How do I drain the hydraulic fluid?
The basic process of draining hydraulic fluid is quite simple: remove the appropriate drain plug, replace the necessary filters, and let gravity do its work.
Do you have to drain hydraulic fluid?

When should I change my hydraulic oil in my excavator?
Check the fluids after the first 100 hours of operation, and replace them every 1000 hours after that, or as recommended by the manufacturer. Be sure to keep a close eye on the oil temperature as well, since running your hydraulic power unit with overheated oil can cause a failure.
How do you bleed air out of a hydraulic system?
Releasing the Air Once you have partially closed the cylinder, you can open the bleed valve at the top, providing an escape for the air that has become trapped inside. Leave this valve open until hydraulic fluid flows from the valve, indicating the air has been fully released.
