当长臂挖掘机怠速时，车辆发动机水温显示很高，电力风机、汽车发动机噪音、温度过高吹空调等事故比较常见。这几类情况在长臂挖掘机维修时先直接给车辆的冷凝器和储水箱清理灰尘，确保会整不会影响冷凝器和储水箱良好的导热特性，在平时的时候也可以是不是清理冷凝器和储水箱之间的灰尘。
When the long arm excavator idles, the water temperature of vehicle engine is very high, and accidents such as electric fan, vehicle engine noise, excessive temperature and air conditioning are common. In these cases, when repairing the long arm excavator, first clean the dust directly to the condenser and water storage tank of the vehicle to ensure that the whole will not affect the good thermal conductivity of the condenser and water storage tank. At ordinary times, you can also clean the dust between the condenser and water storage tank.
在挖掘机车辆本身温度很高的时候吹空调，车身怠速抖动会很大，这时候车辆急加速也会显得很无力，可能还会有发动机异响等情况出现。在维修时，看看储水箱的上下管道的温度有没有比较明显的差别，若温度差别大，则需要检查节温器和水泵有没有发振。挖掘机正常工作时上下管道的温度尽量保持一致。
When the temperature of the excavator vehicle itself is very high, blow the air conditioner, and the idle speed of the vehicle body will shake greatly. At this time, the vehicle will also appear weak when accelerating rapidly, and there may be abnormal engine noise. During maintenance, check whether the temperature of the upper and lower pipes of the water storage tank has obvious difference. If the temperature difference is large, check whether the thermostat and water pump vibrate. When the excavator works normally, the temperature of the upper and lower pipes shall be kept as consistent as possible.

在挖掘机刚刚停止作业车身还处于高温时，应熄火停止一刻钟左右再启动，因为热车在重新启动时可能会自动熄火。如果出现自动熄火的情况，可以先启动挖掘机进行热车，再去检查防冻液、储水箱上端的回水管的回水情况，当回水受到阻碍时会导致车身温度过高。
When the excavator has just stopped working and the body is still at high temperature, it should be stopped for about a quarter of an hour before starting, because the hot car may automatically stop when it is restarted. In case of automatic flameout, you can start the excavator to warm up, and then check the return water of antifreeze and the return pipe at the upper end of the water storage tank. When the return water is blocked, the body temperature will be too high.
