FRITSCH PULVERISETTE 23 - Manual (Page 12)

DANGER!
Explosion hazard!
– When grinding oxidizable substances, e.g. metals or
coal, there is a risk of spontaneous combustion (dust
explosion) if the share of fine particles exceeds a cer-
tain percentage. When grinding these kinds of sub-
stances, special safety measures must be taken and the
work must be supervised from a specialist.
– The high-speed rotor mill is not explosion protected
and is not designed to grind explosive materials.
n Do not remove the information signs.
NOTICE!
Immediately replace damaged or illegible information signs.
n Unauthorised alteration of the PULVERISETTE 23 will void Fritsch's
declaration of conformity to European directives and void the guar-
antee.
n Only use the PULVERISETTE 23 when it is in proper working order, as
intended and in a safety- and hazard-conscious manner adhering to
the operating manual. In particular, immediately rectify any malfunc-
tions that could pose a safety hazard.
n If, after reading the operating manual, there are still questions or
problems, please do not hesitate to contact our specialised per-
sonnel.
2.6 Hazardous points
n Because the grinding container operates uncovered for better heat
conduction, touching the grinding bowl or the fixture during the
grinding process results in a risk of impact. Bear this in mind in par-
ticular when starting the operation. Always turn the main switch to
"Off" before working on the grinding bowl clamp to prevent the start
button from being unintentionally activated.
n Crushing hazard when clamping the grinding bowl.
2.7 Electrical safety
2.7.1 General information
