Special safety instructions.
Wear personal protective equipment. Depending on the
application, use a face shield, safety goggles or safety
glasses. Wear ear protection. The safety glasses must be
capable of protecting against flying particles generated
by the various different operations. Prolonged expo-
sure to high intensity noise may cause loss of hearing.
Do not touch the sharp edges of the core drill bit. Danger
of injury.
To avoid injuries, check the core drill bits prior to start-
ing the work. Use only undamaged core drill bits that
are not deformed. Damaged or deformed core drill bits
can cause serious injury.
Before putting into operation: Mount the contact protec-
tor to the machine.
Always secure the power tool with with the provided
safety strap. When carrying out such work, beware of
falling objects, such as core bits or chips.
When working overhead or on vertical surfaces, the
coolant container must not be used. Use a coolant spray
instead. Liquids penetrating your electric power tool
may cause electric shock.
Avoid touching the drilled core that is automatically
ejected by the centering pin when the working proce-
dure is finished. Contact with the core when it is hot, or
if it falls, can cause personal injuries.
Operate the power tool only from grounded sockets that
comply with the specifications. Do not use any connec-
tion cables that are damaged; use extension cables with
a grounding contact that are checked at regular inter-
vals. A ground conductor without continuity can cause
an electric shock.
To prevent injuries, always keep your hands, clothing,
etc. away from rotating swarf. The swarf can cause inju-
ries. Always use the chip guard.
Do not attempt to remove the cutting tool if it still turns.
This can lead to serious injuries.
Beware of any concealed electric cables, gas or water
conduits. Check the working area before commencing
work, e. g. with a metal detector.
Do not work materials containing magnesium. Danger
of fire.
Do not work CFP (carbon-fiber-reinforced polymer) and
materials containing asbestos. These materials are con-
sidered carcinogenic.
Do not rivet or screw any name-plates or signs onto the
power tool. If the insulation is damaged, protection
against an electric shock will be ineffective. Adhesive
labels are recommended.
Do not overload the power tool or the storage case and
do not use it as a ladder or stand. Overloading or stand-
ing on the power tool or the storage case can lead to the
upward shifting of the centre of gravity of the power
tool or the storage case, and its tipping over.
Do not use accessories which are not specifically
designed and recommended by the power tool manufac-
turer. Safe operation is not ensured merely because an
accessory fits your power tool.
Clean the ventilation openings on the power tool at reg-
ular intervals using non-metal tools. The blower of the
motor draws dust into the housing. An excessive accu-
mulation of metallic dust can cause an electrical hazard.
For transport of the machine, use only swivel eyelets.
After assembling, check the tight seating of the eyelet.
Before putting into operation, check the mains connec-
tion and the mains plug for damage.
Always operate the power tool with the supplied RCD
safety switch. Before beginning to work, always check
the proper functioning of the RCD safety switch (see
page 33).
Hand/arm vibrations
The vibration emission level given in this information
sheet has been measured in accordance with a standard-
ised test given in EN 62841 and may be used to com-
pare one tool with another. It may be used for a
preliminary assessment of exposure.
The declared vibration emission level represents the
main applications of the tool. However, if the tool is
used for different applications, with different accesso-
ries or poorly maintained, the vibration emission may
differ. This may significantly increase the exposure level
over the total working period.
An estimation of the level of exposure to vibration
should also take into account the times when the tool is
switched off or when it is running but not actually doing
the job. This may significantly reduce the exposure level
over the total working period.
Identify additional safety measures to protect the oper-
ator from the effects of vibration such as: maintain the
tool and the accessories, keep the hands warm, organi-
sation of work patterns.
Operating Instructions.
Only use water-soluble cutting fluids (oil in water) as
the cooling agent.
Observe the manufacturer's instructions on coolant.
Pay attention that the set-up surface for the magnetic
foot is flat, clean, rust-free and ice-free. Remove varnish,
putty/filler layers and other materials. Prevent an air gap
between the magnetic foot and the set-up surface. The
air gap reduces the magnetic holding power.
Do not operate this machine on hot surfaces; it could
lead to a permanent reduction of the magnetic holding
power.
When working, always use the magnetic foot; pay
attention that the magnetic holding power is sufficient:
– When the green signal lamp lights up permanently,
the magnetic holding power possibly is sufficient and
the machine can be operated with normal feed.
– When the green signal lamp flashes, the magnetic
holding power possibly is insufficient and the
machine must be operated with reduced feed.
When working on steel materials with a material thick-
ness of less than 12 mm, the workpiece must be rein-
forced with an additional steel plate in order to
guarantee the magnetic holding power.
In case of overload, the motor automatically stops and
must be restarted again.
