Question about Hitachi Air & Gas Compressors

2 Answers

Motor will not start under load, but will start from empty tank.

I suspect that the problem is that this 2HP motor is not capacitor start, and as not the original motor i just need to check the correct size and rpm speed of the motor, the one fitted is 2HP and 1400 rpm, Does anyone know the volume of the tank and the rated CFM?
Thanks in advance
Paul

Bad check valve allowing air from tank back to the pump which when trying to restart has all that air pressure in pump cylinder pushing against the pump piston and with this load you will end up burning the motor

How can i fix my ec12 hitachi electric air compressor


This problem is caused by either the starter capacitor or the in-tank check valve. Ez to check. With no air in tank, start compressor; if motor hums or has difficulty suspect capacitor. If motor starts, partially fill tank and unplug the power. Check for air leaking at the pressure switch or air coming out of the air inlet (remove the air filter). If air leaking, replace check valve. If no air leaking, again let out all the from the tank and connect power. Allow the compressor to fill and shut-off. After the compressor fills, again listen for air leaking from the pressure switch unloader valve. If air continues to leak from unloader, replace the check valve. Good luck

Most people recommend replacing the motor capacitor in this situation, since a faulty cap will reduce the starting torque. But in my case the check valve was the culprit - there was too much back pressure on the head.

My 4 gallon 2hp unit will not start on its own and then the circuit breaker goes. I need to assist it to get started. Any ideas?


Check the tank check valve where the pump output line goes into the tank. If it's stuck open the pressure on the head won't be released and the motor will have to fight the tank pressure every time it tries to restart. Another possibility is the start capacitor on the motor may have gone bad. Only way to test it is to replace it.

My Clarke AC2001 4 Gal. compressor hums when power button is up. Compressor will not start up! Why?


one of a few things possible, first is that the start capacitor is faulty, second could be the start switch inside the motor, and the third that the pump is not unloaded ( if only happens when the tank has air in it) or the pump and or motor is locked up.
