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 pro-
tector to the machine.
Always secure the machine with the supplied
safety strap. Especially on inclined or uneven
surfaces there is risk of unsecured machines tip-
ping over.
When working overhead, beware of falling objects,
such as cores 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
intervals. 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 swarf protector.
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 manu-
facturer. 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.
Before storage: Remove the application tool.
Store the power tool only in the case or packaging.
Before putting into operation, check the mains connec-
tion and the mains plug for damage.
Always operate the power tool with together with a
PRCD personal protection switch (*).
Before beginning to work, always check the proper
functioning of the PRCD personal protection switch (*)
(see page 24).
Hand/arm vibrations
The vibration emission level given in this information
sheet has been measured in accordance with a stand-
ardised test given in EN 62841 and may be used to
compare 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 expo-
sure 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 var-
nish, putty/filler layers and other materials. Prevent an
air gap between the magnetic foot and the set-up sur-
face. 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 working non-magnetic materials, suitable FEIN
fastening devices, such as vacuum plates or pipe drilling
devices, which are available as accessories, must be
used. Observe the corresponding operating instruc-
tions for these.
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.
Work only with the absolutely required amount of
feed. Excessive feed can lead to breakage of the appli-
cation tool and loss of the magnetic holding power.
When the power supply is disconnected while the
motor is running, a protective circuit prevents auto-
matic restarting of the motor. Restart the motor again.
Do not stop the drill motor during the drilling proce-
dure.
