Lubrication changes, checking and adjusting system pressures, and replacing filters are considered ___________ tasks.

Lubrication changes, checking and adjusting system pressures, and replacing filters are considered ___________ tasks.

• A. Corrective maintenance
• B. Predictive maintenance
• C. Preventive maintenance
• D. Reactive maintenance

Answer: (C)

These tasks are preventive maintenance because they’re proactive steps taken to keep equipment in good condition and prevent a fault before it happens. Lubrication changes reduce wear and heat, checking and adjusting system pressures keeps operation within design limits, and replacing filters prevents contamination and flow problems. Doing these routinely or based on usage helps extend life, improve reliability, and reduce unexpected downtime. They’re not responses to a failure (that would be corrective or reactive maintenance) and not based on predictive data about a future failure.
