be performed with the motor on, and
preferably without any coffee between
the grinding blades. Grind
amounts of coffee in order to determine
the optimal degree of fineness.
In the Vulcano on Demand, before
checking the fineness of the ground
coffee, grind some doses of coffee to fill
the duct between the grinding area and
the outlet. This operation must be done
whenever the grinding setting has been
changed in order to empty the duct of
the previous ground coffee. The change
of the grinding setting might vary the
weight of the doses. Therefore adjust the
doses only after the grinding setting.
In case the range of grinding adjustment
is not enough, to get the requested
grinding set, please proceed as the
following:
• close the locking slide and switch the
grinder off;
• unscrew the check pins of the coffee
bean hopper and remove it;
• remove the screws which fix the
grinding adjustment level into the
grinding adjustment disk and remove
the level;
• fit back the level and put the holes in
line with the ones of the adjustment

disk so to allow a wider grinding
adjustment;
• tighten the screws of the level into the
small
adjustment disk;
• put the hopper back;
• only after having secured the hopper
into the grinder cabinet by tightening
the pins, open the locking slide and
proceed with the grinding adjustment.

If the coffee comes out of the espresso
coffee machine very quickly, it means
the coffee is ground too coarse. Vice
versa, if it comes out too slowly, it
means the coffee is ground too fine.
Nonetheless, bear in mind that there are
many conditions liable to influence the
correct supply, such as the weight of the
portions, the compacting, the espresso
machine settings, and the cleaning of
the filters.
