4) FUNTIONING
Coffee grinding adjustment
(to be always carried out by authorized and qualified personnel)
The grinding adjustment must be carried out when the grinder is in function.
-to obtain a finer grinding size, rotate the regulation handle clockwise (towards /-);
-to obtain a larger grinding size, rotate the regulation handle anti-clockwise (towards /+);
The numbering on the regulation handle indicates the grinding variations.
A new grinding adjustment - which must be carried out by a qualified personel after having disconnected
the tension from the appliance - must be carried out each time the grindstones are replaced.
Coffee dose adjustment
(to be always carried out by authorized and qualified personnel)
- Remove the hopper lid
- fill the hopper with coffee beans
- Dispense the coffee dose
SINGLE DOSE: The motor for the programmed time is actived by pressing 1 DOSE push-button.
It is also possible to stop instantaneously the grinding phase by pressing the push-button 1 DOSE again
during the operation.
DOUBLE DOSES: The motor for the programmed time is actived by pressing 2 DOSES push-button.
It is also possible to stop instantaneously the grinding phase by pressing the push-button 2 DOSES again
during the operation.
- Use the special coffee presser fixed on the grinder to press slightly and level the ground coffee
to eliminate any coffee excess from the filter holder;
- Insert the filter holder into the brewing group of the espresso coffee machine to prepare a coffee.
Coffee dose programming
SINGLE DOSE: Disconnect the machine. Switch it on again and, while the blue led switches blink, press
them both at the same time. Upon the emission of three short sounds the grinder is programmable.
Press push-button 1 DOSE to start the grinding phase and release it only when the desired quantity has
been reached (i.e. aprox. 3 seconds to dispense 7 grams). Upon the release of the push-button a longer
"beep" soundssignals the programming has been saved. The microprocessor installed on the card will
memorize the time passed between the pressure and further release of the push-button 1 DOSE and this
will be the time for the single dose grinding until further programming.
DOUBLE DOSES: Disconnect the machine. Switch it on again and, while the blue led switches blink, press
them both at the same time. Upon the emissionof three short sounds the grinder is programmable.
Press push-button 2 DOSE to start the grinding phase and release it only when the desired quantity has
been reached (i.e. aprox. 6 seconds to dispense 14 grams ). Upon the release of the push-button longer
"beep" sound signals the programming has been saved. The microprocessor installed on the card will
memorize the time passed between the pressure and further release of the push-button 2 DOSES and this
will be the time for the double doses grinding until further programming.
