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.
◆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; ③
direct 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.
◆The processed objects and discharged materials are required to satisfy requirements as
per local laws and regulations.
◆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 equipment before
power-on.
◆During operating, removing any cover of the equipment 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.
◆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.
◆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);
◆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.
Chapter two of this manual is for Safety Rules. Please refer to the chapter more details
concerning safe operation of the equipment. Users are required to carefully read and abide by all
the requirements of safety.
Note：Note: User Should Comply With the attention and Suggestion in this manual; it
could bring much easier operation.
