6.5 Clamping the grinding bowls
6.5.1 Clamping with the "Safe-Lock" (5) tensioning device
Fritsch GmbH confirms that each Safe‐Lock clamping system
is produced and tested according to our internal quality
standards without any exception. Fritsch GmbH measures
the tension force of each individual Safe‐Lock ‐ clamping
system. The tension force must be in the range 11.2 –
11.3kN +/‐ 0.2kN to pass our Quality Control.
Carry out the following checks for every grinding before clamping the
grinding bowls:
n Has the rubber disc been inserted in the grinding bowl holder? The
rough side should be facing upwards!
n Check the rubber disc in the grinding bowl holder for damage:
Replace the rubber disc if it has been pressed flat!
n The Teflon flat seal (for the sealing between lid and bowl) may not
be damaged or soiled.
Replace heavily deformed Teflon flat seals.
n The surfaces of the lids and bowls on which the Teflon flat seals lie
must be clean!
n Check the rubber disc of the pressure piece for damage!
Replace rubber discs that have been pressed flat and are protruding
laterally from the pressure piece.
