Drill Chuck and Arbor
The drill chuck attaches to the drill spindle by means of a
drill chuck arbor. Matched tapers on the arbor and chuck
bore create solid assembly when properly joined.
To assemble the drill chuck and mount it to the spindle,
carefully follow the instructions below:
IMPORTANT: 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.
1. Use the provided chuck key to adjust the jaws of the
chuck until they are well inside the drill chuck body.
2. Place the drill chuck on a workbench jaw side down.
3. 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. If the
chuck fails to remain secure on the arbor repeat the
previous steps to clean the surfaces.
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 upward on the end of the drill chuck
with a rubber or wooden mallet to seat
the arbor assembly.
