DANGER!
Mains voltage!
– Before beginning with cleaning work, disconnect the
mains plug and protect the device against being unin-
tentionally switched back on!

– Indicate cleaning work with warning signs.
– Put safety equipment back into operation after

NOTICE!
Cool grinding elements made of zirconium oxide slowly and
carefully.
They must never be exposed to thermal shocks as this
could cause irreparable damage to the parts ® They will
burst apart with powerful force.
The seal ring has to be removed before sterilisation.
7.1 Grinding elements
n Clean the grinding bowl and grinding balls each time after using
them:
Clean them, e.g., under running water using a brush and a commer-
cially available cleaning agent. It is recommended to use a wire
basket or sieve with a narrow mesh width for small grinding balls.
n Take particular care to thoroughly dry tempered steel bowls and
grinding balls with a towel after cleaning; otherwise there is a risk of
corrosion.
n Cleaning with an ultrasonic cleaner is permitted.
n Only heat the drying cabinet up to 100 °C for sterilisation.
7.2 Mill
n The mini-mill can be wiped down with a damp cloth when the main
switch is switched off. When the main switch is switched on there is
a danger of unintended start up.
