Basic adjustment of the grinding finess

Grinding
The grinder adjustment can be easily reached through the space between the bean hoppers, before
adjusting loosen the fixation screw in front of the adjuster wheel to be able to rotate it.
To adjust the coarseness for left grinder, rotate the adjuster wheel towards you for coarser
grinding. For finer grinding rotate the wheel away from you.
To adjust the coarseness for right grinder, rotate the adjuster wheel towards you for finer grinding.
For coarser grinding rotate the wheel away from you.
Take into consideration that after the adjuster is moved, the effect is not immediate, it takes about
1 coffee cycle for the new coffee grounds to reach the outlet and into the brewer. So to test the
new adjustment, observe the second coffee after the change.
The finer the grinding, the slower the coffee will come out, and longer time will be needed for the
extraction of the espresso and vice versa.
