Begin with exact model, serial identifier, configuration and included items. Connect the listing to photographs and available purchase, service and modification records. An attractive demonstration does not establish that the current configuration matches the documentation you would use.
Build a dated evidence file. Distinguish seller statements, documents and inspection observations. Obtain answers about current support, software access, warranty transfer and replacement components tied to the exact machine and applicable terms. Do not assume that an original benefit transfers with ownership.
Connect inspection to your work
Prepare acceptance criteria before a demonstration: input material, finished result and observable requirements. Record the demonstrated pieces and steps performed elsewhere. Identify questions requiring a qualified inspector; a sample result is not an inspection of electrical condition, interlocks or extraction.
Compare the sale scope with work needed in your setting. Request evidence or quotes for delivery, installation, service and accessories. Do not power up, defeat safeguards or attempt repairs to resolve an unknown condition. The business calculator can combine supported amounts, but cannot value hidden defects or approve the equipment.
Turn the question into a decision record.
