However, if the power tool is used for other applica-
tions, with deviating application tools or insufficient
maintenance, the overall vibration values and the noise
emission values may differ. This can significantly
increase the vibration and noise exposure over the total
working period.
For an accurate estimation of vibration and noise expo-
sure, the durations when the equipment is switched off
or running but not actually in use should also be taken
into account. This may significantly reduce the vibration
and noise exposure over the total working period.
Identify additional safety measures to protect the
operator from the effects of vibration and noise
such as: Maintain the power tool and the accesso-
ries, keep the hands warm, organization 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.
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

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.
