FRITSCH PULVERISETTE 2 - Manual (Page 22)

NOTICE!
If liquid nitrogen is added to the grinding process, it is only
permitted with the monolithic stainless-steel grinding set.
With mineral materials, there is a great risk of damaging
the grinding elements by adding liquid nitrogen.
Grinding with mineral grinding elements and added liquid
nitrogen will void the guarantee.
6.3 Installing / removing the grinding set
The grinding parts used in the laboratory mortar mill are
made so that the scraper and mortar fit together exactly.
For this reason, only use mortars, pestles and scrapers
together that match.
Because grinding parts wear faster or slower depending on the load, it
may be necessary to readjust the scraper and pestle.
When the lid of the mill is open, it is easy to access the grinding parts.
6.3.1 Installing/removing the mortar
CAUTION!
Crushing hazard!
When inserting the mortar!
The mortar is fastened to the carrier with a bayonet catch.
To open the bayonet, rotate the mortar to the left.
To close the bayonet, rotate the mortar to the right.
When the bayonet is open, it is possible to lift the mortar out of the mill.
When inserted, the mortar is installed onto the centre of the support.
Rotate the mortar until the bayonet locks into place. When the bayonet
has locked into place (the mortar no longer wobbles), turn the mortar to
the right to close the bayonet.
