Removing Tools
To install a tool in the spindle, do these steps:
1. DISCONNECT THE LATHE/MILL FROM POWER!
2. Carefully clean the surface of the arbor and spindle
taper. Ensure that they are free of debris and burrs
.
3. Insert the arbor into the spindle, and rotate the
arbor so the slot in the arbor lines up with the pin
inside of the spindle.
4. Press the arbor up firmly to seat it with the spindle.
5. Finger tighten the drawbar into place (Figure 45),
then use a 12mm wrench to tighten the drawbar
(Figure 46).
Note: Overtightening the drawbar makes removal
difficult and stretches the threads of the arbor and
the drawbar.
6. Clear away all items from the cutting tool before
turning the mill
ON.
