5.
Using the 17mm wrench, loosen the drawbar
one turn only. DO NOT remove it.
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 from
the spindle (see Figure 13).
Figure 13. Tapping on the drawbar.
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 a dead-blow or other soft headed ham-
mer to re-seat the taper.

R-8 Collets
If you do not use the drill chuck and arbor, you
need to use a collet to insert the cutting tool into
the spindle. Your Model G0619 features an R-8
spindle taper, which gives the freedom to use
standard R-8 collets. These optional collets come
in many sizes, typically ranging from
and 3mm to 20mm, and should be matched to
your cutting tool shank size.
To install the R-8 collet:
1.
DISCONNECT THE MILL/DRILL FROM
POWER!
2.
Unscrew the drawbar cap.
3.
Carefully clean the surface of the collet and
spindle taper. Ensure that it is free of debris
and is lightly oiled.
4.
Insert the cutting tool into the collet, then
insert the collet up into the spindle taper.
5.
Rotate the collet so it engages the align-
ment pin inside of the spindle, then slide the
collet upward until it makes contact with the
drawbar threads.
6.
Thread the drawbar into the collet until the
collet draws up into the spindle taper.
7.
While supporting the tool in the collet with
one hand, snug the drawbar with the drawbar
hex wrench in your opposite hand.
Note: Do not overtighten the drawbar.
Overtightening makes collet removal difficult
and will damage the drawbar threads, collet,
and the spindle taper. Keep in mind that the
taper keeps the collet and tool in place. The
drawbar simply aids in seating the taper.
