IV
Safety Precautions
Attention
◆Before using the machine, users are required to carefully read this manual and
other operating requirements, strictly abide by the operating specifications.
Professional are required for operating the machine.
Attention
◆The machine uses class 4 laser (strong laser radiation). The laser radiation may
possibly cause the following accidents: ①emblaze the surrounded flammable
materials; ②generate other radiations and toxic or hazardous gas by processed
objects during laser processing; ③direct irradiation of laser radiation cause
harm to human body. Therefore, fire fighting devices are required in the
operating place of the machine. Stacking flammable or explosive objects near the
machine is strictly prohibited. Good ventilation is a must. Only the qualified
personnel are authorized to approach the machine.
Attention
◆The processed objects and discharged materials are required to satisfy
requirements as per local laws and regulations.
Attention
Laser processing is with potential risks. Users should carefully make sure if the
processed objects are suitable for laser processing.
There is high voltage and potential risk in the laser machine. Unauthorized
disassembly by unqualified personnel is prohibited.
Reliable earthing is required for the machine and related other machine before
power-on.
During operating, removing any cover of the machine is strictly prohibited.
During operating, the operators are required to observe working status of the
machine all the time. In case of any abnormality, it is immediately to disconnect
power supply and take active and corresponding measures.
After power-on, special personnel are required for monitoring. Unauthorized
leaving is strictly prohibited.
It is a must to disconnect the power supply before leaving.
Attention
It is strictly prohibited to placing any unrelated all-reflective or diffusion
reflective objects in the machine to prevent laser reflecting to human body or
flammable materials.
Attention
The environment for the machine should be dry, free of interference and
influences from pollution, vibration, high voltage and strong magnet. The
operating ambient temperature ranges 5-40℃, and the humidity ranges 5-95%
(no dew);

V
The machine should be far from electric appliances sensitive to electromagnetic
interference;
Operating voltage: AC220V, 50Hz. Power-on is strictly prohibited in case of
unstable voltage of the power grid or unspecified voltage.
Attention
Chapter two of this manual is for Safety Rules. Please refer to the chapter more
details concerning safe operation of the machine. Users are required to carefully
read and abide by all the requirements of safety.
