1. Safety Information
•
DO NOT ever under ANY circumstances use this laser engraver if the water cooling system is
not working properly. Always activate the water cooling system and visually confirm that water
is flowing through the entire system before turning on the laser tube. Immediately stop use if
the water cooling system malfunctions.
•
DO NOT use generic antifreeze in your cooling water, as they may leave corrosive residues and
solidify inside your hoses and piping, causing malfunctions and even explosions. Use custom
laser-safe formulations or use and store your engraver in a climate-controlled area.
•
DO NOT leave potentially combustible, flammable, explosive, or corrosive materials nearby where
they could be exposed to the direct or reflected laser beam.
•
DO NOT use or leave sensitive EMI equipment nearby. Ensure the area around the laser is free of
strong electromagnetic interference during any use.
•
ONLY use this machine for working the materials described in the Material Safety section of
this manual. The laser settings and engraving process must be properly adjusted for specific
materials.
•
Ensure the area is kept free of other airborne pollutants, as these might pose a similar risk of
reflection, combustion, etc.
1.6 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
the 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
℉
(5–35
℃
). For
best results, keep the temperature at 75
℉
(25
℃
) or below. The ambient humidity should remain
between 5–90%.
