Part is available here :http://www.toolpartsdirect.com/cgi-bin/schematic.cgi/hitachi/EC2510E
Factory part is very expensive.
If you are good at plumbing you could use a generic unloader for about 1/3 of the price, available at www.grainger.com The generic valve has 1/2 npt female threads on both in and out ports. Good luck

Pressure off and on every few seconds with my karcher 3000BH


hi there rjcomer2

here is web site for parts
http://www.ereplacementparts.com/karcher-2500-11944010-pressure-washer-parts-c-33388_33389_33973.html

sounds like you have a unloader valve problem or a crack in the pressure manifold housing between pressure outlet and unloader valve assy allowing unloader to cycle on/ off

or some dirt trapped in the unloader valve seat , make sure you have good supply of water - ie good flow from tap to pump

try cleaning unloader 1st and fitting in line tap filter

hope it helps

Can i use a impact wrench with my hitachi ec2510e gas air compressor


Yes, but it may drain your air supply quickly and you might have to take little breaks and wait for it to fill up again.

Motor will not crank when air is in tank.


you are supposed to use the unloader valve to start. when air is in tank the starter motor is not only turning the motor but also trying to compress air. this very hard on the whole unit. the unloader valve should have what looks like a loose lever. lift the lever and it pulls the attached rod. after motor starts and runs put back to rest position

Attwood RV Water heater model GC6AA-10E overloads breaker when


I would remove the heating element from the hot water tank. Take a look at it as it is probably fried from due to turning on the power to the tank when there was no water in the tank. If it looks ok still do a continuity test on it. I believe that is your culprit.

please mark this answer as a fixya!

Gas air compressor shuts down


IS IT BUILDING TO THE UNLOAD PRESSURE AND THEN STALLING OR JUST SHUTTING DOWN ANYTIME. IS THE UNIT SITTING AT AN ANGLE?

DOES IT WORK FINE WITH THE LOW OIL SWITCH UNPLUGGED? UNPLUG SWITCH AND LEAVE IT UNPLUGGED FOREVER.THEY'RE ALL P.O.S.
