For switching the magnet ON
(figure 11).
Pay attention that the set-up surface for the
magnetic foot is flat, clean, rust-free and ice-
free. Remove varnish, putty/filler layers and
other materials. Prevent an air gap between
the magnetic foot and the set-up surface. 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 signal lamp lights up per-
manently, the magnetic holding power
possibly is sufficient and the machine can
be operated with normal feed.
– When the green signal lamp flashes, the
magnetic holding power possibly is insuffi-
cient and the machine must be operated
with reduced feed.
When working on steel materials with a
material thickness of less than 12 mm /
the workpiece must be reinforced with an
additional steel plate in order to guarantee the
magnetic holding power.
Work only with the absolutely required
amount of feed. Excessive feed can lead to
breakage of the application tool and loss of
the magnetic holding power.
When the power supply is disconnected
while the motor is running, the electronics
prevent automatic restarting of the motor.
Restart the motor again. Adjust the gear set-
ting only when the machine is at a complete
stop or when the motor is running down. Do
not stop the drill motor during the drilling
procedure. Remove the core drill bit from the
drill hole only while the drill motor is run-
ning. If the core drill bit gets jammed/stuck in
the material, stop the drill motor and carefully
rotate out the core drill bit turning in coun-
terclockwise direction. After each drilling run,
remove the chips and the drilled out core. Do
not touch the chips with your bare hands.
Always use a chip hook. Danger of burning!
The surface of the magnet can reach high tem-
peratures. Do not touch the magnet 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 chips after having drilled
through each layer. Do not use the magnetic
core drill unit when the cooling-lubricant sys-
tem is defective. Check for tightness against
leaks and for cracks in the hoses. Prevent liq-
uids from entering or penetrating electrical
components.
