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 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.
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 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 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.
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 hands.
Always use a chip hook (*** 6 42 01 001 00 0).
Danger of burning! The surface of the magnet can
reach high temperatures. Do not touch the mag-
net 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 cool-
ing-lubricant system is defective. Each time before oper-
ating, check for tightness against leaks and for cracks in
the hoses. Prevent liquids from entering or penetrating
electrical components.
The magnetic core drill unit is equipped with a overload
protection. When the motor gets too warm, the mag-
netic core drill unit switches off.
PRCD personal protection switch (*)
(see page 11)
The PRCD personal protection switch is specifically
intended for your protection. Do not use the PRCD
personal protection switch for switching the product
on and off.
If the personal protection switch is damaged, e.g. due
to contact with water, do not use it any more.
The PRCD personal protection switch is indispensable;
it is used for protection of the operator against electric
shock. Under fault-free operation, the personal protec-
tion switch control lamp is active.
Check the operability of the PRCD personal protection
switch before beginning to work:
1. Connect the plug of the PRCD personal protection
switch with the mains socket outlet.
2. Press the RESET–button. The personal protection
switch control lamp is active.
3. Disconnect the plug from the mains socket outlet.
The personal protection switch control lamp becomes
inactive.
4. Repeat steps 1. and 2.
5. Press the TEST–button. The personal protection
switch control lamp becomes inactive. In case the con-
trol lamp remains active, do not run the product. In this
case, contact the customer service at www.fein.com.
6. Press the RESET–button. When the control lamp is
active, the product may be switched on.
Do not use the PRCD personal protection switch for
switching the power tool on and off.
