1.2 SAFETY REGULATIONS
Machine design has taken into account all reason-
able user safety precautions; nevertheless, particu-
lar conditions of installation and/or handling may
create unforeseen situations beyond the installer’s
control which will require case-by-case evaluation of
residual risks. We recommend keeping the following
in mind:
• Always handle the machine with care to avoid the
danger of its falling.
• The packing materials (carton, cellophane, sta-
ples, polystyrene, etc..) can cut, wound or create
hazards if used improperly or handled carelessly.
Store such materials out of reach of children and
irresponsible persons.
• This symbol on the appliance or package means
that the appliance must not be considered as
normal household refuse but that it must instead
be delivered to an appropriate collection centre
for the recycling of electric and electronic appli-
ances. Make sure that this appliance is disposed
of correctly and you too will be making your
contribution to the prevention of negative effects
on health and the environment, which could
otherwise be caused by inadequate disposal.
Recycling materials helps to preserve our natural
resources. For more information about how to
recycle this product, you can contact your local
council office, local refuse disposal service or the
retailer from whom you purchased the appliance.

• Before carrying out any installation or adjust-
ment process, be sure to have read and thorough-
ly understood the warnings in this manual.
• The company cannot be held liable for any dam-
age to people or property resulting from failure
to respect the instructions concerning safety,
installation and maintenance contained in this

replaced by the user. In the event of damage,
switch off the appliance and only contact profes-
sionally qualified technicians for its replacement.
• Should you decide to no longer use this type
of appliance, we recommend that you make it
inoperative: unplug the appliance from the mains
socket and cut off the power cord.
• All defects and/or anomalous machine behaviour
should be reported immediately to authorized
installation and/or maintenance personnel.
• Before connecting the machine, check that elec-
trical power supply corresponds to the specifica-
tions on the data plate.
• Should the machine plug not be compatible with
your socket, have the plug replaced with a suit-
able type by a qualified technician, who should
also check that the section of the wires supply-
ing the power outlet is suitable for the machine
power requirements.
• Avoid use of multiple-plug adapters and exten-
sion cords.
• The ground wire must be connected; the electri-
cal system must meet the standards set by local
safety laws and regulations.
• The machine must be installed only by author-
ized, qualified personnel.
• Check that the machine components have suf-
fered no damage during shipping; in the case
defects or anomalies are found, interrupt instal-
lation and request replacement.
• Never obstruct the fan grids.
• Never insert objects into the fan grids.
WARNING
Do not touch the heating element
or the upper grinder holder during
machine functioning, as they might
reach high temperatures.

1.3 APPLICATIONS AND USE
• This grinder dispenser has been devised for pro-
fessional use by trained personnel.
• The grinder/dispenser must be used only for
the application for which it was designed; that
is, grinding roasted coffee beans. Any other use
must be considered improper and therefore dan-
gerous.
• The manufacturer shall not be held responsible
for damages deriving from improper, erroneous
or unreasonable use of the machine.
• The appliance must not be used by children
or people with reduced, physical, sensorial or
mental abilities. It must also never be used by
people without the necessary skills and experi-
ence unless under supervision or during training.

at any time.
• The machine is not designed for use in extreme
environmental conditions and in any case at tem-
peratures outside the -5°C to +30°C range.
• The user must respect the general safety regula-
tions in force in the country in which the machine
is installed as well as the rules of common sense,
and shall be responsible for ensuring that period-
ic machine maintenance is correctly performed.
• The persons installing and using the machine and
performing machine maintenance shall inform
the manufacturer of any defects or damages due
to wear that might jeopardize the original safety
features of the machine.
• The installer shall be responsible for checking
that the machine is installed in tolerable environ-
mental conditions such as to not to create health
or safety hazards for those using the machine.
• Any responsibility deriving from components
manufactured and installed on the machine shall
be assumed by the respective manufacturers;
responsibility attributable to the persons author-
ized to use the machine shall be assumed by the
customer.
• Recommended period of use are Ton 30 sec and
Toff 60 sec.
• The machine is designed for 24-hour intermittent
service. The machine components are designed
and built to ensure at least 1000 hours’ operation.

center and request use of original spare parts.
• Non-observance of the above precautions may
make the machine unsafe for future use.
• Do not leave the machine switched on when not
in use. Unplug the machine when not in use.
• Do not obstruct the ventilation and/or heat dissi-
pation openings and/or slits nor introduce water
or any other liquids into same.

from the use page, keeping the respective sensitive
areas pressed down.
NOTE
My coffee 6 is the "Barista mode", a
different scenario where one dose is
shown in the center of the display and
it is possible to change directly.
When ON, the home page displays:

2.1.5 GRIND COFFEE
To grind coffee press one dose key or the touch
screen display (this light up) to choose a dose.
Timer version
1 Place the filter holder on the fork.
2 Push the filter holder forward until it comes in
contact with the button to pour out the ground
coee through the spout.
Gravimetric version
Hook and release the filter holder on the fork.
Machine will carry out tare and will begin to deliver
coffee up to the set weight.
Leave the filter holder until the grinder finishes, oth-
erwise it never stop.
NOTE
There may be an excessive distribution
of coffee in the filter holder for the first
10 - 20 ground doses.
If it persists, check the clump crusher
(see the relevant paragraph 3.3.1).

2.1.6 GRINDING SIZE
Use the knob, turning it clockwise for finer grinding
or anti-clockwise for a coarser grinding.
WARNING
Grinding setting must be performed
gradually, grinding a little coffee each
time that the knob is turned by two
digits (notches).
The machine may seize up if the knob
is moved by one turn while the motor
is switched off.
NOTE
The setting has no stop points and
each turn of the knob corresponds to a
movement of 0.4 mm of the burrs.
The machines equipped with resetta-
ble knob can be set to zero at a preset
grinding point by holding the top part
of the knob in position and using the
ring nut on the base.
