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.
