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.
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".
The inner funnel can be removed for cleaning and the outer funnel can
be unscrewed.
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. For this reason, wear gloves that are safe and
without defect.
