　　Long arm excavator often needs to go to field construction. It will inevitably encounter some emergencies, such as sudden rain, or the machine is directly driven into the ditch. It needs to be repaired in time, so how to do it?

　　发动机系统检修

　　Engine system overhaul

　　发动机是长臂挖掘机的心脏，所以我们应该及时检查发动机，先打开机油口，如果里面有水和泥沙的话，就需要把整个发动机拆除下来，进行分解清洗，确保各个零件的清洁之后，再进行复装。如果活塞被卡死的话，需要检查一下活塞开口是否过大，如果开口超过0.08毫米的话，就需要更换配件了。

　　The engine is the heart of the long arm excavator, so we should check the engine in time, open the oil port first, if there is water and silt in it, we need to remove the whole engine, decompose and clean it, ensure that all parts are clean, and then reinstall it.

Check the diesel tank again. If there is water and mud in the tank, we need to drain the impurities before doing a thorough cleaning and replacing the diesel filter.

　　液压系统检修

　　Hydraulic system maintenance

　　液压油箱是一个密闭的容器，所以在油箱内部通常不会有杂质进入，但是油箱盖子上设有换气装置，所以如果长臂挖掘机被浸泡时间过久的话，也会有少量的水和泥沙渗入。

　　The hydraulic tank is a closed container, so there is usually no impurities in the tank, but there is a ventilation device on the tank lid, so if the long arm excavator is soaked for too long, there will be a small amount of water and silt infiltration.

　　这时我们需要放掉液压油，并且将油箱彻底清洗干净。然后还要检查一下控制阀和其他部件，确保一尘不染，再更换新的液压滤芯以及液压油。

　　We need to drain the hydraulic fluid and clean the tank thoroughly. Then check the control valve and other parts to ensure spotless, and then replace the new hydraulic filter and hydraulic oil.

　　此外 长臂挖掘机租赁人员认为蓄电池的检查要重视，看一下蓄电池是否进水，如果有的话，就需要把电解液倒掉，并更换新的电解液，换好后别忘了试一下能否充电，若不能，就需要更换蓄电池了。

　　The long arm excavator leasing personnel think that the inspection of the battery should be paid attention to. Let's see whether the battery is filled with water. If there is, we need to pour out the electrolyte and replace the new electrolyte.
