a crema, while grounds that are too fi ne result in strong, dark
coff ee without a crema;
- If the coff ee does not respond to your desired requirements,
adjust grind fi neness by pressing the ring block button (Fig. 2-1)
and turning the regulation knob (Fig. 2-3) counter- clockwise
for a fi ner grind or clockwise for a coarser grind;
- Repeat the operation until you have obtained the desired
quality of coff ee.
Recalibration of the grind is typically necessary after a change
in coff ee. Minor adjustments may be required throughout use to
accommodate for changes in freshness of the beans.

9. INFORMATION FOR SERVICE TECHNICIANS
9.1. Replacement of burrs
Although manufactured in tempered steel, the burrs are subject
to wear and tear.
Their lifespan is infl uenced by the amount of coff ee ground, its
hardness and degree of roasting, as well as the quantity and purity
of the coff ee beans.
Small stones and various impurities have a marked abrasive action
which signifi cantly reduces the lifespan of the burrs.
When grinding time becomes noticeably longer or the grind
becomes irregular, the burrs should be replaced as follows:
- Pull the hopper locking slide (Fig. 1–4);
- Start the grinder to grind the coff ee remaining between the
burrs;
- Once grinding has fi nished, turn off the machine and unplug
from the power source;
- Remove the regulation knob (Fig. 1–3);
- Turn the upper burr-holder (Fig. 4–1) counter-clockwise until
the upper grinder holder ring nut is completely out of the head;
- Unscrew the screws (Fig. 4–2) and remove the burrs (Fig. 4–3)
from the burr-holder;
- Carefully clean the burr supports, the burr-holder thread and
its housing;
- Position the new burrs in their holders and block them fi rmly
in place;
- Reassemble the machine, performing the previous steps in
reverse;
- Calibrate the new burrs and reset the counter.
9.2. Calibration of grinder burrs
To be performed after burr replacement
The grinders are tested with a medium grind setting, and need
to be readjusted. This operation should be carried out with the
bean hopper empty.
Remove the protection lid (Fig. 1-5), hold down the adjustment
unlock button (Fig. 2-1) and at the same time slowly turn the
adjustment knob (Fig. 2-3) counter-clockwise until the burrs
brush against each other. Release the button, turn the numbered
ring (Fig. 2-2) so that the starting point 0 is frontal; move the
adjustment knob (Fig. 2-3) in the opposite direction (clockwise).
9.3. Technician menu
Must be performed by a qualifi ed technician.
The access to the technician menu is given by switching off the
grinder. Switch on the main switch (Fig. 1-9) while pressing the
