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

1 Answer

No air pressure at the hose

Ec12 twin bottle has the gauge which measures pressure in the bottles. Second gauge regulates pressure to the line. It reads 120 and bottle read 120. Plug a tool into the end (bypassing a hose to rule that out) and when the trigger is pressed the needle drops to zero on the line gauge and a small puff of air comes through the tool. Once released the gauge rises back up. ???

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.

Ec12. Runs fine. Tanks fill fine. Just run out of air when using large volume items. i. e. framing nailer, filling tires. Like its taking too long for air to get from tank to end of hose. Almost like there...


You are correct in suspecting the regulator. Easy fix however. Remove the safety pop valve and install a tee fitting. Reinstall the safety on one port and install a quick-connect fitting on the other port. Now you will have access to full tank pressure when you need full power. In the process of regulating pressure, the 1/4 inch port size adjustable regulator will restrict the air volume. A 3/8 port size (larger air regulator ) is less volume restricting however more expensive. You can install a 3/8 port size regulator on your compressor in place of the small one installed now. Other possible trouble areas are too small inside diameter air hose , too long of a hose and air hose that has inner liner torn and is restricting airflow. Good luck

i assume your are talking about the pressure regulator. if it won't adjust to raise and lower the outlet pressure it is broke. you will have to replace it with an in kind type.

I can't adjust these gauges. How do I do it?


The only part of the gauge that adjust is the tee handle in the middle. the gauge on the left tells you the line pressure to the torch, the gauge on the right tells how much oxygen is in the bottle, usually on a K bottle it is 1800 to 2000 lbs. if you turn the tee handle and the left gauge that tells line pressure does not respond you probably have a bad diaphragm in the gauge. Seek qualified repair man. Thanks

My hitachi EC12 compressor starts up and fills the two tanks. When I connect my hose, the pressure in one tank drops to zero, then goes back up to about 60 psi, then very slowly builds back up to max...


how do you know one tank drops to zero unless you have a pressure gauge on both tanks sounds unlikely unless you are looking at the gauge on the pressure regulator

The air tanks fill with air, but the pressure


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!

No propane flow to grill using bulk bottle system.


the office that is open on the bottom of the burner sound like a spider has taken home to.. the hole.... This happened to mine. a small pipe cleaner or wire will break it up...try that. also did you feel the top of the tank regulator and see if it has froze. try turning the tank upside down and turn the unit on.... this may also help by forcing the spider debris out.

hook up the gauges to the large line at the condenser, press in contactor, place ref can in hot water or at least water. the hoter the can the higher the pressue, dont use a torch. with the unit running the will be less than 65 psi at that low sidevalve. Outdoor pressure should be 200-285.
