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).
