Before beginning the boring operation, take these
precautions:

When ready, use the downfeed handle to lower
the boring head assembly in a controlled manner.
The rate that you move the boring bits into the
workpiece is determined by the workpiece mate-
rial and your experience, and will affect the quality
of the operation.
After the drilling is complete, raise the downfeed
handle so that the boring head assembly is in the
uppermost position, and turn the machine OFF.

Drilling Overview

Make sure the boring head guard is in place
and is free to move up as the boring head
assembly comes down.
Lock the table in the correct position.
Set the depth control to the calculated drilling
depth.
Make sure that your workpiece is firmly
against the longitudinal fence, and use push
sticks to hold it in position.
To avoid personal injury,
always keep hands and
