Maintenance method of refueling system of concrete automatic mixer truck:

1、及时加油

1. Refueling in time

在操作混凝土全自动搅拌车时，驾驶员应随时注意加油量。当燃油表显示燃油量接近“ 0”位置时，请及时加油。在燃油完全用完之前，请勿添加燃油，不仅柴油发动机将在无油的情况下停止运转，而且空气也会进入燃油系统。一旦空气进入燃油系统，燃油不仅被浪费，而且更难以排放。

When operating the full-automatic concrete mixer, the driver should pay attention to the refueling amount at any time. When the fuel gauge shows that the fuel quantity is close to the "0" position, please refuel in time. Do not add fuel until the fuel is completely used up. Not only will the diesel engine stop running without fuel, but also air will enter the fuel system. Once the air enters the fuel system, the fuel is not only wasted, but also more difficult to discharge.

2、注意不要阻塞燃油系统

2. Be careful not to block the fuel system

混凝土全自动搅拌车具有特殊的工作环境，可以轻松堵塞燃油系统，如果燃油系统堵塞，将影响设备的正常运行。因此，一定要检查时间以确保燃料管的顺畅流动。

The concrete automatic mixer has a special working environment, which can easily block the fuel system. If the fuel system is blocked, it will affect the normal operation of the equipment. Therefore, be sure to check the time to ensure the smooth flow of fuel pipe.

3、小心检查燃油系统的坚固性

3. Carefully check the robustness of the fuel system

如果混凝土全自动搅拌车在运行时排气管冒黑烟或发动机难以启动，可能是由于漏气造成的，请注意检查燃油系统的密封性能。

If the exhaust pipe emits black smoke or the engine is difficult to start when the concrete automatic mixer is running, it may be caused by air leakage. Please pay attention to check the sealing performance of the fuel system.

4、保持燃油清洁

4. Keep the fuel clean

大约50％的燃油系统故障是由不干净的燃油引起的。对于汽油发动机，大部分水都包含在燃料中，因此汽油中的水分会腐蚀并破坏燃料供应系统的组件。

Approximately 50% of fuel system failures are caused by dirty fuel. For gasoline engines, most of the water is contained in the fuel, so the water in the gasoline will corrode and damage the components of the fuel supply system.

5、燃料选择很重要

5. Fuel selection is important

选择适合混凝土全自动搅拌车的优良燃料。劣质燃料过滤，杂质，污泥，水分，长期积累，沉淀，油泵过滤器，油管和燃料喷射器，容易堵塞。

Select excellent fuel suitable for concrete automatic mixer. Inferior fuel filtration, impurities, sludge, moisture, long-term accumulation, sedimentation, oil pump filter, oil pipe and fuel injector are easy to be blocked.

如果想要让混凝土全自动搅拌车长期使用，这个时候需要我们加强它的加油系统维护，及时清理废旧燃料油，更新油，另外它的油箱也应该时刻清洗。保持干净卫生。

If we want the concrete automatic mixer to be used for a long time, we need to strengthen the maintenance of its refueling system, clean up the waste fuel oil and renew the oil in time. In addition, its oil tank should also be cleaned at all times. Keep clean and sanitary.
