Make sure you have at least 90 pounds of air and if you do you need to oil the wrench air tool oil pour some in the where the air line hooks up ..air tools need to be oiled daily cause compressed air cause water vapors to build up when you use it and then when it sits it begins to rust a bit and the oil stops this ...

Try turning your line air pressure up to at least 90 pounds
Most lug nuts are tightened to 85 pounds or higher

SOURCE: Dont know where to put oil in Craftsman 1/2 " Impact wrench

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)
