Hydraulic oil notice of axial piston motors:
Hydraulic system pollution will affect the normal operation of the concrete mixer at any time, and affect the service life of hydraulic pumps and hydraulic motors, serious damage to the pump and motor, so it is very important for the hydraulic system.
Oil change and oil filter replacement:
1. 500 working hours for first run.
2. Replace every 1500 working hours from now on, but at least once a year.
3. Note: When changing oil, replace hydraulic filter element at the same time.
