Describe the status precisely
Use factual wording: not started during current ownership, last observed running on a documented date, or inspected by a technician with findings attached. Those descriptions mean different things. Avoid calling a unit operational based only on what a previous owner said or the fact that its controller display lights up.
Share the diagnosis you actually have
Attach a written technician report if one exists. Otherwise describe observations without assigning a cause. “Would not start during the last service visit” is clearer than guessing it only needs a battery. Include visible damage, missing components and known fluid leaks without attempting a repair for the sake of the listing.
Inventory the complete package
Photograph the set plate, engine plate, enclosure, controller and accessible components. List missing parts and accessories that remain with the equipment. A buyer needs to know whether the proposal concerns a complete non-running set or a partial assembly. Mark dismantled items and their storage location in your notes.
Offer a realistic inspection arrangement
State whether qualified personnel can inspect the unit, what access requires and whether the machine is still installed. Do not promise a live demonstration when the condition is unknown. Ask bidders to specify whether their offer depends on inspection or is based on the disclosed condition as presented.
Decide whether to diagnose before repairing
If buyers cannot price the uncertainty, ask what additional assessment would help. Obtain a professional diagnostic proposal before authorizing repairs. Compare the proposed spend and delay with actual buyer feedback, keeping any hoped-for price improvement separate from a confirmed offer.
