20 Most Recent Dewalt d55151 factory reconditioned emglo heavy - duty 2.5hp 4 gallon Electric hand carry compressor Questions & Answers


There is no point asking. If your spare part is also type 1 or type 3 compatible then who cares? In case you find a spare part that is only compatible to the type 3 machine and yours is type 1 then you should find the type 1 one because this is only compatible with your machine because that spare part is not a part of the type 1 machine.

The circuit breaker is to protect your compressor most times the its a problem by to less oil inside because of fall over during transport or operate with the powerplug instead of the pressure switch.
Than it has no pressure release and can not come to turned round
he needs to blow off by pressostat (pressure switch)before it can free start , BUT it can also happens that your capacitor is broken then there is no start direction and then there is also no start only humming sound

The start capacitor on the motor is bad. Replace it and it will stop activating the thermal cut out.

That is the compressor's holding capacity 150psi. Therefore, the cut-out pressure has been reached. The safety valve opens to relieve the excessive psi. Compressor should come on at 120 psi.

There are four screws that hold the end cap on the pump. The fifth screw at the bottom, middle of the cap is the oil drain plug.

Normally the value is about 10-15 MFD/400 Volt.

If the in-tank check valve is leaking air back into discharge line from the pump, the motor will not have enough power to overcome headpressure. Easy test with some air in the tank. Remove the discharge hose at the brass check valve at tank. Spray soapy water on valve to test for leak. If leaking remove the valve and clean the seat or replace as needed (drain air from tank before you remove the valve). If no leak at the valve, test the capacitor(should read to within 95% of mfd rating). Good luck
