Looking for the Daewoo Solar 470LC-V shop manual PDF? This 601-page factory shop manual covers the 2001 Solar track excavator line, and the parts that matter most are drawn for the 470LC-V specifically: the specifications section is headed "Specifications for Solar 470LC-V," and both the hydraulic and the electrical schematic chapters are titled for the 470LC-V rather than shared across the family. You get complete electrical schematics, hydraulic troubleshooting with pilot pressure and power mode valve testing, and step-by-step rebuilds of the Rexroth main pump, Kayaba main control valve, swing motor, and travel motor with reduction gearbox. Pilot control valve, travel control valve, cylinders, center joint, and track assembly each get their own service chapter. The machine runs a DE12TIS diesel rated at 316 ps at 2,000 rpm, carries 620 liters of fuel and 500 liters in the whole hydraulic system, and wants main relief set to 320 kg/cm2 in normal operation. Your excavator is down; get factory numbers, not forum guesses. Bookmarked with a full text layer, so you can jump to any valve section right from the phone in your cab.

Daewoo Solar 470LC-V Common Problems This Manual Covers
Daewoo Solar excavator hydraulics weak and sluggish under load, pump whines and bucket loses digging force
Check hydraulic oil level and bleed air from the pump case before condemning the pump. Test the power mode valve pressures on page 212: 1.5 bar (22 psi) in power mode, 18 bar (261 psi) in standard mode. Pull a case drain sample; visible metal flake means the pump needs the overhaul procedures starting on page 350.
Manual Section: Hydraulic System Troubleshooting, Testing and Adjustment p. 212Swing hesitates with abnormal grinding noise, weak swing power in both directions
Test swing relief pressure with both swing locks engaged; the setting for the 470LC-V is 280.0 kg/cm2 (3,980 psi), listed on page 208 next to the 270.0 kg/cm2 figure that belongs to the S420LC-V. The test and adjust procedure runs from page 221. Verify brake release pressure at the "SH" port reaches at least 4 bar (58 psi), page 222. If pressures check out, inspect the center joint seals for leakage; that section starts on page 234.
Manual Section: Hydraulic System Troubleshooting, Testing and Adjustment p. 222Machine pulls to one side, one track travels slow and weak under load
Verify track tension on both sides; a tight track drags. Check pilot pressure of 40 ±5 bar (580 ±73 psi) per page 211, then swap travel lines at the center joint to isolate the fault. If the weak side follows the swap, rebuild the center joint (page 234); otherwise pull the travel motor, section starting page 290.
Manual Section: Travel Motor (with Gearbox) p. 290Engine cranks slowly or won't start after sitting overnight in cold weather
Load-test both batteries before touching the starter; the system needs a full 24 volts (page 507) from the 150AH batteries (page 508). Clean and tighten ground connections at the frame and starter. Check charging voltage with the engine running, then drain the water separator and replace the fuel filter if cranking speed is good but firing is not.
Manual Section: Electrical System p. 507Hydraulic oil runs hot during normal digging, power fades as oil temperature climbs
Blow out the oil cooler and dust net with compressed air; packed fins cause most overheating complaints. Check reservoir level and oil condition, then follow the temperature testing procedures starting on page 199 to find a circuit stuck on relief. Replace the pilot filter if restriction exceeds 1.0 kg/cm2 (14 psi), noted on page 523; dirty oil runs hot.
Manual Section: Hydraulic System Troubleshooting, Testing and Adjustment p. 199Frequently Asked Questions
How do I reset the error code on a Daewoo Solar 470LC-V?
To reset error codes 01, 02, or 03, you must first correct the underlying short circuit problem. Once the issue is resolved, turn the start switch from the "OFF" position to the "ON" position to clear the code. p. 539
What does error code EPPR valve open circuit mean on a Solar 470LC-V?
Error code 11 indicates an open circuit in the EPPR valve. This is a malfunction that requires inspection of the electrical circuit for the valve. p. 540
How do I reset the monitor or service alarm on a Daewoo Solar 470LC-V?
To reset the operating hours for filters and oils, open the 'Filter/Oil Information' mode on the instrument panel. Once the filter or oil has been changed, use the reset function in this menu to clear the service interval. p. 529
What are the replacement specifications for hydraulic hoses and seals?
Hydraulic hoses and seals should be replaced periodically, especially fire-related components like fuel system flexible hoses and hydraulic pump outlet lines. Always use new O-rings and oil seals whenever hydraulic assemblies are rebuilt, and ensure they are compatible with the system fluids. p. 17
What are the tightening torques for the Rexroth main pump control housing bolts?
Page 394 lists them by bolt size for the main pump control housing: M6 = 8.5 Nm, M8 = 14 Nm, M10 = 35 Nm, M12 = 69 Nm. p. 394
