Maintenance checks are routine inspections performed on equipment, vehicles, or systems to ensure they are functioning properly and safely. These checks can include examining parts for wear and tear, checking fluid levels, and testing performance. Regular maintenance helps prevent breakdowns and extends the lifespan of the equipment. In industries like aviation, automotive, and manufacturing, maintenance checks are crucial for compliance with safety regulations. For example, aircraft undergo regular pre-flight inspections to ensure all systems are operational. Similarly, vehicles require periodic oil changes and tire rotations to maintain performance and safety on the road.
