● Check the air filters and the sealing of the heating lamps regularly. ● Use HP-certified and HP-branded material and agents only. Do not use unauthorized third-party material or third-party agents. ● HP recommends the use of HP accessories for retrieving 3D parts and refilling the build chamber. If other methods are used, read the following notes: - Dust clouds generated during handling and/or storage can form explosive mixtures with air. Dust explosion characteristics vary with the particle size, particle shape, moisture content, contaminants, and other variables. - Check that the printer is properly grounded and installed to satisfy electrical classification requirements. As with any dry material, pouring this material or allowing it to fall freely or be conveyed through chutes or pipes can accumulate and generate electrostatic sparks, potentially causing ignition of the material itself, or of any flammable materials which may come into contact with the material or its container. ● Material storage, handling, and disposal as per local laws. See the Safety Data Sheets at http://www.hp.com/go/msds for adequate handling and storage. Follow your Environmental, Health, and Safety processes and procedures. ● Do not place the printer in a hazardous location area, and keep it separated from other equipment that could create a combustible dust cloud during its operation. ● Auxiliary post-processing equipment, such as for bead blasting, must be suitable for combustible dust. ● Stop operation immediately if sparks or material spillages are seen, and call your support representative before continuing. ● All personnel, when handling combustible dust, should be freed from static electricity by using conductive or dissipative footwear and clothing, and a conductive floor. Electrical shock hazard WARNING! The internal circuits inside the e-cabinet, and the heating and fusing lamps, operate at hazardous voltages capable of causing death or serious personal injury. Turn off the printer using the branch circuit breakers located in the building's Power Distribution Unit (PDU) before servicing. The printer must be connected to earth at mains outlets only. To avoid the risk of electric shock: ● Do not attempt to dismantle the internal circuit enclosures, heating or fusing lamps, or e-cabinet except during hardware maintenance tasks. In that case, follow the instructions strictly. ● Do not remove or open any other closed system covers or plugs. ● Do not insert objects through slots in the printer. NOTE: A blown fuse may indicate malfunctioning electrical circuits within the system. Call your support representative (see When you need help on page 163), and do not attempt to replace the fuse yourself. Heat hazard Electrical shock hazard 7

To avoid the risk of electric shock:
●
Do not attempt to dismantle the internal circuit enclosures, heating or fusing lamps, or e-cabinet except
during hardware maintenance tasks. In that case, follow the instructions strictly.
●
Do not remove or open any other closed system covers or plugs.
●
Do not insert objects through slots in the printer.
NOTE:
A blown fuse may indicate malfunctioning electrical circuits within the system. Call your support
representative (see
