Fig. 14:
The display (F1) shows 00.0. The current gap width and the display therefore
match.
The wear of the breaking jaws is not recorded by the gap width measurement. For
this reason the alignment of the gap width should be performed regularly in order
to guarantee matching between the information in the display and actual gap width.
The greater the load on the BB 50 and the harder and more abrasive the grinding
material, the more frequently a zero point alignment to compensate for wear is
required.
The reading in the display will otherwise not correspond to the actual gap width.

Before starting the machine, do not put any grinding material in the grinding
chamber or fill hopper. This can lead to a blockage and cause damage to
mechanical components.

in a clockwise direction.
• You can increase the gap width (sw) with a twist of the hand wheel (D)
in an anti-clockwise direction
