Use the exact engine manual and a consistent record of work completed.
Identify the equipment accurately
Record engine and transmission model numbers, serial numbers and the manuals that apply to them. Keep installation and commissioning documents if available. Similar-looking engines can have different service requirements, so use the relevant documentation rather than a generic online schedule. Nanni’s download centre is one route to manufacturer material; a dealer can help identify an uncertain model.
Record work in a useful format
For each service entry, note the date, recorded engine hours, work completed, parts used and the person or business responsible. Attach invoices and any observations that require follow-up. A short, consistent record is easier to use than scattered notes. Record symptoms separately from a diagnosis so a technician can assess them without inheriting an assumption.
Prepare for the next service
Review the model’s time-based and operating-hour requirements with the service provider. Ask which items are due and which require access or yard arrangements. Keep the upcoming work list separate from completed work. This guide is about organising service information; maintenance procedures and intervals must come from the exact manufacturer instructions and the technician responsible for the engine.
Your planning checklist
- Model, serial and applicable manuals
- Date and engine hours for each entry
- Parts, invoices and completed work
- Outstanding symptoms and next service plan
