We recommend that you also readjust the grinder after:
– a change of sort of coffee beans
– extreme changes of the degree of grinding

7. Adjusting the grinder
You have the opportunity of adapting the grinder to the roast of
your coffee. We recommend the following:
for a light roast
a finer adjustment
for a dark roast
a coarser adjustment
To adjust the grinding, turn the setting rings into the required
position (Fig. 2)
You have the following options:
the smaller the dots, the finer the grinding
the larger the dots, the coarser the grinding
The grinding may only be adjusted with the grinder in
operation.
8. Adjustment of water hardness
Water is heated in the machine. This leads to scale as a result of
use, which is automatically shown on the display. The machine
must be adjusted to match the hardness of the water used. For this,
please use the enclosed test stick.
1° water hardness on the German scale corresponds to 1.79°
on the French scale.
The machine has 5 hardness settings to choose from. The indica-
tions on the display mean:
