IMPELLER
It is possible to change the dosage
quantity by raising or lowering the
height of the impeller.
Proceed as following:
• remove the tamper window
loosening the screws;
• loosen the set screw in the collar of the
tamper shaft coupling.
• holding the tamper shaft coupling in
place, rotate the impeller in the direc-
tion desired. To increase the dosage
amount, turn the impeller clockwise,
as viewed from below. To decrease the
dosage amount, turn the impeller
counter-clockwise, as viewed from
below. Approximately, one 360° turn is
equivalent to 1 gram of coffee.
• ensure that the set screw is against the
flat side of the tamper shaft. Re-
tighten the set screw in the collar of
the tamper shaft coupling.
Finer adjustment of the dose can be
given by moving the
