For switching the magnet ON
(figure 8).
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 sur-
faces; it could lead to a permanent reduction
of the magnetic holding power.
When working, always use the magnetic
base; ensure that the magnetic holding
power is sufficient.
– When the green magnetic holding-power
indicator lights up permanently, the mag-
netic holding power is sufficient and the
machine can be operated with normal
feed.
– When the green magnetic holding-power
indicator 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 vac-
uum plates or pipe drilling devices, which
are available as accessories, must be used.
Observe the corresponding operating
instructions for these.
When working on steel materials with a
material thickness of less than 12 mm /
1
/
in, the workpiece must be reinforced
2
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 no current flows through
the magnet, the motor switches off.
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, a protective cir-
cuit prevents automatic restarting of the
motor. Restart the motor again.
