Pneumatic tools are rated in cfm (cubic feet per minute). Your 1 HP air compressor is rated at probably not more than 3 cfm while the 1/2 " impact driver needs at least 8 cfm, maybe 12 chm of air.
The compressor must provide more chm than tool rating needs.
It is a problem, by the time you look at five horse power air compressors and larger, a lot of electric power is needed. A circuit of 220 volts, 20, 30, or more amps would be required to run those large expensive compressors.
If you can, return the air tool and get a good electric tool instead.
Leave those high air volume air tools to shops that are so equipped to use, or invest if you must.

SOURCE: craftsman 1 gallon direct drive oil filled wont build air pressure

It sounds like you may have a broken reed on the diaphragm plate. This is located at the block. Remove the cover, and look for a cast metal assembly with fins. It will be attached to the side.

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

Im going to buy a compressor ! What is the min scfm comp that will run this tool for small jobs on my car?


Hi and welcome to FixYa, I am Kelly.

Air Tool consumptions are based on 15 seconds per minute (25%) of tool use.

Usage rates refer to the total time that air is flowing through the tool. If your applications result in more extensive usage, calculate air tool requirements as

follows.


(25%) 15 seconds = rated scfm x 1

(50%) 30 seconds = rated scfm x 2

(75%) 45 seconds = rated scfm x 3
(100%) 60 seconds = rated scfm x 4

Your impact wrench is rated a 8 CFM Cubic Feet Per Minute Usage

SCFM is Standard Cubic Feet per Minute (pre-compressed air volume)

I would be more concerned that the plumbing from the compressor tank could support the 8 CFM required by the 1/2" Impact. Remember the Air compressor will recover the pressure loss regardless of size. The only problem your going to have for "small jobs" is if you use too small of an air line to supply the impact wrench you are not going to get the full torque that it will produce to the drive head. In other words... a 1/4" supply line or 1/4 fittings anywhere in the system just isn't going to cut it even at 120 PSI. If you have the patience... a 5 gallon tank compressor that has the output volume required should be all that you need. I have been a mechanic over 4 decades and rarely have to use a 1/2 in impact for very long. Examples of 1/2" vs 3/8" useage. Wheel nuts, crankshaft pulley center bolt, some starters, steering, suspension and rear end parts. Other than that a 3/8" Impact works great.

One other thing you can do if you have an Air-Peen portable tank (with added fittings) is to add that in line with your output hose when your using the impact wrench so that you have longer use times.

I know this does not answer your what SCFM compressor is required question but it will resolve your needs. I just can't see telling someone that is a "small jobs" user to buy a larger compressor when really all they need is more volume for a brief period of time. The re-plumbed 1/2 inch output / in-line Air-Peen tank is a much cheaper and reasonable work around and you can disconnect that tank when your not using the impact wrench.
Lastly... if your inpact wrench has a SMALL male air fitting everything above will be a waste of time. You have to get that volume into the tool without restriction so that the rool will work properly for you.

Thanks for choosing FixYa.

My brother passed away and i was left his tools. I have a Craftsman Model 875-71229 Air Impact Wrench, but no manual. I do use tools, but as I'm not a mechanic, I was thinking its probably of no use to me,...


The Chicago Pneumatic air wrench is not the same as the Craftsman, but it's a good brand.
Probably you could sell it if you have no use for it yourself. The impact wrench would have been used to remove lug nuts or other fasteners on an automobile, most likely.

Good luck on deciding what to do with the items.

An impact wrench also requires a few special accessories. 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.
