Before the hydraulic motor is officially put into use, it is generally flushed to remove the pollutants, metal chips, fiber compounds, iron cores, etc. left in the Madane. In the first two hours of work, even if the motor is not completely damaged, it will cause a series of failures. Therefore, the motor oil circuit should be cleaned according to the following steps:

1) Clean the oil tank with a dry cleaning solvent, and then remove the solvent residue with filtered air.

2) Clean all pipelines of the motor. In some cases, the pipelines and joints need to be impregnated.

3) Install an oil filter in the pipeline to protect the oil supply pipeline and pressure pipeline of the valve.

4) Install a flushing plate on the collector to replace the precision valve, such as the electro-hydraulic servo valve.

5) Check whether all pipelines are properly sized and connected.
