Question about Hitachi EC12 Portable Electric 2hp Air Compressor, Oil Lubricated

3 Answers

The air tanks fill with air, but the pressure

The compressor turns on fine and motor runs fine, motor shuts down at 120psi. The air tanks fill with air, but the pressure guage doesn't work and no air will come out thru the regulator into the hose. Any ideas?

Take the knob off there is a spring in it with a black plastic part. Most likly this is broken, look for it on eBay.this piece pushes in and opens the regulator.

SInce the pressure gauge is not working, replace it. Also remove the regulator and clean it. Be sure to unplug the compressor and drain the tank before you start.

The regulator sounds like it is cranked closed. Try slowly operating the adjusting knob in the opposite direction. As the valve moves, you should see the pressure rise on your gauge (it probably does work).
Hope this helps....now go make something!

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.

The air is coming out of the pressure switch but the problem is the tank check valve. The tank check valve is on the tank where the large line from the pump feeds into the tank. There is also a smaller line, either plastic or copper, from the check valve to the pressure switch. When the pump shuts off the check valve is supposed to close and the pressure switch opens a valve that lets the head pressure bleed off through the small line. This lets the motor start the next time without any pressure in the head. If the check valve isn't closing properly the air will leak out as you describe.

I have a central pneumatic aircompressor with a 21 gallon tank.It pumps up to 120psi then pops off down to 80psi and goes back to 120psi...back and forth... never stoping...could it be a bad pop-off valve?


I would first find out what pressure the compressor is supposed to shut off at. If it is supposed to shut off at lets say 110 then the pop off valve is doing its job you have to reset the pressure switch so it shuts off less than 120 pounds.

My air compressor won't get past 60psi but keeps running and isn't leaking air anywhere when I shut it off


Your problem lies with the valve plate and/or piston & cylinder. If one or more reed valves on the valve plate are cracked, bent or broken; pressure will only build to a certain point. If either the ring on the piston is damaged or the cylinder is badly scored it will not be able to compress air beyond a certain point. Unless the tank pressure reaches 120psi to 130psi the pressure switch will never turn the motor off.

Can not build working pressure pressure......


The most likely problem is a burned out "run capacitor" on the motor. If you continue to try to run your compressor in this condition it will burn out the "starting capacitor" and/or motor as well.
It's also possible that you have a bad start up pressure relief valve, this valve will be between the compressor and the tank. If this valve is working properly you should hear a hiss of air as the compressor motor shuts off.
A reasonable motor repair shop should be able to replace the run capacitor for $20-$50 plus inflation, depending on your area.
If you need to test the start up pressure relief valve, you need to take it loose at the compressor or tank. Just loosening the line may not work depending on the style used. Note: sometimes just taking this loose to test it causes you to have to replace the valve.

My 33 gallon air compressor will at start build up to 120 psi and shut off, after use and at about 80 psi the motor tries to start but kicks our circuit breaker? Any help would be greatly appreciated!


Most likely it is the unloader valve. This is inline with the air filltube from compressor to tank. Somestimes the unloader valve is screwed into the tank and air tube is attached to it. This device takes the pressure out of the tube so the compressor can start without the back pressure from in the tank. Other possibility, the start capacitors of the motor. The capacitors must give a kickstart upon startup or the motor will just hum for a couple seconds and overload the breaker. A tempoary solution is to turn off the power to compressor when it reaches 120psi, then allow the pressure to drop to 40 or less, then turn power on and mostlikey compressor will start with a load of 40psi or less. It is a nuisance but it works until you replace the bad part. Goodluck,Macgivor

Champion VR7F will not restart without hitting reset switch.


Solved this problem. It required a new motor starter (or at least one component from the starter. The main power lead running to the thermal overload relay had oxidized and was conducting current poorly. Each time it would run ( I did this with the motor starter cover off) the lead going to the bottom side of the thermal overload would spark then glow red during the tank fill. I removed the bad section of wire, and installed a new thermal overload in the starter.

Starter valve dont close hatachi ec119sa (air compressor)


The start valve gives your motor a running start before the motor begins to load as the pressure increases from an empty tank. The motor strain is more profound when there is pressure in the tank. If you plug the valve, the motor will instantly encounter a heavy load because it has to force air into a partially filled tank. This extra load without the valve will shorten the life of the capacitors and motor windings. There could be two problems with your unit that can revealed by test. What actually closes the valve is a certain volume of air produced by the compressor. If the compressor is not pumping to full efficiency or there are leaks in the discharge hose the valve will not close. Or the valve is faulty. With an empty tank, plug the valve and run compressor and test airline for leaks with soapy water. If no leaks, empty tank of air and restart compressor and take note of the amount of time it takes to fill the tanks to shut off. If it takes an unusually long time to fill, then the compressor probably has valve problems causing low air volume. If the compressor fills to shut off in a short time frame as compared to a similar model then replace the valve. Leaking valves in the head will also cause the pump and discharge tube to run very hot. Parts are available at www.toolpartsdirect.com Good luck with your repair.

Air compressor fills, but slows down as the pressure builds


sounds like you need a new check valve which should be somewhere between the compressor outlet piping,tubing,etc and the tank which prevents the air in tank to back feed to the compressor which would cause hard starting and could damage the motor easy way to check is when you shut off the compressor with some air in the tank if the check valve is bad it would continue to bleed air out out the unloader valve .the unloader valve on your unit is most likely part of the pressure switch when the unit shuts of it should only bleed down the pressure in the pump so it would make it easy to start when needed hope i didn't confuse you
