On what basis should preventive maintenance be conducted?

• A. Set Schedule
• B. Randomly
• C. Based on weather
• D. Based on fleet size

Answer: (A)

Scheduled preventive maintenance is essential because it ensures routine service happens before failures occur. A set schedule allows each maintenance task—inspections, lubrication, filter changes, blade sharpening, safety checks—to be performed at defined intervals, which reduces unexpected downtime, extends equipment life, and simplifies budgeting and record-keeping. Relying on random timing risks missed services, while basing maintenance on weather or just fleet size ignores actual usage and wear, leading to more breakdowns and inefficiency.
