When the operator does service or maintenance for machine, it is better to have an assistant who is familiar with risk and
high-voltage laser radiation knowledge besides him. Once an accident occurs, the assistant can help the operator turn off the
laser equipment.
当操作员对机器进行保养或维护时，最好有一位助手，助手除了要熟知激光泄漏风险和高压激光辐射知识外，还
要帮助操作人员。一旦发生事故，助手可及时关闭激光设备。
2.2.2 Allow air circulation appropriately
适当通风
Some materials during the laser processing will produce harmful fume, so the operator might as well install exhaust system /
fume purifier.
在激光加工过程中，某些材料会产生有害的烟雾，因此最好安装排气系统或使用烟雾净化器。
2.3 Warning
警告
2.3.1 Wear Protective Glasses / Goggle
穿戴护目镜
Protective glass plays a protective role (for direct radiation, radiation reflected and scattered radiation). However, even if the
operator wears the goggle, he can not look directly at the spot very often, intense laser radiation still can damage the
protection tool.
激光防护镜可以起到保护作用（用于防护直接辐射，反射辐射和散射辐射）。即使戴上护目镜，操作者也不能经
常直接注视打标区域，强烈的激光辐射仍有可能损坏护目镜而对眼睛造成伤害。
Before wearing the glass, please:
穿戴护目镜前，请遵从：
1. Check whether it is damaged or not.
检查护目镜是否完好。
2. Be sure you are wearing the right glass, because the protective glass for CO2 laser can’t protect the laser radiation emitted
from fiber laser (CO2 laser and fiber laser has different wave length).
确保您佩戴正确的护目镜，因为用于
CO2
激光的护目镜无法防护来自光纤激光器发出的激光辐射（
CO2
激光器
和光纤激光器的波长不同）。
2.3.2 Fire
火灾
Although the four-level laser output power is not high, the operator should pay more attention to the fire when the laser is
working in high power and low speed.
尽管
4
级激光的输出功率不高，但当激光器以高功率低速工作时，操作人员应注意防范火灾。
2.3.3 Interlock Machine Door
联锁机门
Each machine has the interlock, the machine door must be closed during operation in case of the laser leak. Once you open the
door of machine, the machine will stop working, and there will not be any laser output.
每台机器都有互锁装置，在操作时必须关闭机器门，以防激光泄漏。机门一旦打开，机器将停止工作，并且将不
会再输出激光。
If you want to continue to run the machine, you have to close the door of machine, and click “Mark” in the software once
again!
如果要继续运行机器，则必须关闭机器门，然后再次单击软件中的“标刻”
