A practical checklist

  1. Create the equipment identity from the machine and acquisition documents.
  2. Summarize supplied history in notes and identify its source.
  3. Add new dated maintenance entries only for identifiable work with a reliable date.
Illustrative recordA worked example

Equipment notes: “Purchased used in June; seller supplied invoice for prior repair, other service history unknown.” A July inspection becomes a new maintenance entry with its actual date and findings.

What to avoid

A seller statement is not the same as a verified maintenance invoice. Preserve how you know each fact before relying on it.
