... rated @312Nm (cheap I know) with a 3/8 line with 1/4 snap on adapters each end and it just seems like there is no power to it, it wouldn't budge my lignum and it wouldn't even undo the wheel nut on mu compressor wheel, cam anyone advise me on what the problem may be, I thought the gun would be sufficient enough to remove a wheel lugnut and thought the compressor was powerful enough but any advice would be welcome thankyou.
