ADJUSTING GRINDING
In order to achieve finer or coarser grinding
and therefore vary the granulometry, use the
adjustment disk located under the hopper . To
increase the coarseness of the ground coffee,
the adjustment disk must be rotated clock-
wise, pressing the adjustment disk lock down-
wards, to decrease turn the disk anticlockwise .
The adjustment must be performed with the
motor on, and possibly without coffee between
the grinding blades .
It is advisable to grind small amounts of coffee
to facilitate a visual check of optimum granu-
lometry and, if required, adjust the grinding
adjustment disk . If the coffee comes out of the
espresso coffee machine very quickly, it means
that the coffee is ground too coarse . Vice versa,
if it comes out too slowly, it means the coffee
is ground too fine . Nonetheless, bear in mind
that there are many conditions liable to influ-
ence the correct supply, such as the weight of
the portions, the compacting, the espresso ma-
chine settings and the cleaning of the filters .
When the adjustment disk is moved to change
the grinding mode, the buttons on the display
will turn green, and then the auto-calibration
system will be activated . The next 3 dispensing
operations will be required to recalculate the
weight of the doses . The yellow gear icon with
1 or 2 blue squares will indicate that the subse-
quent doses will be within the tolerance of the
set nominal doses .
SAFETY DEVICES
Thermal overload protection
The grinder-doser motor is protected against
overheating resulting from overcurrents by
a thermal overload protection which, when
tripped, cuts off the power supply to the mo-
tor . If the thermal protection device should au-
tomatically turn on in the event of anomalous
operation (such as the grinding blades jam-
ming), turn off grinder-doser using the On-Off
switch, unplug it from the mains, and contact
skilled technical personnel . Never perform any
work on the grinder-doser while it is attached
to the mains, in order to prevent the motor
from turning on suddenly . If the grinder-doser
overheats as a result of the motor stopping,
allow the grinder-doser to cool down before
performing any repair work .
Adjustment disk lock
In order to prevent the adjustment disk from
being removed, which would make the rotating
parts accessible, there is an anti-unscrewing
adjustment disk lock (safe) positioned under
the adjustment disk .
Coffee outlet guard
The coffee outlet guard must always be fixed to
the doser unit using the relevant screws, which
must never be removed by the user . The re-
moval of the coffee outlet guard can be done
by skilled technical personnel only after dis-
connecting the grinder-doser from the power
supply by unplugging . Before reconnecting the
grinder-doser to the power supply, replace the
safety device .
NOISE LEVEL
EEC Countries - The maximum noise emission
of our coffee grinders and grinders/dosers
measured in UNI EN ISO 3741 reverberating
chamber in compliance with the EN 60704-1
regulations, is compliant with the EN 60704-1
: 1998 and EN 607043 : 1996 regulations . The
equivalent level of noise exposure of a worker,
exclusively related to limit of 240 min . per eight
hours of use of the appliance, is equal to 78
dB(A), in compliance with ED 86/188/EEC and
ED 200311 0/EEC . Therefore, when operating
the appliance, no provisions need to be taken
in order to prevent such risks arising from
noise exposure in the workplace (articles 3-8
of ED 2003/10/EEC) .
