What the used-machine condition survey must capture
Walk the machine with camera and notebook before any timber is cut. Capture leaks, missing covers, loose assemblies, existing rust zones, damaged paint, worn lifting eyes, non-OEM adapters, residual fluid levels, battery state and serial plates. Note on-site access: crane reach, floor loading, concurrent production and bay weather.
If OEM packing drawings are missing, photograph axes before and after lock. Tag residual oils that must remain so destination knows intentional preservation versus contamination.
