Operating principle / Differences between models
All the grinder models described in these original instructions are shop grinders (see chapter on “Intended use”).
The 1203 and 1403 model series differ in their grinding capacity and their type
of power supply (see chapter on “Technical data”).
Bag clamping and grinding are carried out separately and started manually in models with the prefix KR. These models are equipped with a bag shaking unit.
The bag is clamped and grinding started automatically in one process in models with the prefix KFA. These models are not equipped with a bag shaking unit.
