Usage recommendations

Use freshly roasted whole beans for best flavour extraction, adjust the grind size incrementally to match your brewer and dose, and perform periodic cleaning of the burrs and hopper to prevent buildup. For espresso, test small adjustments until the extraction time and crema meet your machine’s requirements. Always follow safety instructions in the user manual when servicing the unit.
