Preventive maintenance focuses on preventing failures by performing planned, regular work. By scheduling inspections, lubrication, adjustments, and part replacements before problems show up, you reduce the risk of unexpected breakdowns and extend component life. For example, changing engine oil at recommended intervals or replacing filters before they clog helps keep the system reliable. The other ideas describe maintenance after problems occur (breakdown or reactive maintenance) or describe when you perform work (scheduled), but they don’t capture the proactive effort to prevent failures the way preventive maintenance does.
