device must be checked. Make sure that the On/
Off switch 6 is set to off in order to avoid uninten-
tional starting of the machine.

current device. The red control light 12 indicates
that the residual current device is ready for operati-
on.
– Push the "TEST" button 11. The control light 12
must go out. Otherwise, the machine may not be
used.
Setting the Speed Range
