请 定期 清 洗 或更 换 过滤 器
1
、观察到筒体内或过滤网上的杂质较多时，可
通过打开过滤器下部的排污阀，自动清洗排
出杂质。
2
、当自动清洗不能排出钳在滤网上的杂质时，
拆下透明筒体取出滤网组件，然后对滤网
进行清洗。
注意：不能损坏滤网，必要时请更换滤网组件。

Protection function introduction
1)
Air pressure protection
When the indicated value of the pressure meter, which is fixed on the back of the cutter, is lower than 0.2
MPa, the protection circuit starts working and the cutter cannot start;
When the indicated value is lower than 0.15 MPa during cutting, the cutting arc will extinguish;
Note: When adjust the air pressure, the panel function must be set to ‘checking gas’
！
2)
Water pressure protection
When the water supply is lower than 0.45L/min, protection circuit starts working and cutter cannot start;
When the water supply is lower than 0.4L/min during the process, protection circuit starts working and
cutting arc extinguishes automatically;
3)
Over-heat protection
When the ambient temperature is too high or the cooling fan is broken, the cutter will be over heated
under the rated current, and heat protection circuit starts working, the cutting arc will extinguish
automatically;
4)
Abnormal power supply protection
When 3 phases power supply misses phase, protection circuit starts working and there is no arc striking;
When 3 phrase power supply is lower than 330VAC, protection circuit starts working and there is no arc
