2.4 Electrical Safety Instructions

• ONLY use this device with a compatible and stable power supply with less than 5% fluctuation in its voltage.
• DO NOT plug the engraver and chiller into the same circuit or connect other devices to same
circuits that they will use, as this laser system is extremely powerful and will require its full
amperage. If no other devices are on the same circuits, the laser and chiller can work on
standard 20A 110V circuits, and the external fan can be plugged into the engraver or use the
same circuit as the water chiller. If it is necessary to run the laser, the water chiller, and the
external fan all on the same circuit, its wiring will need to be specially prepared to handle at
least 35A of current at 110V.
• DO NOT use with standard surge protectors, extension cords, or power strips. Only use additional wiring thick
enough to safely handle the full load of the machine.
• ONLY turn on the power to this device when it is well grounded, either via a firm connection to a 3-prong outlet or
via a dedicated grounding cable firmly connected to the proper slot on the cabinet. Do not use with an ungrounded
3 to 2 prong adapter. The device's grounding should be checked regularly for any damage to the line or loose
connections.
• The area around this laser engraving device should be kept dry, well ventilated, and environmentally controlled to
keep the ambient temperature between 40–95°F (5–35°C). For best results, keep the temperature at 75°F (25°C) or
below. The ambient humidity should remain between 5–90%.
• DO NOT drain or fill the integrated water tank while it is connected to its power supply. Disconnect the chiller
and the laser from power before adjusting the cooling liquid level. Do not allow any electronic component to
become wet and, if any accidentally does become wet, leave the entire system disconnected from power until all
components are fully dry.
• Adjustment, maintenance, and repair of the electrical components of this device must be done ONLY by trained
and skilled professionals to avoid fires and other malfunctions, including potential radiation exposure from damage
to the laser components. Because specialized techniques are required for testing the electrical components of this
marking system, it is recommended such testing only be done by the manufacturer, seller, or repair service.
• Unless otherwise specified, ONLY undertake adjustment, maintenance, and repair of the device when it is turned
off, disconnected from its power supply, and fully cooled. For maximum safety, wait about 3 minutes after turning
the machine off before adjusting the integrated chiller or other electronic parts. This will allow time for the ground
connection to clear any residual charge.

2.5 Material Safety Instructions

• Users of this laser engraving machine are responsible for confirming that materials to be processed can withstand
the heat of the laser and will not produce any emissions or byproducts either harmful to people nearby or in
violation of local or national laws or regulations. In particular, do not use this device to process polyvinyl chloride
(PVC), teflon, or other halogen containing materials under any circumstances.
• Users of this laser engraver are responsible for ensuring that every person present during operation has sufficient
PPE to avoid the injury from the emissions and byproducts of the materials being processed. In addition to the
protective laser eyewear described above, this may require goggles, masks or respirators, gloves, and other
protective outer clothing. Always wear hand protection when working with metal to avoid cuts and burns.
• DO NOT ever under ANY circumstances use this laser engraver if the exhaust system is not working properly.
Always ensure that the exhaust fan can remove the dust and gas produced by the engraving process in accordance
with all applicable local and national laws and regulations. Immediately stop use if the exhaust fan or vent pipe
malfunctions. Periodically check the air assist intake filter to ensure it stays free of any dust or debris.
