- Insert Portafilter: Attach the portafilter to the brew head of the machine by aligning it and twisting it firmly to the right until it locks into place.
- Place Cup: Position your espresso cup(s) on the drip tray directly under the portafilter spouts.
- Select Shot Size: Press the '1' button for a single shot or the '2' button for a double shot. The machine will automatically brew the pre-programmed volume.
