1. The automatic feeding mixer will clean the fuel system regularly and control the generation of carbon deposition to keep the engine in the best condition.

2.搅拌车使用适当质量等级的油。对于汽油发动机，应根据进气和排气系统的附加设备和运行条件选择SD-SF级汽油发动机机油；柴油机应根据机械负荷使用CB-CD级柴油机油。选择规格基于不少于制造商的规定。

2. Use oil of appropriate quality grade for mixer truck. For gasoline engine, sd-sf gasoline engine oil should be selected according to additional equipment and operating conditions of intake and exhaust system; cb-cd diesel engine oil should be used for diesel engine according to mechanical load. The selection of specifications is based on not less than the manufacturer's specifications.

3.自动搅拌车将定期更换机油和滤芯。在任何质量等级的操作过程中，油质都会发生变化。为防止问题的发生，应根据使用条件定期更换机油，并且机油量应适中（通常是油垢的上限）。

3. The oil and filter element of the automatic feeding mixer will be changed regularly. The quality of the oil changes during operation at any quality level. In order to prevent problems, the oil should be changed regularly according to the service conditions, and the oil quantity should be moderate (usually the upper limit of oil dirt).

4.自动搅拌车坚持曲轴箱的良好通风。

4. Adhere to good ventilation of crankcase for automatic feeding mixer.

5.自动搅拌车的保养三种滤清器：三种滤清器是指空气滤清器，机油滤清器和燃油滤清器，当今的大多数汽油发动机都装有PCV气门（曲轴箱强制通风），但氦气中的污染物会沉积在PCV气门周围，可能会阻塞阀门。因此，必须定期PCV阀周围的污染物。

5. There are three kinds of filters for the maintenance of automatic feeding mixer: air filter, oil filter and fuel filter. Most gasoline engines today are equipped with PCV valve (forced crankcase ventilation), but pollutants in helium will deposit around the PCV valve, which may block the valve. Therefore, the contamination around the PCV valve must be removed regularly.

6.自动搅拌车定期清洁曲轴箱。

6. Clean the crankcase of the automatic feeding mixer regularly.

在发动机运转过程中，焚化室内的高压未燃烧气体，酸，湿气，硫和氮氧化物会通过活塞环和气缸壁之间的间隙进入曲轴箱，并与通过燃烧产生的金属粉末混合。零件的磨损污泥。因此，应定期清洁曲轴箱，以保持发动机内部清洁。

During engine operation, high pressure unburned gases, acid, moisture, sulfur and nitrogen oxides in the incineration chamber enter the crankcase through the gap between the piston ring and cylinder wall and mix with the metal powder produced by combustion. Wear sludge of parts. Therefore, the crankcase should be cleaned regularly to keep the engine interior clean.

7.自动搅拌车的发动机油箱生锈和结垢是更常见的问题。铁锈和水垢会限制冷却液在冷却系统中的活动，降低散热效果，导致发动机过热，甚损坏发动机。因此，必须定期清洁水箱，以去除水箱之间的锈蚀和水垢。

7. Rust and scaling are the most common problems in the engine oil tank of the automatic feeding mixer. Rust and scale will limit the coolant activity in the cooling system, reduce the heat dissipation effect, cause the engine overheating, and even damage the engine. Therefore, the water tank must be cleaned regularly to remove rust and scale between the tanks.
