Preventive maintenance is a systematic approach aimed at regular upkeep of mechanical systems to minimize the likelihood of failure and extend their operational lifespan. This practice involves routine checks, servicing, and repairs conducted before breakdowns occur, thereby enhancing reliability and performance. By adhering to a scheduled maintenance plan, technicians can identify potential issues early, replace worn components, and ensure that systems operate under optimal conditions.

On the other hand, reactive maintenance typically occurs after a system has already failed, leading to potential damage, increased repair costs, and unexpected downtime. Emergency maintenance follows a similar principle, addressing issues as they arise rather than proactively managing them. Neglect represents a lack of maintenance, significantly shortening the lifespan of equipment due to the accumulation of wear and tear without any interventions. Therefore, preventive maintenance stands out as the best practice for sustaining mechanical systems over time.
