn each screw slightly clockwise to tighten.
Turn table handwheels to check tension; slight
drag should be felt during movement.
3. Re-adjust
as
required.
7.4.2
Column gib
A Z-axis gib adjustment screw is located atop the
square column near oil cup (see Z, Figure 7-2).
Follow same principle as described under
sect.
7.4.1
. Slight drag should be felt when turning crank
handle.
7.5
Spindle return
The spindle return is pre-set by the manufacturer
and should not require adjustment. If spring tension
becomes a future issue due to wear, proceed as
follows.
See Figure 7-4.
1.
Loosen knob (A) just enough to rotate spring
cap (B) past pin (C) and settle it on the next
notch.
DO NOT
remove spring cap or allow it
to rotate freely in your hand, or spring may
unwind.
