. ADJUSTMENT
. GRIND ADJUSTMENT SYSTEM
8.2.1 Rotate the grind regulator ( ) until
reaching the grind level desired.
Rotating the grind regulator clockwise will
result in a courser grind; turning the regulator
counterclockwise will result in a finer grinder
(Fig. 1).
Fig. 1
Only for a K6 model: Once you reach
the desired grinding point, you can fix the
grinding regulation using the regulation
brake ( ) (Fig. 2).
Fig. 2
NOTE: If the coee
throughput is very low, this
is because the coee is
being ground very fine. If
the throughput is very high,
this is because the coee is
being ground very coarse. A
perfect Espresso is produced
when the grinding gives an
infusion of 25 ml of coee in
25 seconds using about 7 g of
ground coee.
NOTE: It is recommended
that this operation be
performed, when changing
to a finer grinding, with the
motor running, to prevent
coee from building up
between the burrs and
blocking the grinder.

. CLEANING THE GRIND CHAMBER
It is recommended that the grind chamber
be cleaned monthly with a cleaner . This
process will eliminate smelly residues from
the coee remains, which can negatively
aect the quality of the brewed coee.
Care is needed when handling cutting burrs
during cleaning.
The steps to follow are:
• To properly clean the bean hopper
(), first empty out all remaining beans
and fragments.
• Close the bean trap on the hopper ( )
and grind out the remaining coee in the
grind chamber.
• Pour the recommended grinder cleaning
product into the bean hopper ( ) and
open the bean trap ( ), allowing the
