Grinder calibration (adjustment)
Calibration of the grinder (with the adjusting knob) makes the fineness of the ground coffee
correspond with the fineness set on the scale (marked).
Calibration of the grinder must only be performed by persons familiar with the
unit after carefully reading the following instructions.
The basic calibration
according to 3.3.1
should be made:
- after replacing the grinding discs
- following inadvertent displacement of the basic
calibration
Change of scale setting as 3.3.2 should be performed:
- if the desired grinding fineness does not
correspond with the scale (adjusting knob)
- if an individual setting of the grinding fineness is
desired (customer setting)
Periodic checking of the grinding quality and grinding discs must only be
performed by competent specialists and/or service personnel.
