They have sent matching arm and controller photographs, but no test findings yet; the pendant is pictured separately and I have asked whether that exact one belongs to the offered package.

Matching photographs still aren't a condition report, and I'd ask who stands behind inspected if your assessment finds a problem before collection.

Amara, yes. Henry, I would also clarify the opportunity to decline after the agreed assessment and what costs remain yours. The travel bill should not become the reason to accept an unknown machine.

They offer a demonstration but have not said what the earlier inspection covered; thanks Jasper for the decline point, I am asking that before arranging travel rather than arguing about it beside the crate.

What would that demonstration establish for you? Watching it move an empty tool doesn't answer wear, history or suitability for your loaded assembly.

I would have the assessor agree the demonstration scope with the seller and distinguish general condition from your application review. A promising used arm can still leave tooling, integration and support work to price separately.
