The long-term use of a generator set or the reminder that it needs maintenance if left unused for a long time. In order to maintain the performance of the generator set and keep it in good condition, the following is an example of a customer's generator that encountered some problems due to long-term use without regular maintenance, as well as the maintenance process. The maintenance of the generator mainly involves these steps. Firstly, it is important to add oil through the oil filling port before starting the generator. When refueling, the engine should be placed in a horizontal position and attention should be paid to the changes in the generator oil level. Generators require the use of multi-stage viscosity oil, as multi-stage viscosity oil is suitable for a wide range of operating temperatures and has a consumption rate about 30% lower than single-stage viscosity oil. After adding oil, wait for a while before checking the oil level on the generator oil gauge.

The schematic diagram of the generator shows that the correct oil level is when all the oil flows into the oil pan. Each oil filter should be filled with clean oil before being installed on the engine. The performance level of the oil represents the level of oil additives. Only by selecting an adequate level of oil can the generator be reliably protected throughout the oil change cycle. Secondly, when maintaining the generator, it is important to fill the cooling liquid before starting. When filling, open the bleed valve of the cooling system on the upper part of the engine, slowly fill the cooling liquid from the water inlet of the radiator tank into the engine until no bubbles are discharged from the bleed valve. The cooling liquid should be filled below the neck of the water inlet of the radiator tank, and should not be overfilled. For the cleaning of the entire generator set, due to the long-term placement of the generator, it is easy to accumulate dust。

The residue of diesel and oil affects the normal operation of the generator, so we should regularly clean their style, water grid, etc., and also regularly check the generator to ensure its normal operation.
