9.2.1.2 Removing the grinding disc in the stationary fl ange,
without screws
Procedure:
1. Place a screwdriver in the groove (1) at the grinding disc (2).
2. Rest the tip of the screwdriver on the facing edge and use it to lever
the grinding disc.
3. Once the grinding disc has overcome the magnetic attraction, it can
be removed manually.
Installation of the grinding disc is carried out in reverse order.
HINT
Ensure that grinding discs are positioned correctly during installation.
Observe the position of the driver!
HINT
Ensure that all the mating surfaces
are absolutely clean before reas-
sembly! Failure to do so will result
in inconsistent grinds.
9.3 Maintenance work on the mains power supply
HINT
Work on current-bearing assemblies or components must only be car-
ried out by MAHLKÖNIG technicians or by a qualifi ed specialist electri-
cian. Please see chapter 12 “Electrical wiring diagrams” for the circuit
diagrams.
Only open the grinder when it is completely idle.
Before opening the casing, switch off the machine
and disconnect the plug from the mains socket.
10 Protection devices / Faults
10.1 Protection devices
The grinder is protected by a temperature monitor in the motor coil and
equipped with additional over-load protection (Klixon). A micro switch
integrated in the upper part of the machine prevents the motor from
starting up if the cover plate or the bean hopper has been positioned
incorrectly.
Temperature monitor
The temperature monitor switches the grinder off as soon as the motor
coil is too hot. This can occur for example if the system is in continual
use. After the grinder has cooled down, the machine is ready for service
again.
Overload protection / Klixon
The overload protection is tripped if the current accepted by the grinder
is too high. This can occur if the grinding discs are blocked.
