Visual inspection: Visual inspection shall be carried out in front of the starter. Thoroughly inspect the surrounding environment and the bottom of the locomotive in the following order:

1, whether there is oil, fuel and coolant leakage.

2. Whether the bolts and nuts are loose.

3. Whether there is disconnection, short circuit and loose battery connector in the electrical circuit.

Second, check after startup,

1, the horn and all instruments are in good condition.

2. Engine starting state, noise and tail gas color.

3, whether there is oil, fuel and coolant leakage.

Third, the management of fuel,

Choose different brands of diesel oil according to different ambient temperatures; Diesel oil cannot be mixed with impurities, lime soil and water, otherwise it will make the fuel pump wear prematurely; The high content of paraffin and sulfur in inferior fuel will damage the engine; After daily operation, the oil tank should be filled with oil to prevent water droplets from forming on the inner wall of the oil tank; After the engine runs out of fuel or the filter element is replaced, the air in the road must be exhausted.

Fourth, the maintenance of the filter element,

The function of the filter element is to filter impurities in the oil circuit or gas circuit to prevent impurities from invading the system and causing failures; Various filter elements should be replaced regularly according to the requirements of the operation and maintenance manual; When replacing the filter element, check whether the old filter element is attached with metal, and diagnose and take improvement measures in time if metal particles are found; Use pure filter elements that meet the requirements of the machine.
