6.6.2 Inserting the grinding jar
Insert the grinding jar into the grinding jar holder as follows:
Place the grinding jar from above into the open grinding jar holder and press lightly into the
centering (8).
Turn the locking wheel (7) clockwise until the grinding jar is firmly seated in the grinding jar
holder.
Turn the locking pin (6) by about 60° so that it engages in one of the grooves.
Now tighten the locking wheel (7) again. If the grinding jar is clamped, loosen it slightly in an
anti-clockwise direction until the locking bolt (6) is firmly in place and cannot vibrate.
NOTE All grinding points must always be loaded. If fewer grinding jars are required, an empty
grinding jar (without grinding balls, without material to be ground) or an adapter must be used
as a counterweight. The grinding jar adapters are available as accessories (order number
03.018.0155).
Never operate the MM 400 without a grinding jar or adapter!
