定期檢查主機及油源是否有漏油現象。 如有漏油，應及時更換密封圈或組合墊。  

根據機器的使用情況和油的使用壽命，定期更換濾油器和濾芯，更換液壓油。  

長時間不做試驗時，注意關閉主機電源。 如果機器處于待機狀態，應將轉換開關打到“負載”檔，因為如果轉換開關打到“快回”檔，電磁閥已通電，會影響設備的使用壽命。 

1.  定期檢查控制器后面板連接線是否接觸良好。 若松動，應及時擰緊;  

二、測試完畢后，如果有很長一段時間機器不使用，關掉控制器和電腦;  

3. 控制器上的接口相互對應。 接口錯誤可能會對設備造成損壞。  

四、拔插控制器上的接口必須關閉控制器電源。  

5、根據機器的使用和石油的生活,定期更換吸油過濾器濾芯,更換液壓油,定期檢查主機和油源是否有漏油,如石油泄漏,應及時更換密封圈或組合墊。

Machine maintenance  

1. Check the screws at the clamping mouth regularly, and tighten them in time if they are loose;  

2. The sliding surface of the steel plate in contact with the lining plate and dovetail groove surface of the lining plate should be kept clean, and a thin layer of molybdenum disulfide grease should be regularly coated;  

3. Check the rotation of the sprocket regularly.  Tighten the sprocket again if it is loose.  

Oil source maintenance  

Check the main engine and oil source regularly for oil leakage.  If there is oil leakage, the sealing ring or combined pad should be replaced in time.  

According to the use of the machine and the service life of the oil, regularly replace the oil filter and filter element, replace the hydraulic oil.  

When not doing the test for a long time, pay attention to turn off the host power.  If the machine is in standby state, the transfer switch should be switched to "load", because if the transfer switch is switched to "fast back", the solenoid valve is energized, will affect the service life of the equipment.  

Control system maintenance  

1. Periodically check whether the cables on the rear panel of the controller are in good contact.  If loose, should be tightened in time;  

2、 after the test, if the machine is not used for a long time, turn off the controller and computer;  

3. Interfaces on the controllers correspond to each other.  An incorrect interface may damage the device.  

4, plug and unplug the interface on the controller must turn off the controller power.  

5, according to the use of the machine and the life of oil, regular replacement of oil absorption filter element, replacement of hydraulic oil, regular inspection of the host and oil source whether there is oil leakage, such as oil leakage, should be replaced in time seal ring or combined pad.
