LONGER LASER ENGRAVER RAY5 20W
LASER ENGRAVER INTRODUCTION
www.longer3d.com
ATTENTION
The RAY5 engraves and cuts materials by the means of a high-energy diode laser beam.
The hazards associated with a high-energy diode laser beam include the possibility of fires,
generation of hazardous and/or irritating toxic fumes, but more importantly damage to eyes
and skin.
The high energy laser beam can cause severe eye damage, including blindness and serious
skin burns.
Improper use of the controls and modification of the safety features may cause serious eye
injury and burns.
We strongly recommend placing the machine in a well-ventilated room, and at the same
time, the door of the room has a sealing effect and the windows have curtains, so as to
effectively avoid looking directly at the laser beam and some smoke and steam , Particles
and other highly toxic substances. At the same time, you can pay attention to the Longer
products (cover) in the follow-up.
The high-energy diode laser beam can produce extremely high temperatures and significant
amounts of heat as the substrate material is burned away while engraving and cutting. Some
materials are prone to catch fire during cutting operations creating flame, fumes and smoke.
Although the RAY5 has a built in flame sensor, this technology should NOT be considered
100% accurate and should be seen only as a warning system.
P.S. During the working process of RAY5, if a flame is found, the machine will stop the laser
and make a sound to indicate abnormal conditions. Please pay attention to the working
status of the machine.
During operation to ensure that any flare ups/ flame are properly contained and extinguished.
DO NOT look directly into the laser beam;
DO NOT aim the laser beam at reflective surfaces;
DO NOT operate the laser without PPE protection for all persons nearby in the
proximity of the RAY5;
DO NOT allow unsupervised access to the RAY5 to children;
DO NOT allow access near the RAY5 to pets;
DO NOT modify or disable any safety features of the laser system;
DO NOT touch the high energy laser beam;

Class Definition.
Class I laser radiation is not considered hazardous.
Class IIa laser radiation is not considered hazardous if viewed
for any period of time less than or equal to 1x103 seconds, but is
considered a chronic viewing hazard for any period of time
greater than 1x103 seconds.
Class II laser radiation is considered a chronic viewing hazard.
Class IIIa laser radiation is, depending upon the irradiance,
either an acute in- trabeam viewing hazard or chronic viewing
hazard. If viewed directly with optical instruments, Class IIIa
laser radiation is classified as an acute viewing hazard.
Direct Class IIIb laser radiation is considered an acute hazard to
the skin and eyes.
Class IV laser radiation is considered an acute hazard to the
skin and eyes from both direct and scattered radiation.
