Daewoo Solar 290LC-V Workshop Manual – 616 Pages of OEM Factory Specs

You have a Daewoo Solar 290LC-V Workshop Manual in front of you. Not a third-party summary, not a PDF scraped from someone’s hard drive. This is the OEM factory document – 616 pages, serial number 0001 and up, Pub. No. 2023-7113AE. If you have worked on heavy equipment for more than a year, you know the difference between a real shop manual and something that says “covers” on the cover. This one is the real thing.

The number of times I have watched a guy snap a bolt because he trusted an aftermarket torque chart is embarrassing. You don’t get second chances on a swing bearing or a hydraulic line. This manual gives you the factory spec – no guesswork, no translation errors. It starts with a full Safety section (Track Excavator Safety S0102000) that covers lockout procedures, high-pressure line hazards, and the specific warning tag controls you need before any service. Read it. I don’t care how many machines you have worked on – the day you skip the safety section is the day you lose a finger or blow a hose.

Specifications for Solar 290LC-V: What the Factory Includes

The Specifications section (S0202000) gives you general dimensions, working range, engine performance curves per Ks-r1004 standard, and approximate weight of workload materials. You also get performance test conditions, travel speed and steering deviation tests, and cylinder performance tests. Need to know the travel motor balance? It is in there. The manual does not assume you are an engineer – it assumes you have a wrench and a torque wrench and you need the numbers. Page references are not my style, but the data is organized by sub-section: General Dimensions, Dimensions and Working Range, General Specifications. Each table is laid out for a workbench, not a coffee table.

Does This Manual Cover the Hydraulic System?

It covers it from the accumulator to the swing motor. The Hydraulics section (S0702000) includes troubleshooting, testing, and adjustment procedures. There is a dedicated subsection for the Accumulator (S070300). The manual also covers the Swing Reduction Gearbox (S0408000), Track Assembly (S0505000), and the Drive Coupling for the main pump (S0609000). If you have ever traced a hydraulic leak through a generic diagram, you know how useless that can be. This manual gives you the OEM routing. For an internal combustion engine, you still need the Internal Combustion Engine basics, but the pump and valve specs here are specific to the 290LC-V.

The General Maintenance section (S0302000) includes welding precautions, hydraulic system cleanliness, and oil leakage prevention. That section alone is worth the price if you have ever had a contamination failure because someone used a dirty funnel. The manual tells you the acceptable particle size and the correct replacement fasteners – not “use a bolt that fits”.

Safety: The 28-Page Section You Cannot Skip

Track Excavator Safety runs through work-site precautions, high-voltage cable avoidance, and the specific lockout procedure for electrical welding. There is a whole subsection on “Before Starting the Engine” that includes not using ether starting aids – a common mistake that blows preheaters. The manual covers seat belt use, window glass breaking tools, and fire extinguisher placement. It also covers how to properly disconnect batteries before electrical welding. If you are pairing this with a Daewoo SOLAR 010 1997 Workshop Manual – OEM Bus Repair Specs for a fleet, you will see the same consistent safety language across platforms. That is intentional – Daewoo wants you to live.

3 Reasons to Trust OEM Over Aftermarket

First, the torque specs are not converted from metric to imperial by a computer. Daewoo prints them in the units they designed the machine with. Second, the wiring diagrams and hydraulic schematics are machine-specific – not “similar to” some other model. Third, the section on Standard Torques (S0309000) lists fastener grades and tightening sequences that aftermarket manuals leave out. I have a stack of aftermarket manuals in my office that I use for doorstops. This one stays on the bench. If you need a related manual for a smaller excavator, check the Daewoo Solar 130LC-V to 250LC-V 2001 Service Manual – OEM Shop Manual or the Daewoo Solar 210W-V Workshop Manual – OEM Factory Shop Manual for Heavy-Duty Bus.

Torque Specs and Fluid Capacities

The Standard Torques section lists values for bolts, nuts, and hydraulic fittings. The manual also gives you the correct fluid capacities for the hydraulic tank, swing gearbox, and track adjustment system. You will not find a “fill until it looks right” instruction anywhere in this document. Every capacity is stated in quarts or gallons. The General Maintenance section includes a bearing inspection checklist and guidelines for cleaning and inspection. The manual also covers the Fuel Transfer Pump (S0405500) and Fuel Tank (S0405000) – critical if you are working on a machine that has sat for months.

For the transmission and drivetrain, the manual covers the Manual Transmission specifics if equipped, but the 290LC-V uses a hydrostatic drive system, so the emphasis is on pump and motor control. The Swing Reduction Gearbox section tells you the correct oil grade and change interval.

FAQ

Is this a reprint of the original factory manual?

Yes. This is the OEM Daewoo publication, not a scan or a third-party rewrite. Pub. No. 2023-7113AE, serial number 0001 and up.

Does it cover the air-conditioner system?

Yes. Section S0605010 covers the air-conditioner, including refrigerant type, compressor service, and evacuation procedures. Do not guess on refrigerant charge – the manual gives you the exact weight.

What about electrical troubleshooting?

The manual does not have a dedicated “Electrics” section in the TOC, but the Upper Structure section (Cab S0402000) includes wiring for the cab controls. The safety section covers battery disconnect and welding precautions. For detailed electrical diagnostics on the engine control unit, you would need the engine-specific service manual, but the machine wiring is covered.

Will this work for the Solar 290LC-V with a different serial range?

This manual covers serial number 0001 and up. Daewoo issued updates via service bulletins, but the core specs remain the same. If your machine is within that range, you are good. If not, check the publication date – this manual is current as of the print date.

This manual belongs on your workbench, not in a PDF folder you forget about. Access the factory manual now and keep the OEM data within arm’s reach when you have the boom arm off and the hydraulic lines open. Your torque wrench will thank you.
