9.2. USAGE
Through the program menu (section 10.4.3),
it is possible to select three distinct functional
modes: PUSH, DETECTION and TOUCH.
9.3. PUSH MODE
In the PUSH mode, a pre-programmed single,
double or triple dose can be set by simple
pressing the corresponding icon on the TFT
screen ( ).
The preselection of a single, double or triple
dose will remain active until it is changed by
pressing one of the three numbered icons. This
preselection is reflec ted on the TFT screen

grinding cycle begins, a timer countdown will
begin on the TFT screen ( ), which will count
down the timed dose cycle to zero.
9. OPERATION
NOTE: If the coee
throughput is very low, this
is because the coee is
being ground very fine. If
the throughput is very high,
this is because the coee is
being ground very coarse. A
perfect Espresso is produced
when the grinding gives an
infusion of 25 ml of coee in
25 seconds using about 7 g of
ground coee.
NOTE: It is recommended
that this operation be
performed, when changing
to a finer grinding, with the
motor running, to prevent
coee from building up
between the burrs and
blocking the grinder.
8.4. PREPARATION OF THE
PORTAFILTER DETECTOR (OPTIONAL)
1. Place the detector on the double portafilter
(Fig. 1).
2. Check that the detector ring tab is properly
closed (Fig. 2).
