4.4.5. Replacing a grinder
Removing the grinder
• The grinding mechanism of the grinding
unit cannot be replaced as the grinding
ring and grinding cone are adapted to each
other. The entire grinding unit must
therefore be replaced.
• Replace the grinding unit if the grinding
mechanism has become blunt.
- To replace the grinding unit for
maintenance, see Chapter 8.3.
