Proper maintenance of air compressors is essential to ensure their longevity and efficient operation. Regular checks on the compressor's oil levels, filters, and belts are necessary to prevent breakdowns and maintain performance. It is also crucial to monitor the pressure levels to avoid overloading the system, which can lead to accidents or equipment failure. Safety precautions, such as using the correct pressure rating for the tools and wearing protective gear, are vital when operating air compressors, as mishandling can result in serious injuries.
