MAINTENANCE
General instructions
Before starting any adjusting operations re-
quiring parts of the unit to be removed, the
machine must always be switched off.
• The operations described in the
proceeding pages should be carried out
only by qualified personnel, who are
trained in the correct use of the machine
according to the standards in force and
who have the specific knowledge of the
machine functioning from a point of view
of electrical safety and health regulations.
The grinder is fitted with a sensor that counts
the number of rotations of the grinding
wheels, allowing the control software of the
machine to determine the number of rota-
tions and thus the grams of coffee for each
single selection.
With the programming procedure, it is pos-
sible to set the grams (6 to 12 gr) of ground
coffee (rotations of the grinder) for each se-
lection.
Important:
Never touch the adjusting knob of
the grinder.
Always call a technician for adjust-
ment / calibration of grinder!
The grinder requires a period of 50
selections to allow the grinder to
“run in”. After this period the coffee
empty detection becomes stable. A
complete coffee bean canister con-
tains 250 - 300 selections so the
grinder should be correctly “run in”
by the time the coffee bean
canister is empty for the first occa-
sion.
