7 Cleaning
DANGER!
Mains voltage!
– Before beginning with cleaning work, disconnect the
mains plug and protect the device against being unin-
tentionally switched back on!
– Do not allow any liquids to flow into the device.
– Indicate cleaning work with warning signs.
– Put safety equipment back into operation after
cleaning work.
NOTICE!
Grinding stock residues on the edge destroy the lip seal
over time!
NOTICE!
Grinding sets made of agate contain water of crystallisation
and must therefore not be dried in the microwave. In addi-
tion, the bowls must not be exposed to large temperature
fluctuations, otherwise they will be damaged.
The mortar mill can be wiped with a damp cloth when it is switched off.
The mortar and the pestle can be taken out of the device for cleaning
(see Ä Chapter 6.3.1 ‘Installing/removing the mortar’ on page 22).
7.1 Lid seal
9 Seal
The seal (9) in the lid separates the working chamber from the rest of the
machine. The seal is simply clamped in a U-channel and can be removed!
NOTICE!
When grinding a sample which produces excessive dust or
is projected from the mortar during grinding, it is necessary
to use the seal to avoid unnecessary contamination or
damage. The seal is not required for grinding stocks which
remain in the mortar (e.g. pastes).
