第一：需要检查好柴油和润滑油，因为柴油发电机长期处于静态，机组本身各种材料会与机油、冷却水、柴油、空气等发生复杂的化学、物理变化.

Please check the diesel and lubricating oil. When the generator is static for a long time, the various materials of the unit itself will have complex chemical and physical changes with the oil, cooling water, diesel oil, air,which will cause hidden but continuous damage to the genset.  

第二：检查电磁阀，电机组在运行时，可通过看、听、摸、嗅来对机组运行时进行检查。在启动时通过听的方法，按下启动按钮三秒钟之后，即可启动。在三秒的启动过程中，正常情况下可听到两次的咔嗒声。若只听到第一响而听不到第二响，就需要检查启动电磁阀是否正常工作。

Please check the solenoid valve. When the unit is running, you can check by watching, listening, touching, and sniffing. When starting by listening, press the start button for three seconds to start. During three seconds of startup, two clicks can normally be heard. If you only hear the first click but not the second, you need to check whether the start solenoid valve is working properly.

第三：检查电池组.电池的维护保养是发电机正常启动关键性的决定因素。电池组出问题时会有“有电压无电流”的故障。出现此情

况能听到启动电机内电磁阀吸合声音，但无带动连轴。电池组出现问题导致无法停机，是因为在试机时采用了停止为电池充电的方式，而导致电池电量不足。也有一种情况可能会被忽略的是，国产电池寿命较短，大概在两年左右，如忘记定期更换，也会出现这种情况。

Please check the battery .Battery maintenance is a key determinant of the normal start-up process of the generator. When there is a problem with the battery , there will be a "voltage without current" . In this case, you can hear the sound of the solenoid valve in the starter motor, but the coupling is not driven. The battery fails to stop due to the battery charge is stopped when the test machine is tested, which leads to the battery power shortage. There is also a situation that may be ignored is that domestic batteries have a short life, about two years or so. This situation may also occur if you forget to replace them regularly.
