Air Compressor Checklist • When operating an air compressor, leave the sound-deadening doors closed. • Check, clean, or replace air filters often. • Know the proper method to check and top off all vital fluid, including the compressor head unit, at each fueling. • Regularly inspect the battery terminals and keep them corrosion-free. • Routinely flush accumulated build-up in the external cooling fins of the compressor’s various intercoolers. • Note changes in odor and temperature of the discharge air. These can be warning signs of initial mechanical malfunction.
