The machine is factory calibrated with an es-
presso grinding. To adjust the granulometry,
use the continuous dose and a precision scale
to weigh the exact grammage. Every time a
grinding adjustment is required, the rst two
double doses must be discarded because they
might still contain parts of the previous grinding
adjustment. After pressing the co󰀨ee and check-
ing that the extraction time is the desired one,
proceed with the adjustment of the times of the
programmed doses.
To modify grinding: Rotate the adjustment
knob clockwise for a FINER granulometry and
anticlockwise for a COARSER granulometry
(g._5.4). Adjust the grinding with the motor
switched on if there is co󰀨ee between the grind-
ers, and with the motor switched o󰀨 if there is
no co󰀨ee.
The adjustment from coarse to ne
is best done while the machine is
grinding or with an empty grinding
chamber.
■ Activate the device by moving the switch to
the I- ON (3 - g._5.3). When starting the
device, a short welcome message appears
on the display and after a few seconds one
of the pre-set functions appears; to switch
from one function to another, press the dose
selection button .
5.2 Grinding
adjustment
At night or when there are no oper-
ators in the room, move the switch
to the O - OFF (see gure 4.4).
Never operate without the
hopper or without its cover.

The device is equipped with a digital dose
time adjustment.
Pressing the dose selection button
in the operation menu allows you to choose
between single, double, triple or continuous
dose. To change the time of the programmed
doses make sure that the “PADLOCK” symbol
is in the open position .
If it is not, press the dose selection button
for 3 seconds; adjust the dose using
the “ ” or “ ” buttons.
Press the dose selection button for 3
seconds and return the “PADLOCK'” to the
closed position to prevent any change
in the time settings.
Please note that each time you adjust the
grinding, you must check that the quantity of
ground co󰀨ee has remained as desired.
g_5.5
g_5.6
It is also recommended to grind
and use a few grams of coffee
every time the granulometry is
altered. This procedure is useful
to eliminate the small amount of
pre-ground co󰀨ee present in the
appliance. If the machine dispens-
es co󰀨ee slowly, the ground co󰀨ee
is too ne, while if it is too fast, the
ground co󰀨ee is too coarse. Many
factors may inuence the dispens-
ing of co󰀨ee, including the quality
of the co󰀨ee, pressing, the adjust-
ment of the espresso machine, the
cleaning of the lters and climatic
conditions.
5.4 Fork adjustment
All models are supplied with a fork height ad-
justment device. To change the height, loosen
the screws by half a turn 1 - g._5.5) and move
