1/2 air impact wrench will not turn socket. Air just comes out the small vents on the bottom of the handle. Any suggestions?

Sounds like you might have an issue with the air inlet assembly (item# 26) at the very top there is a o-ring that is susceptible to wear (item # 28B) but it only comes in a repair kit p/n 2315-k303.
Removal requires a special tool p/n 2131-322 to depress the inlet clip (item # 27) to be able to slide the assembly out, but two small flat blade screwdrivers could be used as a substitute.

I put some lubrication oil into the air line then made sure that it goes in there by moving the anvil (1/2") back and forth then tapped the lower handle making sure the oil goes everywhere. it worked on mine.

If debris enter the gun, over time the vanes will not move into proper positon and react to air-flow. Vanes can become stuck if stored for long period of time. Pour small amount of diesel fuel into the gun and activate the trigger. The fuel should come out clean, if however black gunk comes out, keep adding fuel until gun is clean. Eventually all the the debris will be washed out and restore function. Good luck

get some air tool oil and put it in the hose connection and manually turn the socket end by hand,the air vanes have frozen in place and can't hold the air in to operate the unit,make sure when you do this squeeze thge trigger to let the oil into the units barrel,then connect to an air supply and try it,you may need to help get it started by hand,then let it run and add some more air tool oil again to keep it lubed

Make sure the expansion ring is on the end of the impact gun. this holds the sockets in place.

I just bought one of these also. Manual says oil goes into "the air inlet" which I'm thinking is where you attach the hose. That way the oil is sprayed throughout the interior of the gun once you run air through it.
Question for you: I can't get an impact socket onto this gun, almost seems like the square hole is too small. (yes, both are 1/2" drive). How do you get a socket on this stupid thing?
(man that sounds like I'm an idiot, but I've spent a half hour leaning all my body wight, wiggling, etc. and can't get a damn socket on)

Hi there,

There are times when there is no substitute for air tools, specifically an impact gun and sockets.

However, chances are you won't be able to get one down in there, so this might not be one of those times. Breaker bar with a pipe over the handle for added leverage.

Treating it with penetrating oil can't hurt either

Good luck
Mike

typical ---get it serviced there is small platic type o/ring on trigger in the handle that gets brittle and breaks up,mine went just after easter ..make sure ,when fixed to add a few drops of transmission fluid to th e air inlet every time you useit

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.

An air-powered impact wrench runs off of an air compressor with a tank – the air compressor should have at least a 10 gallon tank and be able to generate at least 3hp. Also, an impact wrench requires special sockets that are designed to withstand the high torque applied by the wrench.
