ADJUSTING THE GRADE OF GRINDING
When a variation in the grade of grinding is desired, turn
the relevant adjusting knob on the grinder (see Fig. S) and
more specifically:
- turn the knob anticlockwise for coarser grinding;
- turn the knob clockwise for finer grinding.
OPERATING MODES
Three different operating modes are provided for the
machine, accordingly the buttons may have different func-
tions based on the preset mode of the buttons.
The available operating modes are as follows:
DISPLAY FUNCTIONS

Maintenance mode
"Maintenance" test dispensing

NORMAL OPERATING MODE
When switching the machine on, the message "Rev. X.X"
(X.X indicates the software release number) is displayed
for a few seconds, after which the machine goes into
normal operating mode.
The massages displayed according to the current opera-
tion are as follows:

For optimum results, it is good practice to vary the grade
of grinding with the coffee grinder motor running.
N.B.: After adjustment of the grade of grinding, at least
2 test selections must be performed in order to check
the new grade of the ground coffee:
the finer the grade of grinding the longer the time neces-
sary for dispensing the coffee and vice versa.
ADJUSTING THE COFFEE DOSE
The dose adjusting lever can be positioned in one of the 6
reference notches bearing in mind that:
- the dose is increased by lifting the lever:
- the dose is reduced by lowering the lever:
- every notch changes the dose by approx. 0.25 g.
In addition, when the lever is fully rotated upwards, the
ratchet can be released from the groove in the dose
regulator (see Fig. 15) and replaced into a different groove
to change the average dose setting to:
- low 6 g. ± 0.5
- medium 7 g. ± 0.5
- high 8 g. ± 0.5
To take the dose just remove the coffee unit and press
button "6" from "Special functions" of the "maintenance"
menu (see relevant section).
Important notice!!!
To refit the coffee unit, pay special attention to the
piston position. Reference notches on the external
disk and on the unit case should match (see Fig. 17).
