Bought an impact wrench to easily get a Flywheel off my Honda crf250r. I am kind of a newbie mechanic, never used an impact wrench before. Worked great! Way easier than trying to hold the flywheel still while trying to muscle off the flywheel nut. Anyway, I bought a Crapsman (I mean craftsman) 3/8 drive impact wrench. Why? Because it was cheap and did not think I would be using it that often. I cranled up my Porter Cable do it yourselfer pancacke style 135 psi compressor. When it got up the wrenches recommened 90 psi I turned it off. I noticed what while not using the wrench there was a hissing coming from it and it turns out is leaking air slowly. Came back out after eating and the compressor was emty down to zero. Is an impact wrench supposed to slowly release air as some kind of safety measure or did I get what a paid for - a crappy impact wrench?
