Tools Needed
Wrench 19mm ................................................... 1
Brass Hammer .................................................. 1
To load tooling:
1.
DISCONNECT MACHINE FROM POWER!
2.
Clean any debris or surface substances from
inside spindle taper and mating surface of
tooling.
Note: Debris or oily substances can prevent
tooling and spindle from properly mating.
This condition can cause excessive vibration,
poor cutting results, or tool/workpiece dam-
age.
3.
Align tooling keyway with pin inside spindle
taper, then firmly push tooling into spindle to
seat it.
Cutting tools are sharp and can easily
cause laceration injuries. Use heavy leather
gloves or shop rags to protect your hands
when handling cutting tools.

4.
With one hand holding the tooling in place,
insert vertical drawbar (longer of two draw-
bars) into spindle from the top of the head,
then thread it into tooling (see Figure 21).
Note: The drawbar has an adjustment hex
nut under the head that is used to raise/lower
the drawbar to compensate for different tool-
ing lengths.

5.
Tighten drawbar until it is snug. Avoid over-
tightening, as this could make removing tool-
ing difficult later.
To unload tooling:
1.
DISCONNECT MACHINE FROM POWER!
Note: Make sure drawbar has at least three
threads engaged with tooling in the next step
to avoid damaging drawbar threads or tool.
2.
Loosen drawbar a couple of turns, then tap
the top of it with a brass hammer to knock
taper between the spindle and tooling loose.
3.
Support tooling with one hand, then com-
pletely unthread drawbar from tooling.
