The Komatsu PC88MR-6 excavator repair manual helped with hydraulic problems. Using diagrams and instructions, it was possible to find a leak in the boom hydraulic cylinder. Diagnostic code E-103 signaled a pressure drop in the circuit. It was possible to repair the hydraulic system without contacting the service.
