Air pressure

Blowing hoses is too much air pressure or the wrong hoses. Did you use properly rated hoses? Check the air governor and connections. Even if the governor were allowing high air pressure there is a pop off valve to release excess pressure. "A safety or “pop-off” valve (6) is usually installed in the reservoir closest to the compressor. In the event of over-pressurization, the safety valve allows air to escape, preventing damage to air lines, reservoirs and other components."

What are the dash gauges reading for air pressure? If you have an air drier when was the last time the cartridge was changed?
