Drill Chuck Removal
The drill chuck and arbor come installed on the
drill press/milling spindle from the factory. When
the time comes to remove and reinstall it, use
these instructions:
To remove the drill chuck from the drill press/
milling spindle:
1. Unplug the lathe/mill!
2.
Return the spindle to the highest position.
3.
Remove the small plastic cap on top of the
belt guard and unscrew the draw bar 3 turns.
Note—The draw bar screws into the arbor
and
keeps the arbor from chattering loose
when machining or drilling. Three turns on
the draw bar is all that you need, any more
and the threads on the draw bar and the
arbor will be damaged when hitting the end
of the draw bar with the hammer. Any less
and the arbor does not have enough room
to pop loose from the inside taper of the
spindle and the outside taper of the arbor.
4. Secure the quill with the quill lock.
5. Holding
onto the outside of the drill chuck
with your free hand (never hold onto any-
thing
from the bottom, when removing it
from the spindle), tap the end of the draw
bar with a soft faced mallet. DO NOT use a
steel hammer! Damage to the draw bar and
hammer, such as chipping, may occur.
6. Once the arbor is loose, hold the drill chuck
with
one hand and unthread the arbor with
the other.
Drill Chuck Mounting
Always disconnect the power to the machine
before making adjustments, set-up changes
or cleaning. Failure to do so could result in
injury to yourself and others.
1. Unplug the lathe/mill!
2.
Remove the small plastic cap on top of the
belt guard and slide the draw bar out of the
spindle through the top.
3. Clean the spindle taper and the arbor taper
thoroughly,
then wipe with your hand until its
clean.
4. Insert the arbor half way into the drill press
spindle,
then quickly slide it in place to seat
the two tapers together.
5. Replace the draw bar and thread it into the
arbor. DO
NOT over tighten! The draw bar
only needs to be lightly tightened. Tightening
any further will make it difficult to remove the
arbor! Again the taper is what holds the two
pieces together, the draw bar just keeps
them from chattering loose.
