4. Safety Devices
Thermal overload circuit breaker
The motor of the grinder is protected by an overload circuit breaker,
which interrupts the electric circuit of the motor when the device is
subjected to electric overloading. To be able to re-start the grinder, the
reset button at the back of the casing must be pressed (Pos.9).
The user has no influence whatsoever on this op-
eration. In case of repeated tripping of the circuit
breaker, contact a service partner since this could
cause damage to the motor winding.
Finger protector / Magnet holder
A combined finger protector / magnet holder is fitted in the hopper of
the grinder. It is supposed to prevent the user from reaching into the
running grinding mechanism. At the same time, it also prevents fer-
rous foreign objects from getting into the grinding mechanism. Every
now and then clean the magnet since adhering foreign objects could
block the coffee supply.
Magnet Switch
The key plate with the grind adjustment scale (Pos. 4) is secured by a
magnetic switch. Once that key plate is removed the grinder cannot be
started anymore.
Never remove the finger protection!
5. Set-up and Basic Adjustment
A grinding test run is carried out on each grinder in the factory. This is
why you may find ground coffee residue in the grinding mechanism!
5.1 Setting-up Area
Place the grinder on a level surface free of vibration.
Never operate the grinder in moist, or even worse,
in wet surroundings.
5.2 Installation
You have received your grinder in operating condition. Now you only
need to connect it to a power supply system. Proceed as follows:
Protect your device with a separate pre-fuse (not
included in the scope of supplies) according to the
information provided under 2. Technical data.
Make sure that the pre-fuse is not overloaded by
other consuming devices (e.g. fan forced heaters,
deep freezers).
Determine whether the mains voltage and fre-
quency correspond to the information on the rat-
ing plate.
Insert the plug into the available grounded outlet.
