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 J made so that the scraper and mortar fit together exactly For this reason only use mortars pestles and scrapers together that match 1 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 D To open the bayonet rotate the mortar to the left d J To close the bayonet rotate the mortar to the right 1 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 23 FRITSCH aa Note 4 i E N W Rotation to the right clockwise
