The drill chuck attaches to the drill spindle by means of a drill chuck arbor. Matched tapers
on the arbor and back of the chuck create an almost permanent assembly when properly
joined.
Figure8 To assemble the drill chuck and mount it to the spindle, carefully follow
the instructions below:
1. The drill chuck, arbor and spindle socket must be thoroughly cleaned and dried before
assembly. It is recommended that mineral spirits be used for this task. Refer to the
safety warnings on the container of the mineral spirits.
Failure to clean the mating
surfaces may result in separation and an unsafe condition . Separation is usually
caused by oil or grease on the taper.
2. Use the provided chuck key to adjust the jaws of the chuck until they are well inside the
drill chuck body.
3. Place the drill chuck on a workbench face down. The arbor has a short taper and a long
taper. Place the short taper into the socket in the back of the drill chuck and tap with a
rubber or wooden mallet as shown in
Figure 9 . If the chuck fails to remain secure on
the arbor, repeat step 1 and 2 .
4. Slide the arbor into the spindle socket while slowly rotating drill chuck. The socket has
a rectangular pocket in which the tang (or flat portion of the arbor) fits into. Once the
tang is oriented correctly the drill chuck will not rotate without turning the spindle.
5. Tap the end of the drill chuck with a rubber or wooden mallet to seat it as shown in
Figure 10 .

Arbor Removal
A drift key is included to aid in the drill chuck arbor removal.
1. Rotate the spindle handles until the slot is exposed in the side of the quill.
2. Rotate the spindle until the inner slot is aligned with the outer as shown in Figure 11 .
You will see through the spindle when the slot is properly aligned.
3. Insert the drift key into the slot and allow the quill to rise, trapping the drift key. Hold the
drill chuck with one hand and tap on the drift key with a hammer as shown in Figure 12 .
