electricity to the motor if it becomes overheated. This device is
automatically reset when the machine cools.
The user cannot perform any operation on this device. If the device is
repeatedly activated, please consult our Technical Assistance Service, as
the motor may be damaged.
5.- Installation and set up.
Each grinder is factory tested with coffee beans to make sure that it works
properly. For this reason, you may find ground coffee in the grinder's
mechanisms.
5.1.- Grinder location.
Place the grinder on a solid, dry surface next to the coffee machine.
Never operate the grinder in wet or damp places.
5.2.- Installation and set up.
To put the hopper in place first loose
the fixing screw (T).

Página nº 8 de 25
Place the hopper as shown in the picture,
press down till the blocking device (Pos 4)
enters the hole (R) in the hopper neck.
For compliance with safety requirements,
tighten the hopper fixing screw (T) using a
5mm allen wrench.
Insert the coffee grounds tray as shown
in the illustration.
THE GROUND COFFEE SPILLED ON THIS
TRAY MUST NOT BE PUT IN THE HOPPER.
The grinder has a Ø57mm press tamp
placed in the front of the machine and
another Ø53mm press tamp is included in
the box along with the power cord and the
grounds tray. Check which one best matches
the filter-holder of your coffee machine and
change it if needed.

To connect the grinder to the power supply, proceed as follows:
- The grinder's electrical connection must be properly protected by current
limiting circuit breakers, a differential switch and a ground connection,
according to current safety regulations.
- Make sure that the voltage and frequency of your establishment match
those indicated on the grinder's rating plate.
- Plug the grinder into the electrical socket. The display will show the
message:
- Open the hopper lid and pour the coffee beans into the hopper. NEVER
put GROUND COFFEE in the hopper
- Make sure that the hopper closing device (Pos. 2) is open.
- Select the desired coffee dose, pressing the corresponding button:
Key F: “ 1 CUP ” o key G: “ 2 CUPS ”.
- Insert the filter-holder from your coffee machine in the filter-holder rest
(Pos. 9) as far as it will go, pressing the switch.
- The corresponding dose is deposited in the filter-holder.
- Compact this dose using the press tamp (Pos. 8) to level off the ground
coffee before placing it in your coffee machine.
- The grinder automatically grinds the corresponding dose.
- Use the ON / OFF key (Pos. D) to turn on and off the grinder. In Off
position, the grinder remains in stand-by mode.

5.3.- Basic settings.
5.3.1.- Grinding fineness setting.
The grinder is adjusted in the factory to be used with espresso coffee. It
simply needs a bit of fine tuning to adapt it to the characteristics of the
coffee used in your establishment. Grind enough coffee to fill your filter-
holder with a normal dose and brew a cup of coffee with your coffee
machine. If the result is unsatisfactory, modify the grinding level as
follows:
If coffee flows too slowly, press the
blue button (Pos. 3) and turn the
grinding adjustment handle in the
blue arrows direction, pushing the
lever (Pos. 5)
If coffee flows too fast, press the
red button (Pos. 3) and turn the
handle in the opposite direction,
signalled by the red arrows.
Fine adjustments can be achieved moving the handle just one click.
Take notice of the functions allowed by those buttons (Pos. 3)
 Blue button pressed  coarser grinding.
 Red button pressed  finer grinding.
 No buttons pressed  grinding adjustment blocked.

Página nº 11 de 25
Brew more coffee for additional
tests, repeating the steps above until
achieving optimal results in the cup.
Around the handle of the grinding
adjustment there is a scale and a dial to
note the settings.
For easier use, once the grinding is adjusted
you can attach the sticker provided along
with the set of accessories, matching the
zero of the sticker with the dial (see figure).
Later adjustments will be easier to control.

5.3.2.- Coffee dosage setting.
The grinder is set at the factory
for a grinding time of 1.8 seconds for 1
cup of coffee and 3.1 seconds for 2
cups of coffee. If the dose obtained is
not what you want in your coffee
machine, modify the dose as follows:
- Press the 1 cup key (Pos. F) for 1.5
seconds until the message “C1:
1.80” appears on screen.
- Press the keys “–” or “+” (Pos. B, C)
until reaching the desired value.
- Press the 1 cup key again to confirm the new dose.
- Perform the same operation with the 2 cup key (Pos. G).
Program in first place the dose for 1 cup. Notice that the dose for 2 cups
is limited to double of the programmed dose for 1 cup.
5.3.3.- Filter-holder detection system setting.
The grinder has several systems for selecting 1 or 2 cup doses, which may
be programmed by your Technical Assistance Service:
- Automatic filter-holder identification. (Factory
programmed setting.) This patented system
automatically detects 1-cup or 2-cup filter-
holders.

Página nº 13 de 25
For the system to work, a tag or identifier must be fixed to the 2-cup
filter-holder: the grinder distinguishes between a filter-holder with this
tag (and provides the dose for two cups of coffee) and filter-holder
without tag (for which it provides the dose for one cups of coffee), with
no need for any action on the part of the operator. (See Appendix I).
- Key selection, 1 Cup: When the filter-holder is
inserted, it receives the dose for 1 cup of
coffee. To obtain a dose for 2 cups of coffee,
press the 2c button before inserting the filter-holder.
- Key selection, 2 Cups: Without pressing any
button the filter-holder receives the dose for 2
cups of coffee. Press the 1c button before
inserting the filter-holder for the single dose.
- Key selection, last service. Without pressing any key the filter-holder
receives the same dose as in the last service.
- Dose selection by pressing filter-holder single or
double click:
o Press filter-holder once (single click): One
cup of coffee.
o Press filter-holder, release and press again (double click): Two cups
of coffee.

8.- Cleaning.
Before proceeding to clean any grinder parts, disconnect from the power
supply by unplugging the electrical cord from the back of the grinder.
8.1.- Cleaning the bean hopper
Close the inlet hopper and loosen the screw (T) that attaches the hopper
to the grinder (See the illustration). Pull and turn the Hopper fixing device (Pos.
4) until the position sown above (continuous line horizontal). Remove the
hopper from the grinder and empty any remaining coffee.
Clean the hopper with soap and a cloth soaked in water to remove the
residual oils from the coffee beans and dry it carefully.
To put the hopper back in place, pull the fixing device (4) and turn it 90º to
the usual position (continuous line horizontal). Put the hopper in the grinder
and push it down until the fixing device fits in the hole (R) of the hopper neck
(see image at paragraph 5.2).
