At present, there are many machines in the second-hand excavator market that are mixed with real and fake ones. Many consumers buy refurbished or non original painted excavators at high prices because they are not familiar with the machines. Today, our article teaches you how to distinguish excavators by the DOOSAN DH225LC-7.
1. Check the Factory Paint – The First Indicator of Authenticity The originality of the exterior paint is a fundamental clue to verify the machine’s age. Factory-applied paint retains a distinct gloss and texture that fade or wear differently over time. A well-preserved original finish often indicates careful usage and honest representation of the excavator’s age. You can see that the paint and appearance of this Doosan DH225LC-7 excavator are of original factory quality, without renovation or repainting, ensuring quality assurance.
2. Inspect Key Components for Signs of Quality A genuinely well-maintained excavator should feature: The original bucket with minimal wear or deformation Factory-track chains with even wear patterns An engine that runs smoothly, with no excessive exhaust smoke A swing system with no noticeable backlash A hydraulic pump that operates quietly, without unusual noises These factors collectively reflect the machine’s mechanical integrity and maintenance history.
3. Verify All Factory-Engraved Identification Marks Every genuine excavator carries unique serial numbers stamped on critical components, including: Chassis frame, Engine block, Counterweight, Cab plate, Glass panels and so on. If these markings are missing, altered, or illegible, the machine may be a reassembled unit pieced together from parts of different sources. Such equipment often carries operational and safety risks—even if it looks cosmetically appealing.
4. Match Model Codes to Production Years Manufacturers like Doosan use specific model designations for each production period. For example: 2003–2006: LCV series (e.g., DH225LCV) 2007–2010: LC-7 series (e.g., DH225LC-7) 2011–2016: LC-9/LC-9E series (e.g., DH225LC-9) Our featured 2009 model, the Doosan DH225LC-7, aligns exactly with the manufacturer’s coding system—a mark of authenticity. 5. Avoid Emotional Decisions—Prioritize Due Diligence Many buyers face significant financial loss due to the temptation of “good looks and low price.” High-quality used excavators rarely come at unrealistically low costs. Always conduct thorough inspections, verify documentation, and consult experts before purchasing. Rational evaluation over impulse buying can prevent costly mistakes.
Conclusion We hope this guide helps you make informed decisions when evaluating used excavators. At Amincm, we value transparency and supply fully verified machinery with complete history reports.
