2. Adjustable Burr Grinder with Memory Setting Equipped with a 15-level conical burr grinder for precise grinding. The grind quantity can be customized and saved via combination keys (see user manual). To reset continuous grinding protection, press the handle once and rotate the brewing lever once.

3. Patented Smart-Tamping System Our patented all-in-one tamping design minimizes mess and extra steps. For optimal tamping results, use the correct filter basket and ensure proper dose amount. Under-dosing may result in low pressure; over-dosing may make the portafilter difficult to lock or cause excessive pressure during extraction.

4. Extraction & Pressure Guidance It’s normal for the portafilter to feel tight during the first few uses; it will loosen slightly over time, ensuring a durable seal. No pressure may result from under-dosing or coarse grind; excessive pressure may come from over-dosing or overly fine grind. Adjust accordingly to maintain stable extraction around 9 bar.

5. Golden Extraction Example For medium-dark roasted beans, use the double-shot basket, set a mid grind level, double-tap the grind button within 1.5 seconds (for a double dose), then start extraction. The ideal pressure range is 5–12 bar. Adjust grind size or coffee dose to maintain around 9 bar for the best espresso balance.

6. Dual Pump & Dual Heating System The dual-pump dual-heating design enables rapid preheating and simultaneous espresso extraction and milk frothing. For optimal results, release a small amount of hot water before brewing to preheat the cup and flush excess water from the system.
