Restarting protection
NOTE
► The machine stops automatically if the magnetic clamp is
switched o󰀨 or in the event of a power failure.
In order to prevent unexpected starting of the machine when the
magnetic clamp is switched on again or when the power supply
returns after a power failure ("restarting protection"), the machine
must be switched on at the ON/OFF switch again.
Magnet indicator
The magnet indicator provides a visual control of the magnet's
clamping force.
■ Magnet indicator is lit GREEN:
The magnet's clamping force satises the minimum require-
ments. Machining can be carried out.
■ Magnet indicator is lit RED:
Insu󰀩cient magnet clamping force. Machining must not be
carried out with the machine. This can be the case in the event
of insu󰀩cient material thickness, uneven surface or due to
paint, scale or zinc coatings.
Thermal overload protection
The machine is additionally equipped with thermal overload pro-
tection. If the machine becomes too hot, it switches o󰀨 automati-
cally.
Carry out the following steps before continuing to work with the
machine:
 Remove any blockages that may have occurred.
 Allow the machine to run at no-load speed
for approx. 2 minutes.
The machine is then ready for operation again.
