SOURCE: 1/2 air impact wrench will not turn socket.

Make sure the fitting are tight on the hose and gun. Also make sure that the switch for forward/reverse is solidly in one position, if it is not it will cause what you described.

SOURCE: Craftsman 1/2 inch impact wrench,not working

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 ...

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)

SOURCE: Why doesn't my craftsman air sockets not fit

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

How do I determine how much torque my impact wrench makes?

I test my impact wrench on a good vice and with a high grade steel nut/ washers and bolt that can take high torque. Select bolt with thread almost to the head. Hold head of bolt on solid vice and place two washers(more if needed to reach into threaded area) and nut on bolt. Set air pressure to max (I have 125psi). Run nut against bolt head with impact. Remove nut with torque wrench for reading. This low tech method will give you a rough idea. Higher pressure may give you better result. If you have used your air wrench for a while. Clean by adding diesel fuel into air fitting. Little at at time until diesel comes out rather clean. Then add a few drops of oil. Then test again. Good luck.

I have an old craftsman impact gun model number 875-188992. what size compressor do I need for taking off lug nuts/automotive work?

The two most important specs are CFM at 90 psi (that's how fast the compressor can compress more air when the tank starts to run low) and how big the tank is. Virtually any compressor that has a top pressure rating 20 psi higher than you need for your tool (which is usually about 90 psi) and that has a tank of a couple of gallons will work. But the smaller the tank, the shorter time you can operate the tool before the compressor has to kick in. And the lower the CFM at 90, the longer you will have to wait for the tank to come up to pressure again so you can operate the tool at full pressure. If this is for occasional use and you aren't in a hurry, you don't need much of a compressor at all. If you want to operate continuously, then you should get something with a CFM at 90 psi that is higher than your tool's CFM consumption. Keep in mind that impact wrenches don't operate continuously like paint sprayers do. Good luck. Vote if you found this helpful. Al K

Where do i get a replacement trigger, mine is

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.

Put 4 or 5 drops of oil into the air line opening. Connect an air supply and burst the trigger a few times. The settings are 1-less 4 more. It's all up to the application and they are not specific settings.

Electric impact wrench runs slow with no power

ALL Sears products have the replacement parts listed at;

Enter you model number and you will get a diagram and parts/price list.

The people at Sears should have known that. Sears also have free-standing hardware stores in many areas.
