Press down on the burr lock pin, under the round, flat grinder adjustment wheel that rests at the juncture between the glass or plastic hopper and the grinder mechanism. Typically this is the most narrow portion of the machine.
Keep pressing on the collar pin, and simultaneously turn the collar, moving it between the grind setting steps. There is a click on some models when you hit a new grind level, while on others, there are numbers printed on the collar to identify the grind.
Create the coarsest or most fine bean grind by turning the collar fully in one direction or the other.
Refine the basic grind consistency further by testing beans through the grinder at different settings. Some Faema models neither click between collar settings nor have printed grind guide numbers, so small increment adjustments of the collar and testing the results is the only way to find your preferred grind setting.
Release the burr lock pin to fix the grinder wheel in place.
- Length of grinding time is as important to coffee grinding as the burr setting. If your coffee grind is coming out of the machine coarser than you wish, you are likely processing the beans for too short a period. If it is too finely ground, you are processing it too long.
