air impact wrench
Have an air impact wrench it only worked twice from new then stopped.When trigger is pulled its leaking air at forward/reverse button and not working.Have stripped it apart and cant see anything obvious.How do I get forward/reverse button out to check o ring.Any other ideas would be great.Conan

It`s about 2 years old and only used 3 times.It should be under warranty but shop is saying I need to have original purchase reciept to get the warranty.The model is a power craft.I have parts diagram and think if I could get forward/reverse botton out, the o ring could be gone,have had everything else stripped out of it.Conan

Yeah, I can believe that. Repairing such things is not my area of expertise but it sounds like you're on the right track. Others should be along with greater knowledge than I have.

Have you properly lubricated the wrench with light oil down the air pipe, or in the oil hole on the side? It may just need some help getting rejuvenated. Oil will also help keep the "o" rings softer and prevent premature cracking.

Fully lubricated when I pull the trigger the oil flies out all over the place because the air leek is pushing it out.When I strip it apart parts are good and lubricated.Conan

heres what you wanna do.
open your gun up and first thing you should see is a gasket. take itoff and then you should see a bearing. take that off. then you should see a cylinder with slots in it containing blades almost. take all of them out and THOROUGHLY clean both the blades and the cylinder its self. (this cylinder is actually a motor). when air comes into the gun it passes through 2 a whole load of stuff and into this cylinder (or motor). these blade like things (don't know the name for them) are always flapping around to catch the compressed air therefore turning the motor. but if these blades are even the smallest bit seized then you have a problem. they won't flap around and won't catch air which means you will have a non working gun.
hope this helped

The manual says the valve is defective,does anybody know where the valve is.I have a parts diagram and only valve showing is in the forward/reverse button is this what they mean.Conan
