Before Using the laser engraving, please read this safety guide carefully, it mentions situations that require special
attention and includes warnings of unsafe practices that can cause damage to your property or even endanger your
personal safety.
1. This product is a laser engraver system components, must be installed in other manufacturers of laser engraver for
use.And the product belongs to Class 4 laser products, the laser system itself must meet the requirements of IEC 60825-1
latest version, otherwise the product is prohibited to be used.
2. Your laser engraver shall have a protective housing which, when in place, prevents human access to laser radiation.
3. If a protective housing is equipped with an access panel which provides "walk-in" access then:
a)means shall be provided so that any person inside the protective housing can prevent activation of a laser hazard that is
equivalent to Class 3B or Class 4.
b）a warning device shall be situated so as to provide adequate warning of emission of laser radiation equivalent to Class
3R in the wavelength range below 400 nm and above 700 nm, or of laser radiation equivalent to Class 3B or Class 4 to any
person who might be within the protective housing.
c)where “walk-in” access during operation is intended or reasonably foreseeable, emission of laser radiation that is
equivalent to Class 3B or Class 4 while someone is present inside the protective housing of a Class 1, Class 2, or Class 3R
product shall be prevented by engineering means.
NOTE Methods to prevent human access to radiation when persons are inside the protective housing can include
pressure sensitive floor mats, infrared detectors, etc.
Part 1： Security Statment Before Installation
4. The laser itself has a protective cover, the protective cover is fastened by screws. When the laser is installed on the laser
engraver, the protective cover should be checked to be reliably locked, and can not be removed in the energized state.
5. The housing of the laser engraver should have an interlock function. When the housing is opened or removed, the laser
can be automatically turned off.
6. The laser engraver should have an emergency stop button, which can immediately stop the output of the laser when
pressed under unexpected circumstances.
7. The laser engraver should have a reset button, which can resume work under the condition of confirming safety after
lifting the interlock or emergency stop.
8. Laser engraver should use physical keys, dongle, password system and other ways to manage and control, to prevent
personnel without security training operation of this kind of equipment.
9. On the laser engraver any window or channel that can actively observe or passively receive the laser radiation should be
set up warning marks.
10. If the laser burns the skin or eyes, please go to a nearby hospital for examination and treatment immediately
Laser Light can damage the human eyes and skin. Do not expose the eye or skin to laser light directly. This Laser product
has an optical lens and emits a collimated laser beam. The light from this product, both direct and reflected, is very
harmful as it can propagate a long distance while maintaining high optical density. When handling the product, wear
appropriate safety glasses (OD5+) to protect eyes from laser light including reflected and stray light. The reflected and
stray light spilling into an unintended area should be attenuated and/or absorbed.
2.1 Laser safety
We installed a laser shield on the laser, the shield can largely filter out the diffuse reflection of the laser spot.However,
when using laser engraving machine, it is recommended that you wear laser protective glasses. Avoid skin exposure to
type 4 laser beams, especially at close range.Teenagers must have parental supervision in the process of using it.Do not
touch the laser engraving module when the machine is on.
2.2 Fire Safety
Because cutting burns off the substrate, a high-intensity laser beam generates extremely high temperatures and a lot of
heat.Certain materials can catch fire during cutting, creating gases and fumes inside the equipment.A small flame usually
appears here when a laser beam hits the material.It will move with the laser and will not stay lit when the laser passes
by.Please do not leave the machine unattended during the carving process.After use, be sure to clean up debris, debris
and flammable materials in the laser cutting machine.Keep a working fire extinguisher nearby at all times.Smoke or air
pollutant safety. When laser engraving machines are used, smoke, vapour, particles, and potentially highly toxic materials
(plastics and other combustible materials) are produced from the material.These fumes or air pollutants can be hazardous
to health.
Part 2：User Security Statement
2.3 Material safety
Do not engrave materials with unknown properties.Materials Recommended:Wood, bamboo, leather, plastic, fabric,
paper, opaque acrylic, glass.Materials not recommended:Metal, precious stones, transparent materials, reflective materials
etc.
2.4 Use Safety
Use the engraver only in horizontal position and ensure that it has been securely fixed to prevent fires caused by
accidental shifting or dropping from the workbench during work.It is forbidden to point the laser to people, animals or
any combustible object, whether it is in working condition or not.
