Ensure that this manual and the software manual are both included with this device if it is
ever given or sold to a third party.
•
DO NOT
operate this device continuously for more than 5 hours.
Stop every 5 hours for at least ½ hour.
•DO NOT
leave this device unattended during operation. Observe the
device throughout operation and, if anything seems to be operating

department's phone number is clearly displayed nearby. In the case of a
fire, cut electrical power before dousing the flame. Familiarize yourself
with the correct range for your extinguisher before use. Take care not to
use your extinguisher too close to the flame, as its high pressure can
produce blowback.

Laser Safety Instructions
This machine uses an invisible CLASS 4 LASER, the strongest and most dangerous class of
laser available for public use. Used without care, it can cause serious property damage and
personal injury including but not limited to the following:
As such,
•NEVER interfere with the laser beam.
•DO NOT place any part of your body under the laser lens during operation. Take
measures to protect yourself from potentially reflected laser beams including the use
•NEVER attempt to view the laser directly without protective eyewear. Always wear safety
goggles or glasses designed to filter the specific wavelength of your engraver's laser with an
optical density (OD) of 5+. As even seemingly matte materials can produce harmful reflected
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, 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 as 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 airborne pollutants, as these might pose a similar risk of
reflection, combustion, etc.
•NEVER use this marking machine with the fiber 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 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.
•The laser will easily burn nearby combustible materials
•Some working materials may produce radiation or harmful gasses
during processing
•Direct exposure to the laser will cause bodily harm including serious
burns and irreparable eye damage

Electrical Safety Instructions
•ONLY use this device with a compatible and stable power supply with less than 5%
fluctuation in its voltage.
⚫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 back of the main tower. Do not use with an ungrounded 3 to 2 prong
adapters. 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, galvo, 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°F (5–35°C).
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.
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.
