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.
●
Provide fall prevention using lashing belt. (Fig. 4).
Attach the lashing belt attached to the belt attachment
plate of the machine and fix the work piece to prevent
drop or fall of the machine due to working in high
places or wall surface or because of lifting of magnet
by low voltage of the battery pack, etc. Use the
Supporting Magnet Ass’y (optional) for fall prevention
of the machine when the lashing belt cannot be
wrapped around the work piece due to its large size.
Properly fix the lashing belt using the buckle to
prevent loosening of the belt lashing.

●
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. 5)

●
Do not touch the rotating cutter or swarf with
your hands, body, gloves, hair or clothes.
●
Beware of slag being ejected when a hole
is finished.
Wear protective gear since slag
(metal chips) is ejected with great force when a
hole is finished. Do not allow unprotected people
to approach the work site. When working in high
places, make sure there is no one underneath and
be very careful of falling slag. The slag is hot, do
not touch it with bare hands.
●
When clearing away metal chips, set the Magnet
Switch to Off.
Do not touch the chips with your
hands, use a rod such as a screwdriver to remove
them.
●
When replacing cutters, do not touch the cutting
blades with bare hands.
●
You must use a Pilot Pin which matches the cutter.
Pilot Pins differ according to cutter type, diameter
and length (depth). An accident may be caused if
the cutter and Pilot Pin combination is wrong.
Refer to item 6-3 cutter and Pilot Pin Combinations.
●
Do not use Cutting Oil for other purposes.
Refer to item 6-7 Preparing the Cutting Oil.
●
Do not remove labels or name plates from the tool.
Contact the sales agent from whom you purchased
the tool or an authorized dealer if a label or name
plate is damaged or missing.
●
When you put the machine back to the carrying
case, please make sure to let out the cutting oil
from Oil Tank.
CAUTION
●
Non-magnetic (aluminum, stainless steel, copper
alloy, etc.) workpiece can not be used since the
Magnet will have no adhesion to it.
●
Do not apply excess force on feed during manual
drilling.
HI-BROACH and JETBROACH have thin
cutter blades with lower cutting resistance than twist
drills. Therefore they should not be fed forcibly manual
drilling. Be careful because if more than necessary
force is used the cutters will be damaged and their
useful life will be shortened.
●
Never touch the drill after attaching the battery
pack to the machine.
●
Make sure that nobody is underneath the work
area when working in high places.
●
Securely attach the battery pack.
