Model G0704 (Mfd. Since 05/16)
NOTICE
The Model G0704 drawbar will extract the
arbor from the spindle. Once the arbor or
collet has broken free from the spindle
taper, be sure to properly support it while
continuing to loosen the drawbar. Failure
to properly support the arbor or collet
while loosening the drawbar will result in
the arbor or collet falling out of the spindle,
causing damage to machine components.
To remove the chuck and arbor from the
spindle:
1. DISCONNECT MILL/DRILL FROM POWER!
2. Remove the drawbar cap.
3.
Lock the quill in place with the quill lock
lever.
4. Use the included spindle pin to prevent the
spindle from turning while you use an 8mm
wrench to loosen the drawbar 2–3 turns. DO
NOT continue loosening the drawbar without
supporting the drill chuck or it will fall from the
spindle.
5. Hold the chuck with one hand and finish loos-
ening the drawbar until the chuck falls out of
the spindle.
Note: The chuck is attached to the arbor
using a B-16 taper. This attachment is con-
sidered to be semi-permanent. There should
be no need to remove the chuck from the
arbor.
