Chapter 2 General Safety Information
NOTE :
◎This product is classified as a Class IV laser product. This product emits
light with a wavelength of about 1064nm up to 5W / 10W / 20W / 30W / 50W /
70W, which is not in the visible range, but these beams may cause irreversible
damage to the retina and cornea. Chuangxin Laser recommends that you always
wear qualied and safe protective glasses when operating the laser.
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.
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.

8Chapter 2 General Safety Information
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
WARNING :
◎This device has an output optical head connected to the laser by a ber cable.
Please, be careful dealing with the output head.
3.Optical Operating Instructions
We strongly recommend that you read the following procedures before operating the
laser:
(1) When the power is turned on, do not look directly into the laser light exit hole;
(2) Avoid placing the laser and related optical output devices on the same
horizontal line as the eyes;
(3) Reasonably select safety protection equipment according to the output power
and wavelength requirements of the laser to ensure the safety of operators;
(5) Do not install the sight when the laser is working;
(6) Please make sure to use the sight when the laser is off (such as when
installing the sight on the fixture or observing the end face with optical

9
Chapter 2 General Safety Information
instruments).
(7) Please use the defocus method to mark on the high-reflection material,
otherwise the laser will be directly damaged.
(8) For collimated output, please do not touch the output lens or any solvent
for cleaning. Use lens tissue paper to clean the output lens. After use, please
replace the protective cover of the sight.
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.
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.

of electric shock or burns, and any product disassembled or tampered with by
yourself will no longer enjoy the warranty right.
5.Environment Conditions and Precautions
We strongly recommend that you read the following procedures before operating
the laser:
（1）
Do not expose the device 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 three fans at the rear panel for active cooling. Make

11
Chapter 2 General Safety Information
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.
