ADJUSTMENTS
7. Engage the next available spring-cover lock
slot with the locking lug, and hold the
spring lock cover tightly against the side of
the headstock (see Figure 27).
8. Snug the cover nut against the spring cover
just until the nut stops, and then back-off
the nut approximately
1
⁄3 turn, or just
enough so there is no binding anywhere
along complete spindle travel.
9. Hold the cover nut and tighten the jam nut
against the cover nut (see Figure 27).
While you may never have to adjust the quill
shaft screw, you should understand its function
and know how to adjust it should you ever need
to remove the quill for cleaning. This screw pre-
vents the quill from rotating during drilling and
sanding procedures, and if adjusted incorrectly,
the quill may have lash or bind.
To adjust the quill-shaft screw, do these steps:
1. UNPLUG THE DRILL PRESS!
2. Clean and lubricate the quill shaft with a
thin coat of light oil, and make sure the quill
travels freely (see Figure 28).
3. Loosen the jam nut shown in Figure 29.
4. Turn the quil shaft screw clockwise or coun-
terclockwise to establish free, unbinding
travel while moving the quill up and down
through its entire range of travel.
5. When the quil shaft screw is screwed inward
against the quill as far as the screw can go
without binding the quill, hold the screw and
tighten the jam nut.
6. Recheck for quill binding and looseness
while moving the quill up and down through
its entire range of travel and readjust as
required.
UNPLUG your machine dur-
ing all assembly, adjust-
ments, and maintenance
procedures. Otherwise
serious personal injury
may occur!
