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 influenced by the amount of coffee ground, its
hardness and degree of roasting, as well as the quantity and
purity of the coffee beans.
Small stones and various impurities have a marked abrasive
action which significantly 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 coffee remaining between the
burrs;
- Once grinding has finished, turn off the machine and unplug
from the power source;
- Empty the bean hopper (Fig. 1–2);
- Remove the regulation knob (Fig. 1–3);
- Turn the upper burr-holder (Fig. 4–1) counter-clockwise until
the head emerges completely;
- 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 firmly
in place;
- Reassemble the machine, performing the previous steps in
reverse.
- Calibrate the new burrs.
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. 1b-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).
