DANGER!
Explosion hazard!
– Wear safety goggles. The high temperature or chemical
reactions during the grinding process may result in
overpressure in the grinding bowl. Splashing hazard!
Explosion hazard! Do not fail to observe Ä Chapter 5.1
‘Safety information’ on page 27 and Ä Chapter 5.8.2
‘Safety measures against an excessively high pressure’
– Never use brute force to open the grinding bowl. Open
the grinding bowl only if you are sure that the internal
pressure has been released completely. Observe the
opening instructions in Ä Chapter 5.9.2 ‘Opening the
grinding bowl after a grinding operation’ on page 41
and Ä Chapter 5.8.2 ‘Safety measures against an
excessively high pressure’ on page 40.
– The device may only be operated indoors. The sur-
rounding air must not contain any electrically conduc-
tive dust.
– When grinding oxidisable substances (e.g. metal or
coal), there is a risk of spontaneous combustion (dust
explosion) if the proportion of fine particles exceeds a
certain percentage. Chemical reactions are also pos-
sible during wet grinding. When grinding these kinds of
substances, special safety measures (e.g. wet grinding)
must be taken and the work must be supervised by a
specialist.
– The device is not explosion-protected and is not suit-
able for grinding explosive materials.
DANGER!
– Do not reuse damaged accessories.
– If the planetary micro mill or its components are dam-
aged or if its operation is not as described in the oper-
ating manual, the device may not be put into service. In
such a case, consult your Fritsch GmbH representative
or distributor.
WARNING!
The maximum accepted concentration (MAC) levels of the
valid safety regulations must be observed. If necessary,
ventilation must be provided or the machine must be oper-
ated under an extractor hood.
