SOURCE: I got a used Hitachi ec12 compressor, it doesn't start.

1.Check the motor first. You can readily see if it's
burned or not. Run a megger test on the motor.
Test run the motor without the compressor.
2. If, it does not run, have it checked at the motor
rewinding shop.
3. Once it is okey, remount the motor, and start it up.

SOURCE: Hitachi EC12 plug it in and nothing happens. No

Sure the outlet you plugged into is working, do not use an extension cord.

If there is power, then there is a black box, where the cord enters the unit., in here is the pressure switch, it tells the unit to work,
unplug the unit open it and see if the plate with the spring moves freely
and then try it again, if not you probably need a new one, I would contact
the company and see if there are problems with the unit and see what they will do for repair, or they might have a better option for troubleshooting this unit.

SOURCE: I have a Hitachi compressor EC12. Sometimes when

Could be the return valve. Its the small fitting that attaches to the top tank. Unscrew the top nut its about 11/16's, with no pressure in the tank, and make sure the black rubber seat inside slides in and out of the spring loaded cap, easily. If not, sand the rubber until it does slide easily, then apply light oil, to the area you just sanded and re- assemble.

My engine is makinng a clackin noise when i start it but when i press the gas it goes away but when i stop a light or something it makes the oise again


Sounds like the oil pickup screen is clogged causing low oil pressure at idle. Oil pumps do not go bad in these cars.

Hitachi EC 12 2hp Air Compressor. Just get a buzz sound when plugged directly into 120v wall outlet. Piston and shaft turn freely. Have installed a new pressure switch. Just turned the compressor on...


Hitachi EC12 Air Compressor Parts : MASTERTOOLREPAIR.COM

Here is a site that says:
1. Are the capacitors good? (They get the motor going).
2. If they are, replace the stator, ($245)

If you don't find a good solution there, I would try taking it to a local motor rebuilder.

I started my air compressor for the first time without any oil. Now it makes a buzzing noise. Is there a "simple" solution other than replacing the motor?


Running compressor without out oil generally will damage rod and deposit metal on crank lobe. Metal can be removed using 400 grit sandpaper cut into one inch strips pulling back and fourth untill lobe is clean as new. You will only need to buy the rod(about $20) and one sheet paper. Remove pump/motor from frame, remove two bolts holding cylinder to body and airline and pull up on cylinder to expose piston/rod. Usually the rod will slightly coat the crank with metal and seize. Remove or work rod off lobe. Clean crank area and add fresh oil. Parts available at www.toolpartsdirect.com Good luck

My Hitachi EC12 builds pressure, shuts off, then air escapes


I have the same compressor with the same problem. I have temporarily eliminated the thermal reset with a piece of 12 gauge hard wire and it runs just fine. However, I do want to replace it before the warm weather come to the north. I tested the draw at 15.5 amps and the reset was a 17 amp. I am told by someone with superior electrical background that I need to install a 20 amp thermal reset in it's place. I have found that mine runs best when plugged directly into a 20 amp circuit and when using an extention cord I have a 10 guage cord that will carry the load needed to run the EC12. I have also changed to 100% synthetic oil.

No air pressure at the hose


It sounds like you have trouble with your pressure regulator. Make sure that the knob for the regulator is turned clockwise to increase pressure. If this doesn't work, you may need to replace the regulator.
