Daewoo Solar 220LC-V Workshop Manual

I have lost count of how many times a junior guy brings a bolt he snapped off because he guessed the torque. Or worse, someone bypasses a safety lockout because they don’t have the procedure in front of them. That is why the Daewoo Solar 220LC-V Workshop Manual sits on my reference shelf, not on a tablet that runs out of battery mid-job. This is the factory-issued document, 570 pages long, published by Daewoo themselves. If you are working on a Solar 220LC-V track excavator, you need this book, not some third-party rewrite that rounds off critical numbers.

Original Factory Safety Procedures

Safety section alone runs from Track Excavator Safety through to Lifting With Sling. That part of the manual covers the signal words, the location of safety labels, and the specific precautions for digging mode lifting. If you skip the part about high-pressure hydraulic lines storing energy (page 7 of the PDF bookmarks), you are gambling with your life. The manual tells you to use warning tag control lockout procedures during service, and it expects you to follow them. No shortcuts.

Specifications Section for the Solar 220LC-V

Page S0205000 lists general dimensions, working range, and engine performance curves per KS-R1004 standard. That is the kind of data you need when you are ordering replacement hoses or verifying travel speed after a motor rebuild. The manual also includes approximate weight of workload materials, so you can size your lifting gear properly. I have seen guys put a 5,000 lb rock in a bucket rated for less because they did not have the printed spec in hand.

Hydraulic System Troubleshooting and Testing

Hydraulics chapter covers the entire system: troubleshooting, testing, and adjustment. That includes the accumulator, center joint (swivel), cylinders, swing motor, and the swing reduction gearbox (RG10D20B-1). The procedures are step-by-step — start with the test conditions, move through travel speed and steering deviation, then cylinder performance. If you have a drift issue or a sluggish swing, the manual walks you through the pressure checks without assuming you have a dealer scan tool.

Who This Manual Is for

This is for the mechanic who has already pulled an all-nighter chasing a hydraulic leak and refuses to do it again. It is for the fleet owner who needs his excavator back in the hole by Monday morning. And it is for the DIY guy who bought a used Solar 220LC-V at auction and wants to service it himself without burning down his shop. The language is direct, the diagrams are black-and-white factory prints, and every bolt specification comes from the original engineering release.

Source Authenticity: OEM vs Aftermarket

I have seen aftermarket manuals that list the torque for a cylinder gland nut as 300 ft-lb when the factory spec is 415 ft-lb. That kind of error costs you a seal failure on a Friday afternoon. This Daewoo document is the official factory release, publication number 2023-7115E. No photocopy, no condensed version. You get the same binder-filler that Daewoo dealers used. If you want to verify a wiring diagram or a hydraulic circuit, you open this PDF and trust the numbers.

What Else Is Inside

General maintenance procedures include welding precautions, hydraulic system cleanliness guidelines, and bearing inspection steps. The standard torque section (S0309000) saves you from hunting through loose notes. Upper structure covers cab, counterweight, fuel tank, and swing bearing. Lower structure covers track assembly. Engine and drive train includes the air-conditioner service procedure. Everything you need to keep that excavator running without guessing.

You want to trace a travel motor balance issue? Start on the Specifications page for test conditions. You need to adjust track tension? The manual has a dedicated caution section on that. Do not mess with track tension without reading it — high-pressure grease can blind you.

Related manuals you might also need: Daewoo Solar 220LC-V Shop Manual for a different binding format, Daewoo Solar Series Track Excavator 2001 Service Manual for slightly older models, and Daewoo SOLAR 010 1997 Workshop Manual – OEM Bus Repair Specs if you work on that series too. For background on how an Internal Combustion Engine works, you can check external sources, but for the specific Daewoo engine curves, stick with this manual. The Manual Transmission section doesn’t apply here (excavators use hydrostatic drives), but the point stands: OEM documentation is the only source you should trust.

FAQ

Does this manual cover the electrical system and wiring diagrams?

Yes. The table of contents includes Upper Structure and General Maintenance sections that reference electrical components like the cab, fuel tank, and swing bearing. However, the manual does not appear to have a standalone wiring diagram chapter. Electrical service procedures are embedded in the relevant assembly sections.

Is this manual for the Solar 220LC-V with serial number 0001 and up?

Yes.

Can I use this manual for the Solar 200 series?

Not directly. The specifications and hydraulic schematics are specific to the 220LC-V. The solar 200 has different dimensions, engine curves, and attachment configurations. Stick with the manual that matches your machine’s model and serial range.

What torque values are listed in the standard torques section?

The manual includes a dedicated Standard Torques chapter (S0309000) covering fastener torque for general bolts, cylinder gland nuts, and swing bearing bolts. You also get the specific torque for track shoe bolts and hydraulic line fittings from the respective assembly sections. The manual does not round values to “close enough” — they are the factory numbers from Daewoo’s engineering release.
