other operat ing requirements, strictly abide by the operat ing specifications.
Professional are required for operat ing the machine.
Attention
5The machine uses class 4 laser (strong laser radiation). The laser radiation may
possibly cause the following accidents:
1. Emblaze the surrounded flammable materials;
2. Enerate other radiations and toxic or hazardous gas by processed objects
during laser processing;
3. Direct irradiation of laser radiat ion cause harm to human body. Therefore,
firefight ing 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
5The processed objects and discharged materials are required to sat isfy
requirements as per local laws and regulations.
Attention
5Laser processing is with potential risks. Users should carefully make sure if the

5There is high voltage and potent ial risk in the laser machine. Unauthorized
disassembly by unqualified personnel is prohibited.
5Reliable earthing is required for the machine and related another machine
before power-on.
5During operating, removing any cover of the machine is strictly prohibited.
5During 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.
5After power-on, special personnel are required for monitoring. Unauthorized
leaving is strictly prohibited.
5It is a must to disconnect the power supply before leaving.
Attention
5It 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
5The environment for the machine should be dry, free of interference and
influences from pollution, vibration, high voltage and strong magnet. The
operating environment temperature ranges 10-35°C, and the humidity ranges
5-85% (no dew);
5The machine should be far from electric appliances sensitive to electromagnet ic
interference;
5Operating voltage: 110V, 60Hz / AC220V, 50Hz. Power-on is strictly prohibited in
case of unstable voltage of the power grid or unspecified voltage.
Attention
5Chapter 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.
