讲解挖掘机无法启动的问题。经常复习挖掘机学校对挖掘机日常保养的方法手册的，要求熟练掌握，保持挖掘机各部件清洁，接触良好。转动部位应保持良好的润滑。要经常保持蓄电池处于充足电的状态。这样可以有效提高无电池的使用寿命，挖掘机在正常情况下启动，应先确定安全锁定杆在锁定位置，确认周围区域内无人或障碍物，以免操作不当，产生安全事故，以保障挖掘机学校学员的安全。挖掘机启动前，先把油门操纵杆拉到怠速和高速间的中间位置。挖掘机驾驶员插入钥匙后应先按喇叭，警示周围的其他学员退到安全距离以外后，再将钥匙转动到启动位置。发动机启动后立即松开钥匙，钥匙会自动回到ON位置。挖掘机培训中，不要使启动电机持续运转15s以上，若发动机不能启动，则至少要等2min后再重新启动。挖掘机起动机每次连续工作时间不得超过5s，如果第一次不能启动，应停歇15s左右，再进行第二次启动。当连续三次不能启动时，挖掘机学校教练应带领学员查明原因并排除故障后再进行启动发动机。每行驶1。2~1。5万km，要用检测仪检查启动电流和启动电压。
Manual methods of the daily maintenance of the excavator excavator often review school, master, keep the excavator parts clean, good contact. Rotating parts should keep good lubrication. To keep the storage battery is fully charged state. This can effectively enhance the no battery life, excavator start under normal circumstances, should first determine the safety lock lever in the locking position, confirmed in the area around the unmanned or obstacles, in order to avoid improper operation, production safety accidents, to protect the safety of excavator school students. Before the start of the excavator, the throttle lever is pulled to the middle position between the idle speed and high speed. Excavator driver after inserting the key should press the horn, and other students to a safe distance warning around, then turn the key to the start position. Immediately after the engine starts the key, the key will automatically return to ON position. Excavator training, not to start the motor running above 15s, if the engine can not be started, at least 2min and restart the. Excavator starter every continuous working time is not more than 5S, if the first time does not start, should stop around 15s, and then start the second. When three consecutive cannot start, excavator school coaches should lead the students to find out the reasons and troubleshooting and then start the engine. Every travel 1. 2~1. 50000 km, to start current and start voltage inspection tester.
