The Pilot Pin must be compatible with the cutter. An
improper Pilot Pin may result in an accident. See
Section 5-3 to identify compatible Pilot Pins and
cutters. The proper Pilot Pin to be used will vary,
depending on the type of cutter, the diameter of the
cutter, and the length of the cutter.

The use of an engine-driven welder as a power
source may cause your magnetic driven machine
to malfunction, Power from an engine-driven welder

Do not use an extension cord that is too thin. Do
not use an extension cord that is too long. Do not
use an extension cord that is wound on a drum. Do
not share an extension cord with other motor-driven
tools. These uses can cause voltage to drop and
can reduce the holding power of the magnetic base,
causing the machine to move during operation. This
can decrease performance and may cause damage
to the machine. (Fig.7)

Because the Hi-Broach and Jet-Broach have
rather thin cutting edges with less cutting pressure
resistance as compared to twist drill, do not force to
feed the cutter when drilling manually.
If you feed it with too much force, the cutter may
break or end up with shorter life than otherwise.
