The coffee grinder is a new design and the ground coffee dose is
determined via software setting and by means of a sensor that counts
the number of revolutions of the grinding wheels (see view below).
Therefore, it is very important that the mechanical adjustments to the
grade of grinding be checked very frequently. In order to get a dose of
7 grams of coffee a certain number of revolutions is counted; by
increasing or decreasing such value the amount increases or decreases.
It is therefore possible to set selections with different coffee doses.
It is therefore clear that it is very important to keep the adjustment of
the grinding wheels constant to obtain accurate coffee doses.
Especially in the first period of use (1000-2000 selections), because of
the greater wear due to the initial settling.
The adjustment can be performed also approximately by regularly
checking the weight of the ground coffee and its grade of grinding.
The motor winding is fitted with a self-reset overheating protection.
Flat-type grinding wheels are used.
For further information refer to the specific manual.
