The arbor can be removed to install other Morse
Taper tooling in the spindle. A drift key is included
to help remove the arbor or other tooling 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 different chuck, we
recommend getting a new arbor for that chuck.)
To remove the drill chuck and arbor:
1. DISCONNECT MACHINE FROM POWER!
2. Rotate the spindle handles until the drift-key
slot is exposed in the side of the quill.
3.
Rotate the depth stop hub clockwise until it
stops.
4.
Tighten the lock knob. The quill should not
return up into the head casting when the
depth stop is adjusted this way.
5. Rotate the spindle until the inner drift-key slot
is aligned with the outer slot, as shown in
Figure 35. You will see through the spindle
when the slot is properly aligned.
7. Hold the drill chuck with one hand, and tap
on the drift key with a rubber or wooden
mallet, as shown in Figure 36, until the chuck
releases.
Removing Arbor
6. Insert the drift key into the drift-key slot, and
allow the quill to rise, trapping the drift key.
8.
Hold a downfeed handle with one hand, and
loosen the depth stop lock with the other
hand.
9.
Carefully retract the quill into the head stock.
