Group and piston.
These are made of plastic resins and are the elements where the
machine makes the infusion with the dosage of ground coffee.
The group has moving parts activated by 24 Vdc motor that rotates the flywheel that moves
the coffee holder from the dosage device to the piston. It also moves a lever that acts on a
micro switch, which indicates the position that the group is located to the electronic board.
At rest position, the group cannot be removed. Before removing, and with the machine
switched on, activate the black button on the device. On pressing button, the group situates
itself in the load coffee position. Now the levers that hold it in place can be turned to free it
from the support and it can be removed.

To replace the group in the machine, it can be in any position and it does not matter if it has
been turned while it was out of the machine. It is only necessary to fit it and fasten the holding
levers; the motor of the group will automatically position it correctly.
