Removing/Installing
Arbor and Chuck
Use the drawbar included with the Model G9749
to connect the included drill chuck arbor.
To remove the arbor and chuck from the
spindle:
1. UNPLUG THE DRILL PRESS!
2. Use a 3mm hex wrench to remove the belt
housing cover (see Figure 21).
3. Raise the quill to the highest position, and
hold it place by tightening the quill lock
lever.
4. Use a 17mm wrench to unscrew the drawbar
2–3 full turns without removing the threads
from the arbor (see
Figure 22).
5. Using a brass hammer or rubber mallet, strike
the drawbar from the top, as shown in Figure
22, with a firm blow until the arbor releases
from the spindle.
6. While holding the arbor and chuck with one
hand, unthread the drawbar completely from
the arbor.

DO NOT operate the drill press when the belt

entangle hands or clothes causing serious
personal injury.
