Cause: Generally speaking, the leakage is caused by a crack in the rubber pipe connecting the condensate tank of the mixer truck and the engine.

保 養：攪拌車變質的冷凝液防銹品質下降，不但容易導致散熱器、管路、軟管等部件的損壞，而且因冷凝液的主要成分是乙二醇，滴漏到地上也會造成環境和空氣污染。但我 們很難通過目測判斷冷凝液是否變質，所以要定期更換冷凝液，切莫等到出現故障再去修理。一般建議車輛每行駛4萬或兩年須更新的冷凝液，另外每兩年須 更換冷凝風扇皮帶。

Maintenance: the deterioration of the anti rust quality of the condensate of the mixer truck will not only easily lead to the damage of the radiator, pipeline, hose and other components, but also cause environmental and air pollution when it drips to the ground because the main component of the condensate is ethylene glycol. However, it is difficult for us to judge whether the condensate is deteriorated by visual inspection, so we should replace the condensate regularly and do not wait until there is a fault. It is generally recommended that the condensate should be renewed every 40000 km or two years, and the condensate fan belt should be replaced every two years.

不好反應：攪拌車發動機點不著火

Bad reaction: the engine of the mixer truck does not ignite

原因：啟動系統出現故障很可能是電瓶生銹或者電瓶滴漏造成的。因為攪拌車發動機的啟動是靠電瓶的電流推動火花塞點火完成的。

Cause: the failure of the starting system is likely caused by the rust or leakage of the battery. Because the start of the mixer engine is completed by the spark plug ignition driven by the current of the battery.

保養：每一兩個月要查看電瓶內的電瓶液是否充足。如果不足，可添加蒸餾水適當的高度。目前攪拌車大都采用免維護電瓶，則不可擅自加水。此外，每年都要檢查一 下電瓶的正負端接點有無生銹或污濁的現象。如果有，要及時到服務站清理干凈，以保持電路的通暢。電瓶恢復后，可延緩電瓶的報廢時間，減少資源浪費和廢棄電 瓶對環境的污染。

Maintenance: check whether the battery liquid in the battery is sufficient every two months. If not enough, add distilled water to the appropriate height. At present, most mixer trucks use maintenance free batteries, so it is not allowed to add water without authorization. In addition, check whether the positive and negative terminal contacts of the battery are rusty or dirty every year. If yes, clean it up at the service station in time to keep the circuit unobstructed. After the battery is recovered, the scrapping time of the battery can be delayed, and the waste of resources and the environmental pollution caused by the abandoned battery can be reduced.

不好反應：攪拌車發動機排氣的噪音大廢氣排放量多

Bad reaction: the engine exhaust of the mixer truck is noisy and the exhaust emission is large

原因：攪拌車發動機的廢氣經高溫發生氧化作用，很可能導致排氣系統泄漏。

Cause: the exhaust gas of the mixer engine is oxidized at high temperature, which is likely to lead to leakage of the exhaust system.

綠色保養：檢查攪拌車排氣系統的管路、接口處是否被廢氣腐蝕，接口墊有沒有被沖壞。若發現攪拌車排氣系統泄漏應及時修理或更換泄漏的部件。每年的檢查一次不僅可以保證攪拌車排氣系統正常運轉，更重要的是減少尾氣中有害物質對環境的污染。

Green maintenance: check whether the pipeline and interface of the exhaust system of the mixer are corroded by waste gas and whether the interface pad is washed out. If leakage is found in the exhaust system of the mixer truck, the leaking parts shall be repaired or replaced in time. The annual inspection can not only ensure the normal operation of the mixer exhaust system, but also reduce the environmental pollution caused by harmful substances in the tail gas.

不好反應：攪拌車油耗增加

Bad reaction: increased fuel consumption of mixer truck

原因：油耗增加的原因很多。但常見又容易被我們忽略的是對攪拌車輪胎氣壓的檢查。攪拌車輪胎胎壓不足不僅會導致行駛阻力增加，造成油耗上升，還會影響攪拌車輪胎的使用壽命。

Reasons: there are many reasons for the increase of fuel consumption. But the common and easily overlooked thing is the inspection of tire pressure of mixer truck. Insufficient tire pressure of mixer tire will not only increase driving resistance and fuel consumption, but also affect the service life of mixer tire.
