操作不当造成机械事故四例１．机手贾某买了一辆新的四轮农用运输车，使用未过半年就更换了３个从动盘和两个离合器总成。原因是他的操作方法与人不同，习惯用离合器来控制车速，如下坡时经常只踩下离合器踏板而不挂低档让车辆慢行，遇到凹凸不平的路面也靠踩离合器来调整... Four cases of mechanical accidents caused by improper operation 1. Gam bought a new four-wheeled agricultural truck, the use of less than six months to replace the three driven disc and two clutch assembly. The reason is that his method of operation is different from that of a man who uses a clutch to control the speed of a vehicle. For example, he often only depresses the clutch pedal and does not hang the vehicle to slow down when the downhill is on. The uneven road surface is also adjusted by disengaging the clutch.
