Chapter 2 General Safety Information
NOTE :
◎ This device is classified as a high power Class IV laser instrument. It may
emit up to 4000W average power from 1060nm to 1100nm. This level of
light may cause damage to the eye and skin. Despite the radiation being
invisible, the beam may cause irreversible damage to the retina. Laser
safety eyewear is not provided with this instrument, but must be worn at all
times while the laser is operational.
2-Laser Protection
1、Laser Protection Requirements
You must wear the safety protective glasses while operating the laser,
and rationally select the safety protective glasses according to the lasing
wavelength of the laser. If the device is a tunable laser or Raman product,
it emits light over a range of wavelengths and the end user should confirm
the laser safety eyewear used protects against light emitted by the device
over its entire range of wavelength.
2、Laser Protective Equipment Suppliers
Maxphotonics recommends material or equipments provided by following
laser protective equipment suppliers for you, including LaserVision USA,
Kentek Corporation, Rochwell Laser Industries, etc. All the supplier
information is provided by Maxphotonics only for the convenience to use,
so Maxphotonics assumes no responsibility for any problem caused by
using the products of abovementioned suppliers.

Chapter 2 General Safety Information
4-General Safety Instructions
1、Specular Reflection
There are often numerous secondary laser beams produced at various
angles in the output port of the laser. These divergent beams are produced
when the primary beam of laser reflects off a smooth surface, and they are
called specular reflections. Although these secondary beams may be less
powerful than the total power emitted from the primary beam, the intensity
may be great enough to cause damage to the eyes and skin as well as
surface of materials.
WARNING:
◎ You must exercise caution to avoid/minimize specular reflections as
these laser radiations are invisible!
2、Safety Instructions of Accessories
Optical accessories relevant to the laser, such as light-sensitive elements
that may be damaged from exposure to the laser light, video cameras,
photomultipliers and photodiodes, need related protections.
WARNING :
◎ The Maxphotonics MFSC laser light is strong enough to cut or weld
metal, burn skin, clothing and paint. In addition, this light can ignite
volatile substances such as alcohol, gasoline, ether and other solvents.
During the operating process, the flammable materials around the laser
must be isolated.
3、Optical Operating Instructions
We strongly recommend that you read the following procedures before
operating the laser:

10 Chapter 2 General Safety Information
1、Never look directly into the laser output port when the power is turned
on.
2、Avoid positioning the laser and all optical output components at eye
level.
3、Equip with laser beam casing.
4、Remove the end-cover before switch ON the laser. Or else the output
head will be damaged irreversibly.
5、Ensure that all personal protective equipment is suitable for the output
power and wavelength range of the laser.
6、Use the laser in a room with access controlled by door interlocks. Post
warning signs. Limit the safety areas to operate the laser.
7、Please do not operate the laser in darkened environments.
8、Do not turn on the laser without an optical coupling fiber or an optical
output connector.
9、Carry out commissioning, calibration and focusing at low output power
and then increase the output power gradually when the calibrating and
focusing work is done.
10、Do not install or detach cutting heads or collimators when the laser is
active
11、Make sure that the laser is shut down and the power is off before you
install or detach cutting heads or collimators.
12、If the equipment is operated in a manner not specified in this
document, the protection devices and performance of the equipment may
be impaired and the warranty will be voided.
CAUTION:
◎ The output of the laser is delivered through a lens with an anti-reflection

11
Chapter 2 General Safety Information
coating. If the backward-stage light path of your laser has the optical
lens, please strictly inspect the lens of the output head and the backward-
stage lens of the laser, and ensure that there is no dust and any other
impurity on the lens. Please note that any macroscopic attachment may
cause extreme damage to lens or burn the laser or any backward-stage
light path equipment.
◎ For cleaning instructions of the lens, please refer to the "Optical Fiber
Connector Inspection and Cleaning Guide".
◎ Hot or molten pieces of metal may be produced when the laser is under
operation. Exercise caution if debris is produced in operation.
◎ When you carry out commissioning and calibration of the laser output,
you must set the laser output at low power level and then gradually
increase the output power during checking the quality of the light spot
emitted from the laser via an infrared viewer.
WARNING:
◎ Make sure that the individual protective equipment meets the output
power and wavelength range of the laser.
◎ Never look directly into the optical fiber or the collimator, and make
sure you wear the safety protective glasses in each operation.
4、Electrical Operating Instructions
We strongly recommend that you read the following procedures before
operating the laser:
1、Make sure the shell of this equipment is properly grounded. Any
interruption of the ground loop may result in personal injury.
2、Make sure the power source connecting equipment is properly
grounded.
3、In order to further reduce fire hazard, replace the line fuses (if

12 Chapter 2 General Safety Information
applicable) with the same types and ratings. The use of other fuses or
material is prohibited.
4、Make sure that the input AC voltage of the laser is the voltage of
the normal AC mains (Three-phase four-wire 380V AC), and wires are
connected accurately. Any incorrect wiring method may cause damage to
people or instrument.
5、The equipment does not have any part which can be maintained by
operators, and all the maintenance operations must be finished by the
professionals of Maxphotonics Co., Ltd.
6、To prevent electrical shock, do not remove enclosure, detach the laser
without permission and damage the relevant signs. Any product with
unauthorized dismounting shall not be subject to warranty.
WARNING:
◎ The input voltage of the laser is triple-phase AC current (380V AC),
which may cause risk of electric shock. All the relevant cables and
connection wires have potential hazards.
5、Environment Conditions and Precautions
For ensuring the safety of the laser working area, suitable enclosures
shall be applied, including but not limited the laser safety signs and the
interlocking devices. Corresponding operators must be trained and
examined and know the normal safety specifications for operating the
laser.
Meanwhile, it is important that the output components shall not be installed
at eye level.
Because of interaction of the laser and the metal material, the radiation of
high-level ultraviolet light or visible light may be produced. Make sure that
the laser is provided with the protective cover to prevent the eyes or other
parts of human bodies from damage by radiation.

13
Chapter 2 General Safety Information
We recommend that you comply with the following operating
measures to prolong the service life of the laser:
1、Do not expose the laser to a high moisture environment.
2、The device is equipped with cooling fans. Make sure that there is
sufficient airflow to cool the laser, any objects or debris that cover the
ventilation holes must be removed at all times.
3、Operation at higher temperature will accelerate aging, increase
threshold current and lower slop efficiency. If the device is overheated,
stop operations and contact Maxphotonics.
4、Ensure that the work surface is properly vented. There may be gases,
sparks and debris generated from the interaction between the laser and
the work surface, and they could pose additional safety hazard.
CAUTION :
◎ The device may be damaged with incautious operation.
