Alarm
The machine uses class 4 laser (strong laser radiation). The laser radiation may possibly cause the following
accidents:
emblaze the surrounded flammable materials;
generate other radiations and toxic or hazardous gas by processed objects during laser processing;
direct irradiation of laser radiation cause harm to human body. Therefore, firefighting 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.
Note
