一、日常检查

1、 Daily inspection

目视检查：目视检查应在起动前进行。按照以下顺序彻底检查周围环境和机车底部：

Visual inspection: Visual inspection should be carried out before starting. Thoroughly inspect the surrounding environment and locomotive bottom in the following order:

是否有机油、燃油和冷却液泄漏。

Is there any oil, fuel, or coolant leakage.

螺栓和螺母是否松动。

Are the bolts and nuts loose.

电气线路是否有断线、短路、电瓶接头松动等现象。

Are there any broken wires, short circuits, or loose battery connections in the electrical circuit.

二、启动后检查

2、 Check after startup

喇叭和所有仪器是否完好。

Is the speaker and all instruments intact.

发动机的启动状态、噪音和尾气颜色。

The starting status, noise, and exhaust color of the engine.

是否有机油、燃油和冷却液泄漏。

Is there any oil, fuel, or coolant leakage.

三、燃料的管理

3、 Management of fuel

应根据不同的环境温度选择不同的柴油；柴油不能混入杂质、灰土和水，否则会使燃油泵过早磨损；劣质燃油中石蜡和硫含量高，会对发动机造成损害；日常运行结束后，要给油箱加满油，防止油箱内壁产生水滴；发动机燃油用完或更换滤芯后，必须将道路中的空气排出。

Different brands of diesel should be selected based on different ambient temperatures; Diesel fuel should not be mixed with impurities, ash, and water, otherwise it will cause premature wear of the fuel pump; Poor quality fuel contains high levels of paraffin and sulfur, which can cause damage to the engine; After daily operation, fill the fuel tank with oil to prevent water droplets from forming on the inner wall of the tank; After the engine runs out of fuel or the filter element is replaced, the air in the road must be expelled.

四、过滤元件的维护

4、 Maintenance of filter elements

滤芯的作用是过滤油路或气路中的杂质，防止杂质侵入系统造成故障；各种滤芯应按操作维护手册的要求定期更换；更换滤芯时，检查旧滤芯上是否有金属附着。如果发现金属颗粒，及时诊断并采取改进措施。使用符合机器要求的纯滤芯。

The function of the filter element is to filter impurities in the oil or gas circuit, preventing impurities from entering the system and causing malfunctions; Various filter elements should be replaced regularly according to the requirements of the operation and maintenance manual; When replacing the filter element, check if there is any metal attachment on the old filter element. If metal particles are found, timely diagnosis and improvement measures should be taken. Use a pure filter element that meets the requirements of the machine.
