Hazard and Warning Information
General Information
► If the device is not used in compliance with the supplied instructions, the safety of the device can
no longer be guaranteed.
► The device may only be operated using a mains cable with the country-specific plug system. Any
necessary alterations must be carried out by a qualified electrician.
► The device may only be operated if the information on the identification plate conforms to the
specifications of your local mains power supply.
► The device may only be plugged into outlets which are connected to the protective conductor
system.
► The mains plug must be easily accessible.
► Disconnect the device from the mains before carrying out work on the electrical parts.
► Check connection cables (such as power supply cords), tubes and housing (i.e. the key-pad)
regularly for damage (i.e. kinks, cracks and porosity) or signs of ageing. Devices with damaged
connection cables, tubes or housing parts or other defects must not be operated!
► Defective devices must be put out of service immediately. Remove the mains plug and ensure the
device is not used. Send the device for repair!
► Only operate the device under supervision.
► Observe the accident prevention regulations by the trade association!
► It is the responsibility of the operator that national regulations during operation and regarding a
repeated safety inspection of electrical equipment are complied with. For Germany these are the
regulation 3 by DGUV (German Statutory Accident Insurance) in relation with VDE 0701-0702 (As-
sociation for Electrical, Electronic and Information Technologies).
► Information on REACH and SVHC is available on our website www.renfert.com, in the Support area.
Specific Information
► The German ordinance on hazardous substances ("GefStoffV") or equivalent national regulations
must be observed during operation, cleaning, and maintenance.
► The power socket on the device may only be used for the purpose specified in the instructions for
use. The connection of other electronic devices could lead to material damage.
► Before connecting an electronic device to the power socket, ensure that the electronic device is
first switched off.
► Read the operating instructions of the other appliance and comply with the safety instructions
contained in the document.
► Please observe the national regulations and permitted exposure to dust in a working environment.
Please ask the "National Institute for Occupational Safety and Health" or other responsible au-
thority.
► Please observe the Safety Data Sheets of the materials to be extracted.
► Always wear protective gear, when extracting hazardous materials.
► It is necessary to wear suitable personal protective equipment when emptying the dust drawer or
cleaning, depending on the type of extracted material.
► When disposing of the extracted material or used filter, please observe the local specifications
and accident prevention regulations!
► Make sure the dust drawer is fully closed during operation.
► Do not operate without a suction hose.
► Do not extract flammable or explosive gasses, fumes or dust.
► The following applications involve increased risks and are therefore not permitted:
When cleaning milling chambers and SLM printing systems by suction, a sufficiently high con-
centration and purity (i.e. unmixed with other dental dusts such as gypsum, resins) can result
in spontaneous ignition or the milling dust exploding or printing powder because of a potential
exothermic reaction (e.g. due to oxidation).
An alternative cleaning method must be selected for the following milling or printing media in
particular (such as 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.
