1 Safety Instructions and Precautions
It is strongly recommended that any personnel who are
involved with the operation or maintenance of this
equipment should first read the contents of this manual.
Only authorized personnel who have been instructed in
and fully understand the necessary safety procedures
must use this equipment.
1. 1 General Information
1.1.1 Symbols Used in This Manual
This symbol is intended to alert the operator to the
presence of dangerous voltages that may be of
sufficient magnitude to constitute a risk of electric
shock.
This symbol is intended to alert the operator to the
presence of important operating and maintenance
instructions.
This symbol is intended to alert the operator to the
danger of exposure to hazardous visible and invisible
laser radiation.

1.1.2 Some important instructions:
1325/1530 is using laser to cut. Laser light, because of its special
properties, poses safety hazards not associated with light from other
sources. The safe use of lasers requires that all laser users and
everyone near a laser be aware of the dangers involved in laser
operation.
Don' t touch any switches by wet hand in order not to get an electric
shock.
Don't touch the drive device, power supply, the fan and other
electriferous elements when power on.
Ensure that untrained personnel do not open the cover board over the
laser and the protective covering over the beam path, or focus the
cutting head and adjust the beam delivery optics.
1.2 Safety instruction about the laser
This laser is a Class 4 laser product (there are warning
labels on the laser unit and the beam path). The energy
density of the beam is high and the wavelength of the
output beam can be in the range 10.4μm to 11.2μm.
The wavelength range is invisible to the human eye,
and never look directly into the light source or
scattered laser light from reflective surfaces when
adjusting the beam delivery optics and machining.
All personnel must wear safety spectacles. If laser
radiation is exposed to the skin it can burn and cut the
flesh.
Do not cut the high reflectivity materials.
1.2.1 Optical Safety
Laser light, because of its special properties, poses safety hazards not

associated with light from other sources. The safe use of lasers requires that all
laser users and everyone near a laser be aware of the dangers involved in laser
operation. Only authorized personnel who have been instructed in and fully
understand the necessary safety procedures must use this laser equipment. Any
warning signs around the area where is operating must be complied with.
Direct eye contact with the output beam from the
laser will cause serious damage and may cause
blindness.
Avoiding Laser Radiancy
ensure that the beam is not directed towards reflective objects, and
that laser light cannot escape through windows. (not that personal
jewelry is a potential hazard.)
interaction of the beam with certain materials can cause potentially
harmful levels of visible radiation to be emitted. Appropriate
protective measures must be taken in this case.
All personnel in the same room as the laser or anyone who may be
exposed to the laser beam should be informed that a laser is in
operation.

Safety precautions
Exercise caution to protect against specular reflections since reflections at
the laser wavelength are invisible.
Eye safety is great concern when using a high-power laser. There are often
many secondary beams present at various angles near the laser. These beams
are specular reflections of the main beam from polished surfaces. While weaker
than the main beam, such beams may still be sufficiently intense to cause eye
damage. Laser beams ar also powerful enough to burn skin, clothing or paint.
They can ignite volatile substances such as alcohol, gasoline, ether, and other
solvents and can damage the light-sensitive elements in videp cameras,
photomultipliers, and photodiodes.
Use protective eyewear when operating the laser and guard against
inadvertent exposure to skin or clothing. Select eyewear which is
suitable for use with the wavelengths and radiation intensity that the
laser emits.
Do not remove the protective covering over the beam path. During
normal operation, internal reflections are confined within the laser head
and pose no safety hazard.
Never look directly into the laser output port when the power is on.
Only authorize personnel who have been instructed in and fully
understand the necessary safety procedures must use this laser.

Avoid operating the laser in a darkened environment.
Do not use the laser in the presence of flammables, explosives, or
volatile solvents such as alcohol, gasoline, or ether.

1.2.2 Electrical Safety
This equipment contains lethal AC and DC voltages.
These may still be present even when the power is
disconnected.
No electrical hazard exists if the system is operated normally. This
requires the PSU to be properly grounded.
1.3 Safety Requirements in Operation
1.3.1 Safety instructions before starting the machine
10
/

The cable that connected with power supply should be long enough and
have damage-protecting external cover.
The numerical control system of this machine has strict
requirements for the input voltage. Manostat is
strongly recommended, to ensure the voltage conform
to the requirements for the voltage.
Ensure that the range of the cooling water temperature is 15℃~30℃
and must higher than the dew point of the air (according to the
environment temperature and humidity). The environment temperature
must be 15℃~28℃ and the relative humidity is not more than 60%.
Switch on the main power supply, water cooler switch, air switch and
the start up switch of the system in order.
1.3.2 Safety instructions when the machine startup
Before power on, ensure machine to be properly
grounded. Otherwise the electrical system will be
damaged.
Check to make sure whether there are some warning indications on the
screen.
Check all the motor and moving parts, to make sure whether there are
some abnormal vibration and noise.
Ensure that the turning of each motor is correct and the wind directions
of the control cabinet and the beam delivery system are outward.
If there are some problems on the machine, you must solve the
problem in time, then begin to work.
