Pilot circuits, main hydraulics, electrics, and pressure adjustment run end to end through this 166-page Sumitomo SH200-3, SH220-3 technical manual PDF for the hydraulic excavator, with parts compatibility noted for SH200-2, SH220-2, and SH200GT-3 machines. Hydraulic circuit diagrams trace oil from the pump through the control valve into the travel, swing parking, boom, arm, and breaker circuits, while pilot hose tables show you which line lands on which port. Close to a third of the book covers the electrical side, from circuit diagrams and engine idling control to fault procedures for low oil pressure, overheating, and alternator trouble. On an SH220-3, H mode current should read 424 mA at maximum and 307 mA at minimum, and main relief, swing motor relief, and pilot pressures come with their measuring and adjustment methods. It's you, the machine, and nobody to call. Bookmarked and text-searchable, this PDF rides along on your laptop or phone to wherever the excavator is parked.
