7.1.14 Only remove the portaﬁ lter once the grinding process has

been completed. Repeat approximately twice in order to ﬁ ll 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 ﬁ x 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 ﬁ ne 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, ﬁ nest 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 ﬁ nest setting after

positioning the lid.

7.1.6 Insert the adjusting handle (service tool) into the ﬁ ller shaft.

The adjusting handle must engage in the slot into ﬁ ller shaft’s

transverse bar.

7.1.7 Hold the adjusting handle ﬁ rmly and push the portaﬁ lter into

the portaﬁ lter 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 ﬁ nest setting!

Otherwise the service life of the discs will be

signiﬁ cantly reduced.

7.1.9 Tighten the adjusting screws and remove the adjusting handle

from the ﬁ ller 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 ﬁ neness.

7.1.13 Push your espresso machine’s portaﬁ lter into the portaﬁ lter

mounting (pos. 11/12) until the grinding process is switched on.
