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.
When working, always use the magnetic foot; pay atten-
tion that the magnetic holding power is sufficient:
– When the green button on the control panel lights up
permanently, the magnetic holding power is sufficient
and the machine can be operated with manual or
automatic feed.
– When the Magnet button on the control panel
flashes, the magnetic holding power possibly is insuf-
ficient 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 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.
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 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.
Adjust the gear setting only when the machine is at a
complete stop or when the motor is running down.
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
press the button with the
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.
Do not use the magnetic core drill unit when the cooling-
lubricant system is defective. Each time before operating,
check for tightness against leaks and for cracks in the
hoses. Prevent liquids from entering or penetrating elec-
trical components.
