①Check whether the oil level of the oil dipstick is between \"L\" and \"H\", and whether there are any signs of abnormal oil quality.
②Check whether the cooling water in the water tank is sufficient, whether the water valve switch is turned on, and whether the cooling water is abnormal.
③Check the tension of the water pump belt, fan belt and charger belt.
④Check whether there is any sundries between the fan and the cooling fins of the water tank, if there is, remove it.
⑤Check whether there is any debris piled on the generator set and remove it.
⑥Check whether the generator set is leaking oil or water.
⑦Check whether the battery connector is loose or corroded.
⑧ Read the record card of unit operating parameters, whether various filters and oil have been used over time.

①Listen to whether there is abnormal noise from the diesel generator set, and stop it immediately.
②Check the oil pressure gauge. Under normal circumstances, the oil pressure should not be lower than 35psi under cold conditions.
③Check whether the frequency of the generator set, the voltage value is stable and the working condition of the charger.
④The above three conditions are all normal. After 10 minutes of no-load heat engine, run with load.
⑤ Avoid long-term operation under conditions above 80% of the rated load.
⑥Listen to the diesel engine for abnormal noise under load conditions, check the oil pressure, water temperature (below 92 degrees Celsius), frequency, voltage, and smoke color.
⑦Check whether the generator set has oil leakage, water leakage, air leakage and abnormal vibration of the generator set.
⑧ Check whether the temperature of the bulb shell is abnormal.
