SOLIS CAFFESPRESSO PRO Mode D'emploi page 75

Press down with approx. 15–20 kg of pressure and repeat the tamping several times.
Applying consistent pressure is more vital than applying extremely high pressure.
After tamping, you might need to add some more coffee grounds and tamp again to
ensure there is enough coffee grounds in the filter basket for the coffee you desire.
Tip: After tamping, the coffee grounds should be level with the edge of the filter
basket. When pressing the tamper on top, the upper edge of the tamper and the
filter basket rim should align.
NOTE: When using finely ground coffee for the single wall filter basket, you might
need to use more coffee than usual to achieve the right amount.
– After tamping, remove any coffee residue from the rim of the filter basket so that
it can be inserted into the group head properly.
