This manual is the designated user guide for installation, setup, safe operation, and maintenance of your desktop
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). The laser beam refl ects off three mirrors and passes through a focus lens, after which the focused light can
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. They also require
periodic readjustment using their attached positioning screws to maintain proper laser path alignment. A water
cooling system—typically a pump or chiller—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.
With low intensity use, the provided laser tube has an average lifespan around 2000 working hours before requiring
replacement. The provided power supply should also last around 2000 hours under similar conditions. However,
constantly running your laser above 70% of its maximum rated power can signifi cantly shorten their service lives. It
is recommended to use 10–70% of the full rated capacity 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 that the active laser is invisible to the human eye. Never operate this device while any cover is open to avoid
potentially permanent injury.
Note also that the water cooling system and exhaust system are both absolutely essential to the safe use of this device.
Never operate the engraver without both of these systems working correctly. Cooling water should always be kept
clean and around room temperature, and the exhaust system should always comply with all applicable laws and
regulations for workplace and environmental air quality.
