3.5.1 Basic adjustment
The coffee grinder is factory set for an average grind
fineness.
WARNING
• Keep your fingers away from the grinding
mechanism when the machine is in operation.
WARNING
• If there is a sound of two stones rubbing against
each other, make the grind coarser.
• The grinding disks must never come into contact
with one another.
• The grind fineness and grind capacity depends on
the type of coffee beans and the roasting.
• Always adjust the coffee grinder from coarse to fine
with the grinder running or empty. Adjusting from
fine to coarse can be done when the grinder is
stationary.
1. Close the bean canister plug.
2. Remove the stainless steel coffee guide [1].
3. Hold a beaker under the coffee grinder outlet and
run the grinder until it is empty.

that a 0.35 mm feeler gauge fits between them.
7. After adjusting the grind fineness, carefully check
the operation of the brewer, see Section 2.4.3
Adjust the grind fineness as necessary!
