是水泥搅拌车在新购入时的保养，行业里将这种保养称为试运转保养，即在水泥搅拌车服役前的试运转，水泥搅拌车在出厂前虽然会有质监部门进行产品的质量检查，在各项指标都合格时才会进入市场销售，但是由于售出前的存储时间和环境的原因，搅拌车可能会产生一些性能上的小瑕疵，这时就需要根据试运转的结果进行改良。
The first is the maintenance of the cement mixer when it is newly purchased. This maintenance is called commissioning maintenance in the industry, that is, the commissioning before the cement mixer is put into service. Although the cement mixer will be inspected by the quality supervision department before leaving the factory and will be sold on the market only when all indicators are qualified, due to the storage time and environment before it is sold, The mixer may produce some small defects in performance, which need to be improved according to the test run results.
一般水泥搅拌车在试运转结束后进行的保养主要有：
The maintenance of general cement mixer after commissioning mainly includes:
1、润滑系统的保养、螺栓的调试、传动皮带的调整、气门和连接件的紧固等。
1. Maintenance of lubrication system, commissioning of bolts, adjustment of transmission belt, fastening of valves and connectors, etc.
2、水泥搅拌车根据使用季节的不同需要进行换季保养，换季保养主要是指在夏季和冬季两种天气下的保养，保养得目的是使车辆适应环境变化以满足使用要求。换季保养的主要工作有更换润滑油和燃油以及防冻液，对于冬夏气候差异较大的高寒地区，冬天时应及时更换防冻液以保障车辆处于良好的工作状态，防止在使用过程中发生危险。
2. The cement mixer truck shall be maintained in different seasons. The maintenance mainly refers to the maintenance in summer and winter. The purpose of maintenance is to make the vehicle adapt to environmental changes to meet the use requirements. The main work of seasonal maintenance includes the replacement of lubricating oil, fuel oil and antifreeze. For alpine areas with great differences in winter and summer climate, the antifreeze shall be replaced in time in winter to ensure that the vehicle is in good working condition and prevent danger during use.
3、水泥搅拌车在发生故障或重大交通事故时的维修保养。这种情况下的保养可根据事故的状态和严重程度进行不同的处理，在没有发生较大损坏时，对车辆进行简单的应对性维修就可以重新上路使用，而当发动机或车辆底盘发生严重损坏时，须对车辆进行检查，更换受损零部件并接受检验后才可以重新启动使用。
3. Maintenance of cement mixer in case of failure or major traffic accident. In this case, the maintenance can be handled differently according to the state and severity of the accident. When there is no major damage, the vehicle can be re used on the road after simple coping maintenance. When the engine or vehicle chassis is seriously damaged, the vehicle must be inspected, the damaged parts must be replaced and inspected before it can be re used.
