4. 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.
5. When using a collet: Insert the cutter in the
hole at the bottom of the collet and contin-
ue to tighten the drawbar until both the col-
let and cutter are tightly in place. Do not
over-tighten the collet. Grasp the rim of
the front pulley. Hold it tight while tight-
ening the draw bar.
To remove a collet or an arbor:
1. Loosen the hex head at the top of the draw-
bar (2 or 3 turns).
2. Tap on the top of the drawbar with a soft
faced mallet to loosen the collet from the
spindle. Hold the collet/cutter with a
shop towel from the bottom to prevent it
from dropping completely out of the
machine.
3. Continue to turn the drawbar counterclock-
wise until it is free from the collet. Once
loose, remove and replace with your
desired collet. Remove cutting tools from
spindle when not in use.
Your mill comes equipped with a fly cutter that fits
on the 1" stub end of the R-8 arbor (this comes
installed in the spindle).
To install the fly cutter:
1. Clean any accumulated grease, oil, or
debris off of the R-8 arbor.
2. Fit the fly cutter onto the stub end of the
arbor so the keys on the arbor and the key-
ways on the fly cutter come together.
3. Secure the fly cutter to the arbor with the
cap screw and washer provided. Tighten
with an 8mm Allen
®
wrench.
4. Install the arbor with fly cutter into the mill
as described under the heading “Collet or
Arbor Installation.”
The Knee hand crank is located to the left of the

To install properly begin by removing the exter-
nal retaining ring on the end of the shaft. Slide
the handle off of the shaft and re-install so that
the handle faces outward.
