2.5.2 Specific information
► The German ordinance on hazardous substances ("GefStoffV") or equivalent national regulations
must be observed during operation, cleaning, and maintenance.
► The mains socket on the device is only designed for purposes specified in the operating instruc-
tions. Connecting other devices may cause material damage.
► Switch off the electrical device before connecting an electrical appliance to the appliance outlet.
► Read the operating instructions for the electrical appliance which is to be connected and observe
the stipulated safety instructions.
► Observe national regulations and permitted dust exposure levels in the working environment. Re-
fer to your national association for occupational safety and health or the responsible authority.
► Please observe the Safety Data Sheets of the materials to be extracted.
► Wear personal protective equipment when suctioning hazardous materials.
► Depending on the type of extracted material, wear appropriate personal protective equipment
when emptying the dust drawer or cleaning.
► When disposing of the extracted material or used filters, observe local provisions and accident
prevention regulations!
► Suctioning may only be performed with the dust drawer closed.
► Do not operate without a suction hose.
► Do not extract flammable or explosive gasses, fumes or dust.
► The following applications are associated with increased risks and are therefore not permitted:
When cleaning milling chambers and SLM printing systems by suction, a sufficiently high
concentration and purity (i.e., unmixed with other dental dusts such as plaster, resin) can result in
spontaneous combustion or the milling dust or printing powder exploding because of a potential
exothermic reaction (e.g., due to oxidation).
An alternative cleaning method must be selected, particularly for the following milling or printing
media (e.g., manual cleaning):
• Wood
• Titanium / titanium-aluminum
• Light metals and light metal alloys (e.g., aluminum, magnesium)
• Cobalt-chrome powder (e.g., for use in SLM systems)
If large quantities of light metals such as titanium alloy are processed (e.g., with sandpaper), pro-
ducing very fine grinding dust, a sufficiently high concentration and purity may result in sponta-
neous combustion because of a potential exothermic reaction.
► Do not suction hot materials.
► Do not suction liquids.
► If the dust extractor is employed to extract hazardous materials, appropriate personal protective
gear must be worn and steps must be taken to ensure that the exhaust air is properly ventilated.
Refer to the safety data sheets for the corresponding requirements.
► Dispose of extracted material in accordance with statutory regulations.
