Will it run?
What happens here
Once the engine is running, begin cycling the excavator's hydraulic functions. Operate the boom, stick, and bucket through their full range of motion. Carefully observe the speed and smoothness of the hydraulic movements. During this test, an irregularity is noted: the hydraulics are not performing as expected. Further investigation reveals that the excavator's CPU (Central Processing Unit) is fried and needs to be replaced. This diagnostic step concludes the current maintenance efforts, as the machine cannot be fully operated until the CPU is repaired.
Goal: Verify hydraulic operation and identify any remaining mechanical or electronic problems.
