Final answer:
It is true that you should check the oil level of an air compressor with an oil supply before driving. This is necessary to ensure the compressor functions efficiently and to avoid excessive wear and tear. Air in brake lines must also be removed for brakes to function properly.
Step-by-step explanation:
True, before driving or operating a vehicle or machinery equipped with an air compressor, it's essential to check the oil level if the compressor has an oil supply. Proper oil level is critical for the efficient operation of the compressor, as the lubrication ensures that all moving parts function smoothly and reduces the risk of overheating and subsequent damage. Not checking the oil can lead to inefficient operation and increased wear and tear on the compressor.
In relation to brake systems, for instance, while air compressors are often found in larger vehicles with air brake systems, the principles of maintaining equipment apply broadly. An air compressor that is low on oil may not operate efficiently, affecting the performance of the brakes. Additionally, as mentioned regarding brake systems, any presence of air within the brake lines must be addressed by bleeding out the air to ensure that the brakes respond correctly and promptly when force is applied. Compressed air systems require regular maintenance for safety and efficiency.
