Chapter 2 General Safety Information
NOTE :
◎This device is classified as a high power Class IV laser instrument which
emits light with the wavelength of 1080nm and the optical output power is up
to 1500W. 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.
The manufacturer of the laser system is responsible for the safety compliance
according to the applicable standards and regulations.
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 conrm 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.

8Chapter 2 General Safety Information
3-General Safety Instructions
In order to ensure the safe operation and optimal performance of the product,
please follow these warnings and cautions in addition to the other information
contained elsewhere in this document.
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 reects 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 ammable materials around the laser must be isolated.

Chapter 2 General Safety Information
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、Ensure that all personal protective equipment is suitable for the output power
and wavelength range of the laser.
4、Do not install or detach cutting heads or collimators when laser is active.
5、It is forbidden to turn on the laser during the mounting of fiber or cutting
head. 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.
6、Marking on highly reflective materials is feasible, but you must make the
laser out of focus, or else you may damage the laser.
7、For collimated outputs, maintaining a clean output lens is essential. Always
close (re-cap) the collimator after use. Do not touch the output lens and do not
clean it with any solvents.Cleaning with the special solvent and cleaning buds is
allowed as described later on in th is manual.
WARNING:
◎Make sure that the individual protective equipment meets the output power
and wavelength range of the laser.
◎Never look directly into the optical ber or the collimator, and use appropriate
laser safety eyewear when operating this device.
◎Optical damage may result from failure to comply with the above instructions.
Such damage is not covered by the warranty.

10 Chapter 2 General Safety Information
WARNING:
◎Use of controls or adjustments or performance of procedures other than those
set forth in this User's Guide and related documents may result in hazardous
radiation exposure.
4、Electrical Operating Instructions
MFSQ QCW Fiber Laser Series module supply voltage:220VAC:
WARNING:
◎Make sure the shell of this equipment is properly grounded. Any interruption
of the ground loop may result in personal injury.
◎Make sure that the input DC voltage of the laser is the voltage of the normal
DC mains, and wires are connected accurately. Any incorrect wiring method may
cause damage to people or instrument.
◎Before supplying the power to the device, make sure that the correct voltage
of the DC power source is used. Failure to use the correct voltage could cause
damage to the device.
◎No operator serviceable parts inside. Refer all servicing to qualified
Maxphotonics personnel.
◎To prevent short circuit, do not remove shell, detach the laser without
permission and damage the relevant signs. Any product with unauthorized
dismounting shall not be subject to warranty.

5、Environment Conditions and Precautions
We strongly recommend that you read the following procedures before
operating 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、Laser Module has at least three fans at the rear panel for active cooling.
Make sure that there is at least 5cm between fan protector and external objects,
and with sufcient airow to cool the device.
3、Before switching on the device make sure that environmental temperature
and humidity are within a specied range.
WARNING:
◎Optical damage may result from failure to comply with the above instructions.
Such damage is not covered by the warranty.
6、Routine Maintenance
1、Avoid the impaction on the shipper rod of worktable when the laser is
working.
2、The laser and optical lens are fragile, please handle with care.
3、Stop running once device failure, and provide professional treatment.
4、Please follow a set sequence of on-off.
5、The limitation on surface of marking machine is within the working area.
6、Keep the device clean and indoor.
