Installing Drill Chuck
A JT#6 (Jacobs Taper #6) keyed chuck is included
with the Model G9749 drill press
.
To install the drill chuck onto the arbor:
1. UNPLUG THE DRILL PRESS!
Note: The arbor and spindle come from the
factory pre-installed into the quill. To replace
the arbor or spindle, refer to the
Removing/
Installing Arbor and Chuck
section on
Page 23.
2. Prepare the mating surfaces of the arbor and
the chuck by cleaning them thoroughly.
3. Retract the chuck jaws all the way inside the
chuck.
4. Push the chuck onto the arbor, and using a
wood block and hammer or mallet as shown
in Figure 13, hit the chuck ONCE with mod-
erate force to secure it on the arbor.
Note: Hitting the chuck directly with a steel
hammer or with excess force may damage
the chuck, making it unsafe to use.
