8.2. Adjusting grinding
• In order to achieve finer or coarser grinding and
therefore vary the granulometry, use the adjust-
ment disk located under the hopper. To increase
the coarseness of the ground coffee, the adjust-
ment disk must be rotated clockwise, pressing
the adjustment disk lock downwards, to de-
crease turn the disk anticlockwise.
• The adjustment disk can remain in selected po-
sition without locking. The motor must be turned
on during adjustment operations and there
should be no coffee between grinding blades.
grind a small amount to determine the optimum
granulometry. Before electronic machine check-
ing optimum granulometry, grind few amount
coffee to fill the tube between the flooded area
and the coffee powder outlet. This step must be
performed to clear the remaining coffee powder
from the pipe. coffee powder may change the
dose weight.
• It is advisable to grind small amounts of coffee
to facilitate a visual check of optimum gran-
ulometry and, if required, adjust the grinding
adjustment disk. If the coffee comes out of the
machine very quickly, it means that 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 com-
pacting, the espresso machine settings and the
cleaning of the filters.
