Avoid touching the drilled core that is automatically
ejected by the centering pin when the working procedure
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 connection
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.
Hold power tool by the insulated gripping surfaces, when
performing an operation where the cutting accessory
may contact hidden wiring or its own cord. Cutting acces-
sory contacting a "live" wire may make exposed metal
parts of the power tool "live" and could give the opera-
tor an electric shock.
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 standing
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 regu-
lar 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 putting into operation, check the mains connec-
tion and the mains plug for damage.
Recommendation: The tool should always be supplied
with power via a residual current device (RCD) with a
rated current of 30 mA or less.
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 60745 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 accessories 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 opera-
tor from the effects of vibration such as: maintain the tool
and the accessories, keep the hands warm, organisation
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.
Pay attention that the magnetic holding power is suffi-
cient.
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 instructions 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.
If the magnet is not positioned on a magnetisable plate or
when the magnetic foot is defective, the motor will not
start.
Work only with the absolutely required amount of feed.
Excessive feed can lead to breakage of the application
tool and loss of the magnetic holding power.
When the power supply is disconnected while the motor
is running, a protective circuit prevents automatic restart-
ing of the motor. Restart the motor again.
Do not stop the drill motor during the drilling procedure.
Only remove the core bit from of the drilling 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 hand.
Always use a chip hook.
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.
