1. Exterior Details Verification: A new machine has a uniform and bright paint finish, without paint runs or sanding marks. Bolt holes and shaft head gaps are free of paint buildup. Welds are smooth without signs of secondary welding. Hidden corners are free of rust and oil stains from use.
2. Core Component Condition Inspection: The impact wheel protrusions of a new machine are intact and unworn, with zero wear. Hydraulic pipelines are neat, brand new, and show no signs of repair. Internal lubricating oil is clear and free of metal debris, indicating no signs of component aging or wear.
3. Identity and Document Verification: The serial numbers on the engine, frame, and nameplate of a new machine are completely consistent and tamper-proof. A complete original purchase invoice and product certificate can be provided, with no information discrepancies or blurred nameplates.
4. Operational Performance Verification: A new machine runs smoothly under no-load, with regular noise and no abnormal vibration. After 3-5 passes on a standard sandy roadbed, the settlement meets the factory parameters, showing no performance degradation.
5. Verify the purchase channel: Prioritize reputable manufacturers that focus solely on producing new machines. These manufacturers will not sell refurbished or used equipment as new, thus avoiding the risk of buying refurbished machines from the source.
