Drill Chuck Removal
The Model G0463 may have shipped with the drill
chuck installed in the spindle. If this is the case,
go ahead and remove the chuck and arbor at this
time.
Tools Needed: Qty
Brass Hammer .................................................. 1
Pin Spanner ....................................................... 1
Wrench 17/19mm .............................................. 1
To remove the chuck and arbor from the
spindle:
1. UNPLUG THE MILL/DRILL!
2. Remove the safety cap that covers the
drawbar.
3. Lock the quill in place with the quill lock.
4. Insert the pin spanner into the two holes at
the bottom of the spindle. This will keep the
spindle from turning, and allow you to loosen
the drawbar (see
Figure 8).
NOTICE
DO NOT completely unscrew the drawbar
before striking it with the hammer. You will
damage the threads on the drawbar and the
arbor.
6. Tap the top of the drawbar with the hammer.
This will unseat the taper of the arbor and the
spindle (see
Figure 9).
7. Hold one hand under the chuck and finish
loosening the drawbar by hand until it falls out
of the spindle.
Note: The chuck is attached to the arbor
using a JT6 taper. This attachment is consid-
ered to be semi-permanent. There should be
no need to remove the chuck from the arbor.
Inspect the chuck from time to time to make
sure it is still tight on the arbor. If it is loose,
use an dead-blow or other soft headed ham-
mer to re-seat the taper.
5. Using the 17mm wrench, loosen the drawbar
but DO NOT remove it.
