harmful reected beams, care should be taken to keep anyone without protective eyewear from observing the
machine during operation. EVEN WITH protective eyewear, do not stare or allow others to stare continuously
at the laser beam during operation.
• DO NOT leave potentially combustible, ammable, explosive, or corrosive materials nearby where they could be
exposed to the direct or reected 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 as described in the Material Safety Instructions section of this manual. The laser
settings and engraving process must be properly adjusted for specic materials.
• Ensure the area is kept free of airborne pollutants, as these might pose a similar risk of reection, combustion,
etc.
• NEVER use this marking machine with the ber source’s housing opened, as the closed laser light path is
necessary to prevent laser radiation leakage.
• DO NOT modify or disassemble the laser and do not use the laser if it has been modied or disassembled by
anyone except trained and skilled professionals. Dangerous radiation exposure and other injury may result from
the use of adjusted, modied, or otherwise incompatible equipment.
2.4 Electrical Safety Instructions
• ONLY use this machine with a compatible and stable power supply with less than 5% uctuation in its voltage.
• DO NOT connect other machines to the same fuse, as the laser system will require its full
amperage.
• DO NOT use with standard extension cords or power strips. Use ONLY surge protectors rated
over 2000J.
• ONLY turn on the power to this machine when it is well grounded, either via a rm connection to a 3-prong
outlet or via the dedicated grounding cable rmly connected to the slot on the back of the main tower. For details
on grounding, see Electrical Grounding (Page 11).
• Turn the machine on and o using its power buttons in the correct order. The laser has a separate power supply
that is separately grounded. Pushing all the buttons at once, too quickly, or in the wrong order may send electrical
current to an ungrounded component, causing short circuits and other electrical hazards.
• ONLY use this machine with one hand at a time. The laser is powered by an extremely high voltage connection
and placing two hands on the machine at one time during operation has the potential to create a closed circuit
with the human body, resulting in electrical shock.
• The area around this laser marking machine should be kept dry, well ventilated, and environmentally controlled
to keep the ambient temperature between 32–104°F (0–40°C). The ambient humidity should not exceed 70%.
• Adjustment, maintenance, and repair of the electrical components of this machine must be done ONLY by
trained and skilled professionals to avoid res 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 specied, ONLY undertake adjustment, maintenance, and repair of the machine when it is
turned o and disconnected from its power supply.
