5.2.7 Now brew a test portion of espresso using your machine. If the
result is unsatisfactory, alter the adjustment again by varying the
grinding time and grinding fi neness until the best coffee results
have been achieved.

If the grinding process is interrupted before the set grinding time
has expired, the LED in the active pre-selection button fl ashes. The
grinding process can be re-started by pushing the port-a-fi lter back

Test runs have proved grind adjustments 1 – 4
to be the most common settings for espresso
depending on the origin, roast and blend. This
should be taken into account when adjusting
the grinder for the fi rst time.
5.2.4 For the fi rst test run the grinding time settings are pre-pro-
grammed for single shots to 2.0 sec and for double shots 4.0 sec.
For changing these settings please see chapter 5.3.
5.2.5 Choose the single or double pre-select-button according to
your portafi lter. The LED shows which button is selected.
Single espresso left grinder
Single espresso right grinder
Double espresso left grinder
Double espresso right grinder
5.2.6 Push your espresso machine’s portafi lter into the partafi lter
mounting (pos. 11/12) so that the grinding process starts.
The fi rst operation will not result in the desired
amount of espresso because the grinder has
to fi ll up with ground coffee. The second shot
should give the correct result.
