• Location: Parked in Weinan, Shaanxi, China

Condition summary (high level)

• General: Moderate hours for a 2022 machine — likely significant life remaining if well maintained, but wear items should be inspected.
• Engine & emissions: Check for cold start behavior, smoke under load, oil consumption, turbocharger play and any stored ECM fault codes.
• Hydraulics: Inspect pumps, valves, cylinders and hoses for leaks, noise or slow response. Listen for cavitation/knocking under load.
• Structure & linkage: Inspect boom, arm and bucket linkage for cracks, weld repairs, deformation and pivot pin/bushing wear.
• Undercarriage: Expect moderate wear — inspect track shoes, pins & bushings, rollers, idlers and sprockets; measure remaining shoe thickness and pin/bushing wear %.
• Swing & chassis: Check swing bearing axial/radial play, bolt torque and chassis for any prior repairs or corrosion.
• Cab & controls: Verify gauges, joystick responsiveness, HVAC, safety equipment and any logged fault history.

Recommended pre‑purchase inspection/tests

• Verify VIN/serial number and obtain full service/maintenance history.
• Cold start, idle and full functional test under load (boom, arm, bucket digging cycle, swing, travel).
• Scan ECM for active or historical fault codes.
• Engine oil and hydraulic oil analysis (spectrometric wear, contamination) if available.
• Visual and hands‑on inspection of all pivot points for axial/play — use pry bar to check pins/bushings.
• Detailed undercarriage measurement: pin/bushing wear %, remaining shoe thickness, roller/idler condition, track tension.
• Inspect bucket: cutting edge, teeth/adaptors, welds, bucket floor/side wear and pin condition.
• Inspect all hydraulic cylinders for seal seepage and rod condition. Check hoses/fittings for abrasion or repairs.
• Check final drives/travel motors for leaks/noise and gearbox oil condition.
• Inspect cooling system (radiator/intercooler), air intake and fuel system (filters, water in fuel) — important if machine has been idle.
• Functional test of any quick‑coupler and locking mechanisms if fitted.
• Short digging demo to evaluate pump performance, cycle times and stability.
