Chapter 2 General Safety Information
NOTE :
◎ This device is classified as a high power Class IV laser instrument. It may
emit up to 300W average power near 1060nm wavelength. 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. Use appropriate laser safety eyewear
when operating this device. 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 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.
3-General Safety Instructions
In order to ensure the safe operation and optimal performance of the

8Chapter 2 General Safety Information
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 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
WARNING :
◎ This device has an output optical head connected to the laser by a
fiber 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）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 ranges of the laser.

9
Chapter 2 General Safety Information
（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 this 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 fiber 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.

Maxphotonics personnel.
◎ To prevent electrical shock, do not remove covers, 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 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 sure that there is at least 5cm between fan protector and external
objects, and with sufficient airflow to cool the device.

Chapter 2 General Safety Information
（3）Before switching on the device make sure that environmental
temperature and humidity are within a specified 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.
