・
Clean the adhesion surface of the Magnet and the
surface of the workpiece. Any gaps between the
adhesion surface of the Magnet and the surface of
the workpiece will weaken the adhesive power of the
Magnet and may cause the tool to swing around.
Therefore the surfaces should always be kept clean
and free from metal chips, bumps and depressions or
rust. Also, do not place the Magnet over holes as this
will also weaken the adhesion.
・
Use the Chain to prevent the tool from falling. Use
the attached Chain to attach the tool to the workpiece
where there is a risk that it might fall from a high place
or tip over if the Magnet lifts off during a power
stoppage or for some other reason. Use Supporting
Magnet Assy (option) to prevent main body of unit
from falling when the chain can not be wound around
work because its size is too large to wind.

・
Align the Magnet parallel to the length of the
workpiece. Since the surface of an H-section is
normally curved as shown in Figure 6, the Magnet
should be placed parallel to the length of the workpiece
to ensure good adhesion and safe working. Insecure
magnetic adhesion is the cause of cutter damage and
unexpected accidents. (Fig. 6, Fig. 7)

・
When performing maintenance, inspection,
replacement or adjustment of parts, make sure to
disconnect the plug from the receptacle.
・
Do not operate on the ceiling. The tool should be
operated on a horizontal place or the wall (vertically).
Do not operate the tool on the ceiling (upside down) .
(Fig. 2) Never use this unit at the work on ceiling
(upside down). Remove oil supply portion from main
body and mount unit so that the cutting oil will not be
spilled off when the unit is used on wall (vertically).

・
Minimum workpiece thickness of 9mm. If a
workpiece is not thick enough, it will weaken the
magnetism, preventing proper operation due to the
slipping or lifting from the workpiece. When drilling a
workpiece of insufficient thickness, it is recommended
that a piece of iron, approximately 10mm thick and
somewhat larger in size than that of the Magnet, be
placed on the reverse side of the workpiece.
