Question about Dewalt d55151 factory reconditioned emglo heavy - duty 2.5hp 4 gallon Electric hand carry compressor
My emglo electric air compressor will not shut off when it reaches 90psi that I set it for and it keeps going so I have to shut it off manually because I am afraid it will blow up if I don't shut it off . The switch works manually,;what is stoping it from working automatically to the pressure I set it at? Model # AM78HC4V
Emglo airmate compressors are set from the factory to shut off at around 125psi. There is an adjustment (remove cover to pressure switch) that will controll the cut-off pressure but it is not recommended changing the factory setting. There is also a safety valve installed that will open at about 160psi. It is a small brass device with a pull ring. When things go wrong with the pressure switch (rectangular box with power cord coming out of one side) the safety will pop open. There is a pressure regulator with round knob on panel that will lower the pressure to the tool, however this regulator does not control the pressure switch. Let you compressor run untill it shuts off and verify pressure to be about 125, if it is then all as well. Good Luck
