Safety Precautions
1)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.
2) Laser engravers are divided into several internationally valid
classes based on their performance and the risk of injury.The RAY5
falls into the Class IV (Class 4 IEC standard focus on the American
FDA classification).
Laser class Class Definition
Class I Class I laser radiation is not considered
hazardous.
Class IIa 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 IIa Class II laser radiation is considered a
chronic viewing hazard.
Class II 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.
Class IIIb Direct Class IIIb laser radiation is
considered an acute hazard to the

3
skin and
eyes.
Class IV Class IV laser radiation is
considered an acute hazard to the
skin and eyes from
both direct and scattered radiation.
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.
Please wear Personal Protective(Safety Glasses are
designed to filter specific ranges of laser wavelength. The
RAY5 Safety Glasses provided are specific for LONGER
Laser Module;) when using the machine Equipment (PPE).
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;

3) 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.
4) 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.
6) during operation to ensure that any flare ups/ flame are properly
contained and
extinguished.

It is strongly recommended that a Fire Extinguisher should be
located within
close proximity to the RAY5. Extinguishers should be halogen or
multi-purpose dry chemical. Alternatively or in conjunction with the
Fire Extinguisher it is recommended a “Fire Extinguisher Ball” is
positioned beside the RAY5.
• DO NOT use materials that are highly flammable, explosive or
produce toxic
by-products;
• DO NOT remove material from the cutting bed before it has
cooled;
• DO NOT leave the RAY5 operating unattended;
• ALWAYS clean up clutter, debris and flammable materials in
the laser RAY5 bed after use;
• ALWAYS keep a properly maintained fire extinguisher nearby;
• DO NOT allow the USB cable to come in contact with the laser
Beam;
• DO NOT allow the 12v power cable to come in contact with
the laser Beam;

7) During the engraving process of the RAY5 laser
engraving machine, different materials may produce
different pungent odors. Always use RAY5 laser
engravers in open and well-ventilated areas.
8) Environmental requirements
Temperature requirement: 10°C~30°C, humidity requirement:
20%~50%, this RAY5 laser engravers can work normally within this
range; beyond this range, this laser engravers will unable to achieve
the best engraving results.
9) Below a list of some of the most known hazardous materials that
the user SHOULD NOT attempt to engrave or cut on. If a material is
not in this list, do not consider it to be safe to use. Obtain the Safety
Data Sheet (SDS) from the material’s manufacturer when handling
unknown materials.
Material Reason to avoid engraving / cutting it
PVC (Poly
Vinyl
Chloride)
PVC will emit Chlorine gas when laser cut or laser engraved. This
toxic gas can ruin the optics and motion control system of the laser
engraver, In fact, engraving or cutting PVC is a sure way of voiding
the warranty of your laser engraver
Lexan / Thick
Poly- carbonate
Lexan not only cuts poorly but it also catches on fire very easily.
The window of the laser engraving machine is usually made from
polycarbonate because it does a very good job of attracting
infrared radiation., which is the frequency of light the engraver
uses when cutting and engraving materials. This makes the laser
cutter quite ineffective in cutting polycarbonate materials

ABS
ABS melts upon exposure to a laser beam as opposed to vaporizing
which would
be the ideal reaction needed for laser engraving.
Instead of leaving a crisp image, ABS will melt and leave a gooey
deposit on the surface.
HDPE HDPE melts and catches on fire pretty easily upon exposure to a
laser beam.
Polystyrene
Foam
Only very thin pieces can be laser cut but for the most part,
polystyrene catches
on fire and melts when exposed to a laser beam
Fiberglass Fiberglass is made from two materials; glass and epoxy resin.
The best method of marking glass is etching while epoxy resin
can emit toxic fumes upon laser engraving. These two reasons
make fiberglass a bad choice for a laser engraving material
Polypropylene polypropylene melts and catches on fire easily and then the
melted material con- tinues to burn thereby forming pebble-like
drips that harden on the surface
Coated Carbon
Fiber
Coated carbon fiber emits noxious fumes. Additionally, carbon fiber
can be cut
albeit with some fraying but this is not the case when it is coated.
10) The RAY5 has built in technology and algorithms to
keep its users and the surrounding environment safe. This
said its important to understand the RAY5 is not a toy and should
be operated with care and respect.
11) Important information regarding your RAY5
12v power system:
• Never Use a different voltage Power Adapter.
The RAY5

requires 12v 5 Amps;
• When using an alternative Power Adapter, the
Voltage should always be 12v, the minimum
Amperage output should be 5 Amps. Higher amperage
output Power Adapter can be used without risk of damage
to your RAY5;
• On inserting the power barrel into your Motherboard it is
possible that a small spark is visible. This is NOT
hazardous to your machine and is caused by the 12v
power inrush. If you prefer to avoid this, connect the power
barrel to your motherboard first, then connect your power
adapter to the mains electricity plug;
• Once the RAY5 detects 12v present you will see the
motherboard emit a light red glow on the LED of the
Motherboard. This mean the your motherboard is powered.
• If when plugging your Power Adapter barrel to your
Motherboard and the Power adapter to mains power a Blue
LED does not turn on, please verify your power adapter is
receiving Mains Power.
