My impact wrench when connected to the airhose stay on even though the trigger isnt pressed

Yes, if you take it apart you'll find that the trigger isn't allowing air to pass through to the veins of the impact wrench. It's a relatively simple mechanism, where maybe something is broken inside.

If it were blowing air but the veins were stuck, I would say, lubricate it. But, if no air goes through it at all, then the trigger housing houses the problem part.

Have you tried to disassemble the air wrench?

i have the same problem, and a fellow co-worker of mine told me about the problem. here it is.. on the handle there are two slots on either side, push them in and the air inlet assembly should pop out along with a broken tiny metal rod.. this rod connects to the inlet valve and turns on and off ur impact wrench.. i have been looking for replacement parts but cant find any.. hope this helps you and maybe help me too..

has it been oiled was it oiled when you took it apart things to check for also does it have a adjustable torque on it

try lubricating it with air tool oil, put ten drops in at the air nipple, try tapping unit on table as you press trigger in and out.

The problem is in the trigger valve and is a very common problem with these and other brand, some even do that when new! Most people just live with it but you can dissassemble the gun and try.

if air sound comes out when you press trigger your pressure regulator pin is stuck-oil gun and attach hose repeate until pin frees or remove pin and clean with brake kleaN oil and replace

jb weld it

I have ran into this many times, even though you keep it oiled dirt can and will get inside. what you need to do is unscrew the 4 alen head bolts and pull the nose off. You will see a shaft that looks kind of like a crankshaft with 5 or 6 flat carbon fiber plates sitting loosely in groves around the shaft. pull those out and clean them with solvent and check them for damage or wear. clean the inside of the gun with solvent or brake cleaner, reassemble and it should work fine. If the plates need replaced then you should be able to order them from a tool supplier,and they are not that much.

An impact wrench works in the manner suggested by the name of the tool: through the principle of impact. In order to understand how an electrical or air-powered impact wrench works, it helps to know first how a manually powered impact wrench operates. A manually powered impact wrench looks like a fat screwdriver; on the end where the screwdriver blade normally goes, you can snap on screwdriver bits or sockets.
