The arbor can be removed to install another drill
chuck in the spindle. A drift key is included to help
remove the arbor from the spindle. Usually, once
the chuck and arbor have been properly mounted
together, they are considered semi-permanent
connections. (If you would like to install a differ-
ent chuck, we recommend getting a new arbor for
that chuck.)
To remove the drill chuck and arbor:
1. UNPLUG THE DRILL PRESS!
2. Rotate the spindle handles until the drift-key
slot is exposed in the side of the quill.
3. Loosen the lock knob and rotate the hub
(Figure 31) clockwise until it stops.

7. Insert the drift key into the drift-key slot.
8. Tap the drift key with a rubber or wooden
mallet, as shown in Figure 33, until the
chuck releases.
4. Tighten the lock knob. The quill should not
return up into the head casting.
5. Move the table up until it is
1
⁄4" below the bot-
tom of the chuck, and place a towel or cloth
under the chuck.
6. Rotate the spindle until the inner drift-key slot
is aligned with the outer slot, as shown in
Figure 32. You will see through the spindle
when the slot is properly aligned.
