WARNING
To avoid the blockage of the spout (11) hold the portafilter on the fork (10).
7.2 REGULATION OF THE GRIND
To adjust grinding fineness, it is necessary to open the hatch (7) and use the knob (14)
(see Fig. 5) turning it clockwise for finer grinding, or anticlockwise for coarser grinding.
This adjustment does not have any stop points and each turn of the knob corresponds to a
movement of 0.4 mm of the grinders.
Grinding fineness is factory set, with the grinders first adjusted so that they touch each
other (0) and then moving the grinders so that they are at a distance to provide an average
grinding fineness for espresso coffee. Grinders with re-settable adjustment knob can be
set to zero at an established grinding point by holding the top part of the knob in position
and using the ring nut on the base of the knob itself. Caution: grinding fineness adjustment
needs to be performed gradually, grinding a little coffee each time that the knob is turned by
two numbers (notches). The machine may seize up if the knob is moved by one turn while
the motor is switched off.
7.3 REGULATION OF THE PRESSING POWER
(on the appropriate model)
To adjust pressing force, it is also necessary to open the hatch (7), then to use the graded
screw (15) (see Fig. 6), turning it clockwise to increase the pressure or anticlockwise to
reduce it.
7.4 PROGRAMMING OF THE MACHINE
The first time you turn on the machine, it will be on the mode programmed
at the factory. Every time you turn on the machine it will set itself to the last
settings prior to disconnecting.
7.4.1 DOSE SELECTION IN AUTOMATIC MODE
Place the portafilter and press fully the microswitch placed behind the fork
machine will start after a moment and will not stop till the end of the programmed time, even if
the portafilter is removed from the fork.
When the machine finishes the grind it will automatically be in the single impulse phase.
The button will flash for a period of time and is programmable (See Par. 7.4.6
PROGRAMMING OF THE SINGLE IMPULSE), during this period in time the user can add
a little coffee by pressing the flashing button, or, place the portafilter in the pressing base
and press (see Fig. 9).
7.4.2 DOSE SELECTION IN MANUAL MODE
Place the portafilter and push completely the microswitch at the base of the fork, on the display the
writing "CHOOSE DOSE" will appear while all three dosage buttons will flash. At this point, press
the dosage button of choice or the continuous grind button and the machine will start operating.
