3.4.10 Adjusting the grinding unit
Dependent on the roasting degree and on the oil rate of the used
coffee beans the grinder setting must be changed
►
Bright roasting, low oil rate
►
Dark roasting, high oil rate
The correct grinding unit adjustment is crucial for the coffee taste, the
strength and the flavour of the coffee.
Note:
A very fine grinding unit setting in combination with a very high
amount of ground coffee can cause malfunctions especially by using
dark roasted coffee beans with high oil rate.
Warning:
Adjust the grinding unit only while the grinding
unit is running! Otherwise the appliance may be
damaged.
The new setting will not become apparent until the second or third cup
of coffee.
