Align the magnet parallel to the longer direction of
the work piece.
●
Since the surfaces of both sides of H-beam is
normally warped as shown in Fig. 4, the magnet
should be placed parallel to the longer direction of
the work piece to ensure good adhesion and safe
job. Insecure magnetic adhesion is the cause of
cutter damage and unexpected accidents.

Be careful about chips.
●
Keep your hands away from the cutting area at all
times. During drilling, there will be chips. The chips
are sharp. The chips are rotating with the cutter. Any
contact with the chips can cause severe injuries.
Do not touch the slug.
●
Do not touch the slug. The slug is very hot. It will
cause severe burns. Make sure that no one touches
the slug. Make sure that there is no one below the
work area during operation. Hot slugs will fall. Hot
slugs can cause severe burns, other severe injuries,
or even death. Always wear protective equipment,
including protective headgear, eye protection,
hearing protection, and gloves. Do not allow any
person without protective equipment to come near
the machine.
Do not use your hands to remove chips.
●
Chips have sharp edges. Use a screwdriver to
remove chips. If you use your hands to remove
chips, you can be injured, even if you are wearing
gloves. Do not use your hands to remove chips
under any circumstances.
The cutting edge is sharp.
●
Always wear gloves when changing the cutter. The
cutting edge is sharp. If you do not wear gloves,
you will be cut. Attempting to change the cutter can
result in severe injuries.
Do not use Cutting Oil for other purposes.
●
Cutting Oil should be used only for drilling. Please
refer to Section 5-6 of this manual for further
warnings and instructions about Cutting Oil.
CAUTION
Always use a compatible Pilot Pin.
●
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.
Do not use power that is generated by an engine-
driven welder.
●
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
can damage the electronic circuits in your portable
drilling machine.
Use a Proper extension cord.
●
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. 6)
