How this planner works
Choose the engine type and how it is used, and the planner lists the service items that manufacturers typically specify for that kind of engine, with the usual interval ranges. Dusty conditions, heavy loads, very cold weather, humid or coastal air, seasonal use and daily use each add notes that reflect how makers adjust their schedules for severe service.
Where the intervals come from
The ranges are drawn from the service schedules that major engine and equipment manufacturers publish for their products, condensed into typical figures. They are deliberately given as ranges because no two engines are the same: a lawn mower engine might call for an oil change every 50 hours, a premium generator engine every 100 hours. Your owner’s manual gives the exact interval for your model, and following it is also what keeps the warranty valid.
Using the checklist
- Print it and keep it with the equipment, or photograph it.
- Note the date and the hour meter or odometer reading each time you complete an item.
- Our service log tool keeps a simple record in your browser if you look after several machines.
For the reasoning behind each item, see our small engine maintenance schedule, generator maintenance checklist and diesel engine maintenance schedule.
