1. Timely refueling: when operating the small concrete mixer, the driver should pay attention to the amount of fuel 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 oil, but also air will enter the fuel system. Once air enters the fuel system, fuel is not only wasted, but also more difficult to discharge.
2、注意不要阻塞燃油系统：混凝土搅拌机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，检查时间以确保燃料管的顺畅流动。
2. Pay attention not to block the fuel system: the concrete mixer has a special working environment, which can easily block the fuel system. If the fuel system is blocked, the normal operation of the equipment will be affected. Therefore, check the time to ensure smooth flow of the fuel lines.
3、小心检查燃油系统的坚固性：如果小型混凝土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。
3. Carefully check the robustness of the fuel system: if the exhaust pipe of the small concrete mixer truck emits black smoke or the engine is difficult to start, it may be caused by air leakage. Please check the sealing performance of the fuel system.
4、保持燃油清洁：大约百分之五十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。
4. Keep fuel clean: about 50 percent 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 can corrode and destroy the components of the fuel supply system.
5、燃料选择很重要：选择适合搅拌车的匹配燃料。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。
5. Fuel selection is important: choose the right fuel for the mixer. Inferior fuel filtration, impurities, sludge, moisture, long-term accumulation, precipitation, oil pump filter, oil pipe and fuel injector, easy to block.
