PROGRAMMING

The 3 programmable buttons are used exclusively to set the grinding time in seconds (GbT models) or the weight setting in grams (GbW models).

Factory setting

T models: 1=4.3 sec / 2=5.6 sec / 3=7.0 sec

GRIND ADJUSTMENT

The adjustment (5) consists of a stepped macro (upper ring, distance 0.1mm) and a stepless micro adjustment (lower ring, distance 0.01mm).

Recommended settings

(dependent on roast/roast level)

Ristretto: Macro 4-8, Micro 1
Espresso: Macro 6-10, Micro 1
LonghI: macro 8-12, micro 1

NOTE: Adjustment of more than 1 step on the macro ring or more than 5 steps on the micro ring should only be executed while grinding

With the grinder running, turn the macro ring to the right for finer settings (FINE direction) or to the left for coarser settings (COARSE direction).
The pointer marks the selected setting
The stepless micro ring ranges from coarse (11) to fine (1) and may be used for fine tuning
Notch 1 on the macro ring serves as the zero point for the micro adjustment.

GRINDING PROCESS
