Safety systems

Start lock-out
The appliance can only be switched on if
the bowl has been inserted and turned until
it locked into place, or if an accessory has
been secured to the main drive with the
bevel gear, and if the swivel arm is locked
into the lower position.
Automatic power-on safety lock
If the power is interrupted, the appliance
remains switched on, but the motor does
not start again when power is restored.
To switch back on, first turn the rotary
switch to y, and then switch on again.
Overload protection
The overload fuse will switch the motor off
automatically during operation. One pos-
sible cause may be processing too much
food at once.
Swivel arm protection device
The swivel arm will not unlock and move if
an accessory is fitted to the rear drive.
