lation operations must be carried out by qualified

facturer of the grinder-doser.
To obtain good quality espresso coffee we sug-
gest the following:
not to store large amounts of coffee beans. to
observe (in any case) the expiry date indicated
by the producer.
to grind an amount of coffee based on use, pre-
pare the amount contained in the doser and if
possible use it before the end of the day;
never to buy (if possible) already ground coffee,
as it expires quickly. if necessary, to buy it in small
vacuum-sealed packages.
to fill the filter with a dose of ground coffee
(about 6-7 gr.) and press it with the special coffee
presser. Hook the portafilter to the delivery group.
To prevent the seal from wearing too soon,
!
clean the edge of the filter before engaging
the portafilter on the delivery group. Do not
excessively tighten the portafilter to the dis-
pensing group.
