1 Safety Information
• Ensure the area is kept free of airborne pollutants, as these might pose a similar risk of
reflection, combustion, etc.
• NEVER use this marking machine with the fiber source's housing open, 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 modified or
disassembled by anyone except trained and skilled professionals. Dangerous radiation exposure
and other injury may result from the use of adjusted, modified, or otherwise incompatible
equipment.
1.5 Electrical Safety Instructions
• ONLY use this device with a compatible and stable power supply with less than 5% fluctuation in
its voltage.
• DO NOT connect other devices 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 device when it is well grounded, either via a firm connection
to a 3-prong outlet or via a dedicated ground cable firmly connected to the proper slot on the
back of the main tower. 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.
• Turn the device on and off using its key and power buttons in the correct order. The
mainboard, galvanometer, and laser have separate power supplies that are grounded
in order. Activating everything 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 device 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 device should be kept dry, well ventilated, and
environmentally controlled to keep the ambient temperature between 40 ℉ –95 ℉ (5 ℃ –35 ℃ ).
The ambient humidity should not exceed 70%.
• 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 and disconnected from its power supply.
