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

Dewalt d55155 compressor runs to 60 lbs then acts like not enough power and shuts down


Looks like it's an oiled style compressor. Is it getting pretty hot by the time it hits 60psi? Might be low on oil, or the oil has been contaminated with water from condensation. If that's the case then what is happening is the compressor is causing too much resistance for the motor to turn it because of the excess friction. This is could be what is causing it to shut down prematurely.

Can i substitute common motor oil for the proprietary oil sold for my AM78 Emglo 2-tank air compressor?


Dewalt claims that motor oil will cause carbon deposits to form on piston/cylinder head and on the inside of the discharge tube. I see carbon deposits on most all compressors that come in for repair. The carbon is not reason for repair. Usually forgot to add any oil causing rod failure. I believe that most compressor oils are just mineral oil. If the climate in your area is moderate, and you do not use the unit for 8 hours a day, motor oil will work just fine. The crank is steel and the piston rod is made of aluminum (no bearing shell). What makes the unit last longer is change the oil more often (holds very little oil). Good luck

Emglo air compressor too much pneumatic fluid, how to determine correct amount?


What are you putting the oil in? The compressor takes regular non-detergent oil, and it should have a dipstick or a site glass. The guns on the other hand, take the pneumatic oil, and most of them now days, don't even take oil. Only the older ones. I haven't changed or touched the oil in my compressor in 20 years. Any of them. Check it out.

Emglo compressor starts but stalls quickly after


Its not getting fuel. There is a low oil shut off switch as well that go bad. most just bypass this unit. its connected to the on off switch as a 3rd leg. try that
if not check your fuel delivery. either the fuel line pet **** is closed/ clogged or a stuck needle in the carb is causing no fuel

Air compressor does not regulate pressure to set point.


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
