Field Notes
Why a cold-start inspection is valuable
Warm bearings and cleared alarms can hide useful evidence.
The decision behind the headline
Warm bearings and cleared alarms can hide useful evidence. The useful question is how the issue changes total installed cost, uptime, process capability or risk.
Build a written comparison
List facts, unknowns, quotations, inspection results and assumptions. Price uncertainty rather than pretending it does not exist.
Confirm before purchase
Use manuals, serial data, service records, supplier confirmation and independent inspection. Preserve the evidence with the purchase file.
Marketplace research
Compare complete descriptions, photographs, included tooling, freight terms, control condition, and seller history. A listing title is not an inspection report.
