I seem to be having a little trouble with my Dewalt DW057 impact wrench.... I'm not sure if it's one big issue or a couple of seperate issues... It's not getting anywhere near the torque output it should....... I haven't checked what it is outputting but I know for certain it is much less than 75ft/lbs for tightening wheel nuts on my car... When I use it it quite often will stop dead and not start again unless I rotate the 1/2 inch drive one way or the other... When I do this it will work again with a trigger press.... Sometimes when I press the trigger nothing happens requiring the same rotation of the driver as above... Given the value of the tool I'm a little reluctant to pay to have it repaired... Is there any way I can test the components to determine where the problem lies... I figure it can only be the trigger, motor, or gear/impact assembly... Or can any knowledgeable person tell me what this sort of problem is likely to be... I also have the DW056 & DW059 so I really would like to get this member of the family operational again! Any help much appreciated...
