These appliances are not intended for use by persons
(including children) with reduced physical, sensory or
mental capabilities, or lack of experience and knowl-
edge, unless they have been given supervision or
instruction concerning use of the appliance by a person
responsible for their safety.
Children should be supervised to ensure that they do
not play with the appliance.
Safety instructions.
When performing drilling that requires the use of a
fluid, route the fluid away from the operator’s work
area or use a fluid collection device.
Such precaution-
ary measures keep the operator’s work area dry and
reduce the risk of electrical shock.
Operate the power tool by the insulated grasping sur-
faces, when performing an operation where the cutting
accessory may contact hidden wiring or its own cord.
Cutting accessory contacting a “live” wire may make
exposed metal parts of the power tool “live” and could
give the operator an electric shock.
Wear hearing protection when drilling.
Exposure to
noise can cause hearing loss.
When the core bit is jammed, stop applying downward
pressure and turn off the tool.
Check the cause of the
jam and apply corrective action to eliminate the cause
of the jamming application tool.
When restarting a core drill jammed in the workpiece,
check that the core bit rotates freely before starting.
If
the core bit is jammed, it may not start, may overload
the power tool, or may cause the core drill to release
from the workpiece.
When securing the drill stand with a vacuum plate to
the workpiece, install the vacuum plate on a smooth,
clean, non-porous surface. Do not secure to laminated
surfaces such as tiles and composite coating.
If the
workpiece is not smooth, flat or well affixed, the vac-
uum plate may pull away from the workpiece.
Ensure there is sufficient vacuum level before and dur-
ing drilling.
If the vacuum is insufficient, the plate may
release from the workpiece.
Never perform overhead and wall drilling with the
machine secured by the vacuum plate only.
If the vac-
uum is lost, the vacuum plate will release from the
workpiece.
When drilling through walls or ceilings, ensure to pro-
tect persons and the work area on the other side.
The
core bit may extend through the hole or the core may
fall out on the other side.
Do not use this tool for overhead drilling with fluid sup-
ply.
Fluids entering the power tool will increase the risk
of electric shock.
Have the protective cable bushing replaced immedi-
ately when damaged.
A defective protective cable
bushing can lead to overheating of the machine.
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 gener-
ated by the various different operations. Prolonged
exposure to high intensity noise may cause loss of hear-
ing.
Do not touch the sharp edges of the core drill bit.
Dan-
ger 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 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.
Inspect the safety strap each time before using for
damage such as cracks, cuts, nicks and breakage in the
webbing, strong signs of wear and/or corrosion of the
end fittings and tensioning elements, as well as a miss-
ing or unreadable label. Replace the safety strap imme-
diately in case of any defects.
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 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 with materials containing magnesium.
Danger of fire.
Do not work with CFRP (carbon-fiber-reinforced poly-
mer) and materials containing asbestos.
These materi-
als are considered 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.

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 26).
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 the green button on the control panel lights
up permanently, the magnetic holding power may
be sufficient and the machine can be operated with
normal feed
.
– When the
Magnet
button on the control panel
flashes, the magnetic holding power possibly is
insufficient and the machine must be operated with
reduced feed
.
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.
The magnetic foot is monitored by means of a power
sensor. If the magnetic foot is defective, the motor will
not start.
In case of overload, the motor automatically stops and
must be restarted again.
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.
The last set speed is automatically stored (
memory func-
tion
). To start the power tool with the last set speed,
press and hold the button with the symbol, and
then press the button with the symbol.
Do not stop the drill motor during the drilling proce-
dure.
Only remove the core bit from the drilled hole while
the motor is running.
If the core bit should remain stuck in the material, stop
the drill motor and carefully turn the core bit out coun-
ter-clockwise.
Remove the chips and the drilled core after each drilling
process.
Do not touch the chips with your bare hands.
Always use a chip hook (6 42 98 160 40 0).
Danger of burning! The surface of the magnet
can reach high temperatures. Do not touch the
magnet with your bare hands.
When changing a drill bit, pay attention not to damage
the cutting edges.
When core drilling layered material, remove the core
and the chippings after drilling each layer.
When readjusting the drill spindle for tapping, use only
the supplied T-handle spanner or Allen key.
Do not use the magnetic core drill unit when the cool-
ing-lubricant system is defective. Each time
before oper-
ating
, check for tightness against leaks and for cracks in
the hoses. Prevent liquids from entering or penetrating
electrical components.
