7 Cleaning
DANGER!
Mains voltage!
– Before beginning with cleaning work, unplug the mains
plug and protect the device against being unintention-
ally switched back on.
– Do not allow any liquids to flow into the device.
– Indicate cleaning work with warning signs.
7.1 Device
The outside of the device can be cleaned with a soft, damp cloth when it
is in the switched off state.
Do not use solvents for cleaning.
7.2 Grinding chamber
The type and frequency of thorough cleaning depends on source mate-
rial and its final fineness. We recommend regular checks at the beginning
in order to adjust the cleaning intervals for the use of the variable speed
rotor mill.
Residual source material beneath the labyrinth disk or in the area around
the motor mount must be carefully and completely vacuumed away - if
necessary, use a brush or vacuum cleaner brush for the final touch-up.
The collecting vessel, rotor, sieve and labyrinth disk should be thor-
oughly cleaned outside of the variable speed rotor mill - they may be
brushed off when wet or cleaned in the ultrasonic cleaner "LABORETTE
17".
Turn the inner funnel to lift it out for cleaning. Perform a turning motion
again to set it back in place.
When cleaning the grinding elements, make sure that all guiding surfaces
with gliding movements are cleaned. These surfaces can also be lightly
oiled.
Caution when cleaning the grinding elements:
The rotor and sheet metal parts such as sieves and the collecting vessel
can have sharp edges. Make sure to wear gloves that are safe and
without defect. Sieves with reinforced edges can be used to avoid the
cutting hazard from sieve rings. These do not have any sharp metal
edges.
