Special safety instructions.
Wear personal protective equipment. Depending on the
application, use a face shield, safety goggles or safety
glasses. Wear ear protection. The safety glasses must be
capable of protecting against flying particles generated by
the various different operations. Prolonged exposure to
high intensity noise may cause loss of hearing.
Replace the protective cable bushing immediately when
damaged. A defective protective cable bushing can lead
to overheating of the machine and to an emergency stop.
Mount the swarf protector to the machine before begin-
ning to work.
Secure the power tool with the clamping strap supplied if
there is danger of it falling, especially for work carried
out at a height, on vertical construction elements or
above the head. If there is a power outage, or the mains
plug is pulled out, the magnetic holding power is not
maintained.
When working overhead or on vertical surfaces, the cool-
ant container must not be used. Use a coolant spray
instead. Liquids penetrating your electric power tool may
cause electric shock.
Avoid touching the drilled core that is automatically
ejected by the centering pin when the working procedure
is finished. Contact with the core when it is hot, or if it
falls, can cause personal injuries.
Operate the power tool only from grounded sockets that
comply with the specifications. Do not use any connection
cables that are damaged; use extension cables with a
grounding contact that are checked at regular intervals.
A ground conductor without continuity can cause an
electric shock.
To prevent injuries, always keep your hands, clothing,
etc. away from rotating swarf. The swarf can cause inju-
ries. Always use the chip guard.
Do not attempt to remove the cutting tool if it still turns.
This can lead to serious injuries.
Hold power tool by the insulated gripping surfaces, when
performing an operation where the cutting accessory
may contact hidden wiring or its own cord. Cutting acces-
sory contacting a "live" wire may make exposed metal
parts of the power tool "live" and could give the opera-
tor an electric shock.
Beware of any concealed electric cables, gas or water
conduits. Check the working area before commencing
work, e.g. with a metal detector.
Do not machine any material containing asbestos. Asbes-
tos is cancerogenic.
Do not rivet or screw any name-plates or signs onto the
power tool. If the insulation is damaged, protection
against an electric shock will be ineffective. Adhesive
labels are recommended.
Do not use accessories which are not specifically
designed and recommended by the power tool manufac-
turer. Safe operation is not ensured merely because an
accessory fits your power tool.
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.
Please make sure that the contacting surface for the mag-
netic base is level, clean and rust-free. Remove any var-
nish or primer.
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 manually
with reduced feed. In this case, the KBM 50 auto can-
not be operated in automatic mode.
When working on materials that are not magnetizable,
suitable fixation devices, obtainable as accessories from
FEIN, e. g. suction plate, vacuum plate or pipe-drilling
device must be used.
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.
