Installing Cutters; Removing Cutters - Grizzly G0492 Owner's Manual

Installing Cutters

To install a cutter in the spindle:
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
44), then use a 12mm wrench to tighten the
drawbar (Figure 45).
Note: Overtightening the drawbar makes
removal difficult and stretches the threads of
the arbor and the drawbar.
