Loading Tooling
1.DISCONNECT MILL FROM POWER!
2.Clean any debris or surface substances from inside the spindle taper and the mating surface of the tooling.

3.Place the mill in the low spindle speed range to keep the spindle from turning in the next steps.
4.Align the keyway of the tool with the protruding pin inside the spindle taper, then firmly push the tool into the spindle to seat it.
5.With one hand holding the tool in place, insert the drawbar into the spindle from the top of the head, then thread it into the tool (see Figure 44).
