For your safety.
Read all safety warnings and all
WARNING
instructions. Failure to follow the
warnings and instructions may result in electric shock,
fire and/or serious injury.
Save all warnings and instructions for future reference.
Do not use this power tool before you have
thoroughly read and completely understood this
Instruction Manual and the enclosed "General
Safety Instructions" (document number
3 41 30 465 06 0). The documents mentioned should
be kept for later use and enclosed with the power tool,
should it be passed on or sold.
Please also observe the relevant national industrial
safety regulations.
Intended use of the power tool:
Magnetic core drill unit for drilling with core drill bits
and solid drill bits on materials with surfaces suitable for
magnets in weather-protected environments using the
application tools and accessories recommended by
FEIN.
In environments subject to interference, a reduction of
the operating quality is possible; this can include tem-
porary failure, temporary reduction of the function or
the intended operating behaviour, for the correction of
which intervention by the operator is required.
This power tool is also suitable for use with AC gener-
ators with sufficient power output that correspond to
the Standard ISO 8528, design type G2. This Standard
is particularly not complied with when the so-called dis-
tortion factor exceeds 10 %. When in doubt, please
refer to the generator instruction/specification guide.
Observe the operating instructions and the national
regulations for the installation and operation of the AC
generator.
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 gripping sur-
faces when performing operations where the cutting
accessory could contact hidden wiring or its own power
supply cable. Contact of a cutting accessory with 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.
