How to change Hitachi ex100-3 excavator hydraulics?

Answer 1

To change the hydraulics on a Hitachi EX100-3 excavator, start by ensuring the machine is on a flat surface and securely turned off. Drain the hydraulic fluid by opening the drain plug and remove the old hydraulic filter. Replace it with a new filter, refill the hydraulic system with the appropriate fluid, and bleed the system to remove any air. Finally, check for leaks and ensure the hydraulic functions operate smoothly before using the excavator.
