Operating Instructions
Brewing Espresso:

- Add the appropriate amount of finely ground coffee into the filter. For a single shot, use 7-8g; for a double shot, use 16-18g.
- Use the tamper end of the coffee spoon to firmly press down the coffee grounds. Ensure the edges of the filter are clean.
- Attach Portafilter: Insert the filter holder into the machine's brewing head. Turn it to the right until it locks securely into place.
- Place Cup(s): Position your espresso cup(s) on the drip tray directly beneath the filter holder's spouts. The machine features a cup warming grill on top to preheat your cups, ensuring your espresso stays warm longer.

- Froth Milk:
- Submerge the tip of the steam wand just below the surface of the milk.
- Angle the pitcher slightly to create a swirling motion.

Maintenance and Cleaning
Regular cleaning ensures the longevity and optimal performance of your espresso machine.
- Drip Tray: The detachable drip tray should be emptied and cleaned regularly. Simply slide it out, discard the liquid, and wash with warm, soapy water. Rinse thoroughly and dry before reinserting.

- Filter Holder and Filters: After each use, remove the filter holder and discard used coffee grounds. Wash the filter holder and the selected filter (single or double) with warm, soapy water. Use a brush to clean any stubborn residue from the filter holes.
- Steam Wand: As mentioned in the operating instructions, clean the steam wand immediately after each use to prevent milk buildup. If blockages occur, use a small needle or pin to clear the nozzle.
