LADENMÜHLEN SHOP GRINDER

9.2.1.2 Removing the grinding disc in the stationary ﬂange,

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 qualiﬁed 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.
