G7945/G7946 Radial Drill Press
-19-
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, carefully follow the instructions
below:
1. Use mineral spirits to thoroughly clean the
drill chuck, arbor, and spindle sockets and
dry all surfaces before assembly.
Failure
to clean the mating surfaces may cause
the tapered fit to loosen during operation,
resulting in separation and an unsafe
condition.
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 drill chuck with a rubber or wooden mallet
to seat it as shown in
Figure 14.
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.

retracted jaws.)
An alternate method is to lay the headstock
and column on the floor, slide them together,
tilt the assembly up, and position the drill
press on its base in the upgright position.
3. Screw two clamp bolts into each side of the
horizontal column bracket ( Figure 12).
