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.
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 red warning light in the button of the con-
trol panel is not lit and when the main switch in the
drill stand is lit permanently, the magnetic holding
power is sufficient and the machine can be operated
with automatic feed.
– When the red warning light in the button of the con-
trol panel and the main switch flash, the magnetic
holding power possibly is insufficient and the machine
must be operated with manual feed.
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.
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.
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. Check for proper seal
against leaks and for cracks in the hoses. Prevent liquids
from entering or penetrating electrical components.
KBM80auto: Do not use the automatic feed when tap-
ping.

symbol, and then
symbol.
Corrective Action
– Wait until the "asym-
metrical flashing" stops
and the motor can be
switched on again.
– Check the mains volt-
age.
– Check the connection
hose between drill
motor and drill stand
for damage.
– If this error occurs fre-
quently, send the
machine to your FEIN
customer service agent.
– Pull the mains plug and
wait until the magnet
switch stops flashing.
– If the error still occurs
when putting into
operation again, send
the machine to your
FEIN customer service
agent.
