The drill chuck is attached to the drill spindle by
means of a machined taper between the chuck
and spindle nose. An almost permanent assem-
bly is created when properly joined. To assemble
the drill chuck and mount it to the spindle, care-
fully follow the instructions below:
1. The drill chuck and spindle must be thor-
oughly 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 a result of oil or
grease on the taper.
2. Use the chuck key provided to adjust the
jaws of the chuck until they are well inside
the drill chuck body.
3. Slide the chuck onto the spindle end and tap
the end of the drill chuck with a rubber or
wooden mallet to seat it. See
Figure 9.
Drill Chuck and Arbor
DO NOT use a steel hammer on the drill
chuck to seat it onto the spindle. Damage
will occur to the chuck and/or spindle
which may make them unusable or unsafe.
