To install a chuck:


If necessary, install an adapter plate before installing the chuck.

  1. Clean the face of the spindle and the back face of the chuck. Position the drive dog at the top of the spindle.
  2. Remove the jaws from the chuck. Remove the center cup or coverplate from the front of the chuck. If available, install a mounting guide into the drawtube and slide the chuck over it.
  3. Orient the chuck so that one of the guide holes are aligned with the drive dog. Use the chuck wrench to thread the chuck onto the drawtube.
  4. Screw the chuck all the way onto the drawtube and back it off 1/4 turn. Align the drive dog with one of the holes in the chuck. Tighten the six (6) SHCS.
  5. Install the center cup or plate with three (3) SHCS.
  6. Install the jaws. If necessary replace the rear cover plate. This is located on the left side of the machine.
