A.Safety Precautions
(1)The LASER B1 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
LASER B1 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 II
Class II laser radiation is considered a chronic
viewing hazard.
Class IIIa
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.
2
2
Class IIIb
Direct Class IIIb laser radiation is considered an
acute hazard to the 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 Equipment (PPE, Safety Glasses are
designed to filter specific ranges of laser wavelength. The LASER B1
Safety Glasses provided are specific for LONGER Laser Module;)
when using the machine.
•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 LASER B1.
•DO NOT allow unsupervised access to the LASER B1 to children.
•DO NOT allow access near the LASER B1 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, 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.
(5)Although the LASER B1 has a built-in flame sensor, this
technology should NOT be considered 100% accurate and should
be seen only as a warning system.
During the working process of LASER B1, 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 is properly
contained and extinguished.
It is strongly recommended that a Fire Extinguisher should be
4
4
located within proximity to the LASER B1. 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 LASER B1.
•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 LASER B1 operating unattended.
•ALWAYS clean up clutter, debris, and flammable materials in the
laser LASER B1 bed after use.
•ALWAYS keep a properly maintained fire extinguisher nearby.
•DO NOT allow the USB cable to contact with the laser Beam.
•DO NOT allow the 24V power cable to contact with the laser
Beam.
(6)During the engraving process of the LASER B1 laser engraving
machine, different materials may produce different pungent
odors. Always use LASER B1 laser engravers in open and
well-ventilated areas.
(7)Environmental requirements
Temperature requirement: 10°C~30°C, humidity requirement:
20%~50%, this LASER B1 laser engravers can work normally
5
5
within this range; beyond this range, this laser engravers will be
unable to achieve the best engraving results.
(8)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 easily upon exposure to a laser
beam.
6
6
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 continues 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.
(9)The LASER B1 has built in technology and algorithms to keep its
users and the surrounding environment safe. This said it is
important to understand the LASER B1 is not a toy and should be
operated with care and respect.
(10) Important information regarding your LASER B1
LASER B1 use 24V DC power system:
•Never Use a different voltage Power Adapter.
Make sure to use DC 24V 5A and 7.5A adapters for 20
W and 30W respectively.
•When using an alternative Power Adapter, the Voltage
should always be 24V, Make sure to use DC 24V 5A
7
7
and 7.5A adapters for 20W and 30W respectively.
Higher amperage output Power Adapter can be used
without risk of damage to your LASER B1.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 24V 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 LASER B1 detects 24V present you will see the
motherboard emit a light red glow on the LED of the
Motherboard. This mean the motherboard is powered.
•If when plugging your Power Adapter barrel to your
Motherboard and the Power adapter to mains power a
green LED does not turn on, please verify your power
adapter is receiving Mains Power.

(4) Machine assembly
The machine step-by-step assembly process is described in the
document “LASER B1 Quick Start Guide”. Please follow the guide to
assemble machine.
•During the machine assembly, if there is any unclear place,
please refer to the video “LASER B1 Quick Start Guide”.
•Each unit of the engraving machine has been inspected and
tested. Therefore, in some cases, very small traces may be
left on the profile and the metal shell. These will not affect
the quality. It is normal that it does not affect normal
engraving. Thank you very much for your understanding.
•Be cautious during assembly as some parts may have sharp
edges.
•If you have any questions after receiving the product, please
contact our customer service first.
