Feed Levers
The feed levers control the up and down move-
ment of the spindle
To mount the feed levers to the machine:
1. Screw a black knob onto an end of each of
the three chrome feed levers.
2. Screw the levers with knobs into the threaded
holes on the hub, located on the right side of
the machine (Figure 21).
Collet/Arbor
The Model G1006/G1007 feature an R-8 spindle
which accepts many industrial collets and arbors.
To install a collet or an arbor:
1. Release the latches on the head cover and
open it.
2. Insert the collet or cutting tool’s arbor up into
the spindle housing. Rotate the collet or arbor
to line up the keyway with the matching pin in
the spindle opening (Figure 22).
Figure 22. Collet arbor installation.
3. Turn the hex head at the top of the drawbar
(located on the top, front of the head) clock-
wise until the threads at the bottom of the
drawbar mesh with the female threads in the
top of the collet or arbor.
4. Insert the cutter in the hole at the bottom of
the collet and continue to tighten the drawbar
until both the collet and cutter are tightly in
place. Do not over-tighten the collet. Grasp
the V-Belt that goes around the front pulley.
Pull gently while tightening.
