Hunting for the Daewoo Solar 220LL, Solar 290LL shop manual PDF? This is it: 576 pages of factory shop procedures (OEM #2023-7134E) covering both track excavators, from the swing bearing to the boom and stick. The hydraulics section alone is worth the price; you get troubleshooting, testing and adjustment routines, plus rebuild procedures for the main pump, swing motor, travel motor, grapple rotate motor, and main control valve. Full hydraulic and electrical schematics, wiring diagrams, and a standard torque chart back up every job. Set your 1/2-inch split flange bolts at 15 to 18 ft lb, and know the fuel tank holds 310 liters (81.9 gallons) before you order diesel. A weeping swing motor won't diagnose itself. Bookmarked and text-indexed; open it on your phone at the machine, search the spec, and get back to digging.
