I have a Craftsman mdl # 875.199460 3/8" impact that will not run. you can press the trigger and some air escapes, but it does not attempt to run or turn. i have checked the inlet and no obstruction and also pulled the bottom plate to insure no obstructions. none found. i removed the rear plate, but did not go any further. the gasket seemed stuck and i did not want to destroy it. What do you suggest checking. the unit has very little use. it seems like the air stream never get to the motor. ask for more info if you need it. Please Help!

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)
you probably have rust and goo in the line and it has stuck the trigger open,run some air tool oil in and let it soak or better yet some penetrating oil to break up the sludge and then when cleaned out use the air tool oil to lube it
If your local Sears store can't help you, try looking to see if you have a Snap-On, Corn-well, or Matco tool distributor in your area. Many air tools are manufactured by companies who make tools for different distributors. I work in a shop, and have found that many of the tool trucks have parts that'll work on other brands of tools besides their own.
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 ...
there is a neoprene O ring in the trigger area ,that breaks down ,it needs a service by an air tool repairer ,it is not expensive. dont use wd40 or the like if dont have airtool oil use auto transmission fluid and this wont happen too often
