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 possi-
bly is 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.

Meaning
Magnetic holding power possibly
sufficient.
Magnetic holding power insufficient. Even when working on steel materials
– Motion sensor has actuated
– Overload shut-off has actuated
– Hand lever not set to 100 %
position
– Buttons for left rotation/right
rotation blocked
– Check battery indication
Power tool is defective.
Even when working on steel materials where the mate-
rial thickness is below 9 mm, the work piece must be
made thicker with an additional steel plate in order to
ensure the magnetic holding power.
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
then press the button with the
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 hand.
Always use a chip hook.
Danger of burning!
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 cool-
ing-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 electrical components.
Corrective Action
where the material thickness is below
9 mm, the work piece must be made thicker
with an additional steel plate in order to
ensure the magnetic holding power.
After malfunction correction, the power
tool can be switched on again.
Send the machine to your FEIN customer
service agent.
