What is the primary purpose of a preventive maintenance program?

• A. To reduce energy consumption.
• B. To prevent unscheduled downtime by performing planned tasks, prolong equipment life, and maintain safe operation.
• C. To guarantee 100% uptime.
• D. To replace parts on a fixed schedule regardless of condition.

Answer: (B)

Preventive maintenance is proactive care that uses planned inspections and servicing to stop problems before they cause a failure. By cleaning, lubricating, adjusting, and replacing parts on a schedule based on time or usage, you reduce the chances of unexpected downtime, extend the life of equipment, and keep operations safe. Energy savings can be a byproduct, but it isn’t the main goal. No maintenance plan can guarantee zero downtime, since some issues arise unexpectedly. Replacing parts on a fixed calendar without checking their condition wastes resources and may not prevent failures if wear isn’t aligned with that schedule.
