For switching the magnet ON
(JMU 137 QW (**), JMU 137 MQW (**),
JMU 137-2 QW (**)) (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 button on the control
panel lights up permanently, the magnetic
holding power is sufficient and the machine
can be operated with normal feed.
– When the Magnet button on the control
panel flashes, the magnetic holding power
possibly is insufficient and the machine
must be operated with reduced feed.
When working non-metal materials, suitable
manufacturer 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 /
the workpiece must be reinforced 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 defec-
tive, the motor will not start.
