Please note:
◎ Performances of Maxphotonics MFSC laser meet the CE EMC
certification requirements, the EMC requirements specified in "EMC
Directive" of European market, the anti-interference requirements
specified in "EMC" standard EN55011 emission and EN61326-1: 8006,
and the emission requirements of group 1 classification A specified in
EN55011.
◎ In accordance with relevant national standards and requirements,
the laser must be classified according to its output power and laser
wavelength. All MFSC 700W-1500W Series laser products with high
power belong to Class 4 products (according to section J，1040.10 (d) of
Part Ⅱ , 21 CFR).
◎ According to the standards of EU, the equipment belongs to Class 4
instrument (according to article 9, EN 60825-1).
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,

12
Chapter 2
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:
（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 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 laser in darkened environments.
（8）Do not turn on the laser without an optical coupling fiber or the optical
output connector.
（9）Do not install or detach cutting heads or collimators when laser is

13
Chapter 2
active.
（10）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.
（11）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
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 implement commissioning and calibration of laser output, it’s
necessary to set the quality of the spot emitted from the laser at low
power levels via an infrared viewer, and then gradually increase the output
power.
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

14
Chapter 2
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:
WARNING:
◎ Make sure the shell of this equipment is properly grounded. Any
interruption of the ground loop may result in personal injury.
◎ Make sure the power source connecting equipment is properly
grounded.
◎ In order to further reduce fire hazard, replace the line fuses (if
applicable) with the same types and ratings. The use of other fuses or
material is prohibited.
◎ Make sure that the input AC voltage of the laser is the voltage of the
normal AC mains, and wires are connected accurately. Any incorrect
wiring method may cause damage to people or instrument.
◎ 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.
◎ 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 single-phase AC current (220V 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

15
Chapter 2
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.
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/high temperature
environment. Install the laser in the cabinet with the function of
temperature-humidity control and dust-free.
（2）Operation at higher temperature will accelerate aging, increase
threshold current and lower slop efficiency. If the device is overheated,
stop operation and contact Maxphotonics.
Caution:
◎ Exercise caution to avoid damage to the device.
◎ If the laser will be in an environment of less than 0 degrees Celsius,
drain all coolant out of laser completely to prevent damage to the laser.
