Is the hydraulic oil of a small hydraulic excavator cooperating with black oil because we have used the breaker for a long time to cause the work? In fact, the phenomenon of black oil in the small hydraulic excavator is not only caused by the dust and the quality of the oil seal in the operation, but also broken. Although the dust will affect the quality of the hydraulic oil or the quality of the seal will affect the quality of the hydraulic oil, the main cause of the darkening of the hydraulic oil is due to our daily maintenance.
