Malfunction
Cause
Remedial action
The machine switches off upon a
sudden load increase.

machine also rises suddenly as
the load increases. This increase,
which occurs in the event of
sudden blockage or a kickback, is
measured and causes a
shutdown.
Release the switching button to
switch off the machine.
Afterwards, you can switch the
machine back on and continue
working.
Try to avoid further blockage.
