Part of the Doosan Repair Manuals.
This is the factory shop manual for the Doosan DX235LCR-5, publication 950106-01109E, covering 2014-2019 machines. If you bought this excavator, you bought it for the tail - 1,680 mm swing radius and 1,060 mm counterweight clearance let it work a single lane without eating the next one. The manual covers the whole machine: engine, hydraulic system, upper structure, lower structure and chassis, front group, electrical system, plus full schematics. This is a -5 generation Tier-4 era machine with electronic engine control, so the electrical section actually matters here - it is not three pages of fuses. You also get the numbers a working shop needs: component weights for rigging, pressures, capacities, and step-by-step teardown for pumps, cylinders, and travel gear.
