This manual is the designated user guide for the installation, setup, safe operation, and maintenance of your cabinet
laser engraver. It is divided into six chapters covering general information, safety instructions, installation steps,
operation instructions, maintenance procedures, and contact information.
ALL personnel involved in the installation, setup, operation, maintenance, and repair of this machine should read
and understand this manual, particularly its safety instructions. Some components are extremely high voltage
and/or produce powerful laser radiation. Substandard performance and longevity, property damage, and personal
injury may result from not knowing and following these instructions.
Your laser engraver works by emitting a powerful laser beam from a glass tube fi lled with insulating carbon dioxide
(CO₂), refl ecting that beam off three mirrors and through a focus lens, and using this focused light to etch designs
into certain substrates. The fi rst mirror is fi xed near the end of the laser tube, the second mirror travels along the
machine's Y axis, and the third mirror is attached to the laser head that travels along the X axis. Because some
dust from the engraving process settles on the mirrors, they require frequent cleaning. Because they move during
operation, they also require periodic readjustment using the red dot locator and their attached positioning screws to
maintain the proper laser path.
The integrated cooling system must be used with this engraver to dissipate the heat produced by the laser tube.
Similarly, an exhaust system—typically either an external vent or a dedicated air purifi er—must be used to remove
the dust and gases produced by the engraving process and ensure compliance with laws and regulations for workplace
and environmental air quality. Never operate the engraver without both of these systems operating properly.
With low intensity use, the provided laser tube has an average lifespan around 2000 hours before requiring
replacement. However, constantly running your laser above 70% of its maximum rated power can signifi cantly
shorten its service life. It is recommended to use settings from 10–70% of the maximum rated power to enjoy optimal
performance and longevity.
Note that this is a high-voltage device and, as a safety precaution, it is recommended to only touch its components
with one hand at a time during use.
Note also that the active laser is invisible to the human eye. The visible red dot is only the positioning light and is
harmless. This device should never be used while any cover is open to avoid potentially permanent injury.

2.3 Laser Safety Instructions
When used as instructed, this machine comprises a Class 1 laser system safe for users and bystanders. However the
invisible engraving laser, the laser tube, and its electrical connections remain EXTREMELY dangerous. Used or
modifi ed without care, they can cause serious property damage and personal injury including but not limited to the
following:
As such,
• DO NOT modify or disable this device's provided safety features. Do not modify or disassemble the laser and
do not use the laser if it has been modifi ed or disassembled by anyone except trained and skilled professionals.
Dangerous radiation exposure and other injury may result from the use of adjusted, modifi ed, or otherwise
incompatible equipment.
• NEVER leave any part of the cabinet open during operation except (when needed) the pass-through doors. Never
interfere with the laser beam, do not place any part of your body in any part of the laser path during operation,
and never attempt to view the laser directly. When using the pass-through doors or otherwise risking exposure
to the laser beam, take measures to protect yourself from potentially refl ected laser beams including the use of
personal protective equipment such as protective eyewear specially designed to fi lter the specifi c wavelength of
your engraver's laser with an optical density (OD) of 5+.
• DO NOT stare or allow others to stare continuously at the laser beam during operation even when the cover is
closed and/or wearing protective eyewear. The visible red dot is only the locator light and should not be confused
with the harmful invisible active laser. Do not, however, stare at the refl ected locator either.
• ONLY use this engraver if its automatic shutoff s are working properly. When you fi rst get this engraver and if
you subsequently notice any problems, test them (see below) before undertaking any other work. Do not continue
use if the shutoff s do not occur. Turn off the device and contact customer service or your repair service. Never
disable these shutoff s except as part of a troubleshooting procedure overseen by a trained professional.
• DO NOT ever under ANY circumstances use this laser engraver if the coolant gauge is in or near its red zone or
if the cooling system is not working properly. Always visually confi rm that water is fl owing through the entire
system before turning on the laser tube. Immediately stop use if the cooling system malfunctions.
• ONLY use this engraver when the cooling fans on its rear side have adequate ventilation. They should be at least
8 inches (20 cm) from any obstruction and free of excessive dust or debris at all times.
• DO NOT use generic coolant or 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, fl ammable, explosive, or corrosive materials nearby where they could
be exposed to the direct or refl ected 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 specifi c materials.
• Ensure the area is kept free of other airborne pollutants, as these might pose a similar risk of refl ection,
combustion, etc.
• The laser will easily burn nearby combustible materials
• Some working materials may produce radiation or harmful gases during processing
• Direct exposure to the laser will cause bodily harm including serious burns and irreparable eye
damage

12
2.4 Electrical Safety Instructions

• ONLY turn on the power to this device when it is well grounded, either via a fi rm connection
to a 3-prong outlet or via a dedicated grounding cable fi rmly 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 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 fi 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 specified, ONLY undertake adjustment, maintenance, and repair of the device when it is
turned off , disconnected from its power supply, and fully cooled.
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

3.1 Installation Overview
A complete working system consists of the laser engraving cabinet, its integrated air assist, cooling system, and
exhaust system, all applicable connection cables, and the laser and access keys. The cabinet can use designs
provided by the enclosed engraving software by direct or internet connection with your computer; it can also
engrave designs loaded directly from a fl ash drive. Users can confi gure other additional accessories (such as an
industrial water chiller, fume extractor, or rotary axis) to suit their needs.
Please note the specifi c requirements of your system's installation. Every customer must understand these notes
before installation to execute a proper setup and achieve safe laser performance. If you have any installation
questions or problems, contact our technicians and customer support team.
Any auxiliary equipment must be adjusted to the base machine. Queries may be directed to the dealer or
manufacturer of such equipment.
3.2 Location Selection
Before you install your engraver, select an appropriate location for its use.
Be sure that it meets all of the requirements discussed in the Safety Information above. The location should be
stable, level, dry, and climate controlled to ensure an ambient temperature of 40–95°F (5–35°C) and an ambient
humidity under 70%. In particular, the temperature and humidity together should not be close to the dew point.
It is also advisable to use a windowless room or to use blinds and/or curtains to avoid exposure to the potential
additional heat of direct sunlight. The location should be free of dust and other airborne pollutants and well
ventilated enough to process any fumes produced by the engraving process in accordance with all applicable
laws and regulations. Depending on the materials to be processed, this may require construction of a dedicated
ventilation system. It should be away from children; combustible, fl ammable, explosive, or corrosive materials; and
sensitive EMI devices. The back of the machine should be at least 8 inches (20 cm) from the nearest wall to provide
suitable ventilation for the cooling fans. The power cord should be plugged into a compatible and stable power
source via a grounded 3-prong outlet. No other item should be drawing current from the same fuse. There should be
fi refi ghting equipment nearby and the local fi re department's phone number should be clearly displayed.
It is highly recommended to have an extra work table nearby in order to avoid placing objects on or directly
adjacent to the machine, which could become a fi re or laser hazard.
3.3 Unpacking Your Engraver
Your engraving machine arrives in a wooden crate with its accessories
(including this manual) packaged in the main bay. You should have
placed the crate in a spacious fl at area for unpacking, ideally where
you plan to operate the machine permanently. If you have not already
done so, fi nish removing the crate from around your engraver. Once
unpacked, the machine can be rolled into place.
Step 1. If you have not already done so, fi nish removing the crate
from around your engraver. Each foot is attached to the base
of the crate with a hex screw. Use a 7.8 mm hex wrench to
remove them. Rotate the feet up, unlock the wheels, and roll
the machine into place.
Step 2. Fix it in place by pressing down on the brake pads on the
2 front wheels and rotate the feet down to anchor them. If
needed, suitable fasteners can also be used with the 0.2 inch
(5 mm) holes to further secure your engraver.
3. Installation
Use only the hardware, wiring, and power sources that came with or are compatible with this device.
Installing equipment that your device is not designed to work with can lead to poor performance,
shortened service time, increased maintenance costs, property damage, and personal injury.

Step 3. Retrieve the access keys next to the laser head and take out the accessories pack from the workbed. Check
that you have received all of the following: a power cord, a ground wire, USB and Ethernet cables, a USB
fl ash drive with engraving software included, an exhaust pipe with a hose clamp, a set of hex wrenches, a
tube of silicone sealant, an acrylic focusing tool, keys, and this manual.
Step 4. CAREFULLY remove the rest of the foam packaging material from around the laser tube, the viewing
window, and the rest of the machine. The laser tube is a highly fragile object and should be handled delicately
and as little as possible.
Step 5. Inside the main bay, remove the nylon cable ties from the X axis and the honeycomb table.
Step 6. You may keep the packaging in case of future return but, if you dispose of it or any accessories, be sure to
do so in compliance with applicable waste disposal regulations.
3.4 Electrical Grounding
This device employs a powerful laser. As discussed in the Safety Information above, it is extremely high voltage and
potentially dangerous, so users must securely ground it to avoid the buildup of static electricity. Using a standard
3-prong outlet will provide suffi cient grounding. If you do not have access to a 3-prong outlet, you MUST use the
grounding cable and ensure its proper connection. The far end of the cable should be securely connected to a single
metal rod driven at least 8 feet (2.5 m) deep or to two separate metal rods driven at least 4 feet (1.2 m) deep into soil
located at least 5 feet (1.5 m) from the machine. The resistance along the line should be no greater than 5Ω.
Poor grounding WILL cause equipment failure and create a serious electrical shock hazard. The
manufacturer and/or seller bear(s) no responsibility and assume(s) no liability for any damage, accidents, or
injuries caused by bad grounding connections.

3.5 Exhaust System Installation
Install the provided exhaust pipe directly onto the fan on the left side of your engraver. The pipe can be expanded to
a full length of about 5 feet (1.5 m).
The other end should be connected to a dedicated purifier or (if the fumes are not hazardous and meet local
and national air safety standards) placed out a window. NEVER operate the laser if the vent is not purifying or
removing the fumes produced by the target material. Research materials before use and never operate the laser on
any (such as PVC, tefl on, and other halogen-containing substances) that can produce corrosive, hazardous, or even
deadly fumes.
3.6 Main Power Connection
Confi rm that the labeling beside the connection socket on the machine matches your power supply. Connect one end
of the main cable to the connection socket and the other end to a grounded outlet. Under NO circumstances should
you switch on the device if the voltages do not correspond.
Fluctuation along the line should be less than 5%. If this is exceeded, the fuses will blow. They are located in the
connection socket and are accessible from the exterior. Similarly, do not connect this device to standard extension
cords or power strips. Connect it directly to a grounded outlet or use a surge protector rated over 2000J.
