Serpentine belt tool kit. FAIL! I almost punched the front windshield out of the car i was working on when one of the crowfoot wrenches broke the first time i used it. HUGE FAIL
I use a IR2135qtimax with my compressor. My home compressor is on its last leg 15 years in. New it claimed 3.8cfm at 90psi. Even with 1/4" line and fittings it'll still break loose any bolt I've hit with it. It's got to be a problem with the gun. Keep us posted
