I have a (new) 3 gal 1.25hp Craftsman air compressor that I tried using a (new) Campbell Housfield 1/2 inch air impact wrench with....

The compressor works fine for airing tires, pool floats, etc.....

The impact wrench will not work when hooked to this compressor....it just hisses as if the air is just passing thru the impact wrench without engaging the wrench mechanism....

Is this because the 3 gal tank is not enough air volume to work the impact wrench...??

Is it because the 1.25hp is not enough hp to keep the air flowing at maximum flow rate...??
