How do I adjust the grind size on the Esperto Caffe?

The grind setting can only be adjusted while the grinder is running — start brewing a coffee first, then turn the grind adjustment dial clockwise toward '+' for a coarser grind (faster flow) or counterclockwise toward '-' for a finer grind (slower, more aromatic flow). Only change the setting by small increments and observe the taste difference over 1–2 cups before adjusting again. The factory default is grind level 2.
