7.1.14 Only remove the portafilter once the grinding process has
been completed. Repeat approximately twice in order to fill the
grinder casing with the re-adjusted ground coffee.
7.2 Taking off the grinder cover
Grind or take out all coffee bean residues. Switch off the grinder
and pull the main plug. Turn both grind adjustment rings to coarse
and fix the brakes. Loosen the lock screw in the front with the allen
screw driver size 2mm. Carefully lift the grinder cover upwards.
7.3 Basic Adjustment of The Interior Grinders
The basic adjustment to a moderately fine setting has been carried
out in the factory using espresso beans. The following markings
have been made on the grinding mechanism (interior):
Red mark 1: Basic adjustment 0, finest setting and minimum grind-
ing disc spacing
Red mark 2: Basic factory setting and also the position for install-
ing and removing the lid, in order to achieve the finest setting after
positioning the lid.
7.1.6 Insert the adjusting handle (service tool) into the filler shaft.
The adjusting handle must engage in the slot into filler shaft’s
transverse bar.
7.1.7 Hold the adjusting handle firmly and push the portafilter into
the portafilter mounting until the grinder switches on.
7.1.8 Whilst the grinder is running, turn the adjusting handle clock-
wise until a slight ringing sound becomes audible. Now turn the
adjusting handle slightly anti-clockwise until no further ringing
sound can be heard.
It is important to ensure that no grinding disk
„rattling“ can be heard at the finest setting!
Otherwise the service life of the discs will be
significantly reduced.
7.1.9 Tighten the adjusting screws and remove the adjusting han-
dle from the filler shaft.
7.1.10 Insert the sealing ring again. If the sealing ring is damaged it
must be replaced.
7.1.11 Replace the hopper and allow it to engage in the bayonet
and replace the lock screw. Open the hopper slide.
7.1.12 Reset the desired grinding fineness.
7.1.13 Push your espresso machine’s portafilter into the portafilter
mounting (pos. 11/12) until the grinding process is switched on.
