To remove the AZK 30 group, in addition to the lower lever and the upper nut, release the bolt shown in
the image above.
AZK 10 - AZK 20. Washer position and coffee capacity
The piston features a spring and two washers, which adjust the
pressure of the piston on the ground coffee, depending on their
position.
We recommend fitting two washers in the correct position,
according to the amount of coffee dosed. Otherwise, the group
may be blocked by excess coffee.
The amount of coffee that the two pistons of the AZK10 and
AZK20 groups can compress is indicated in the table below,
according to the position of their washers.
