I bought this tool with the tire maintenance kit for $49.99. The price is much cheaper than my Craftsman HD impact wrench and my CP impact wrench. Just don't know whether this wrench is powerful enough to handle wheel nuts or not. I had to overhaul this wrench with the trigger valve and spring, and added oil into the hammer chamber. There was no oil inside the hammer chamber when I took out the oiling screw. I also had to tighten the screw at the forward/reverse valve at the neutral position. Once I fixed these problems, the impact wrench works fine. What is the hack, I wait for Christmas when the price drop back down to $24.95 to get one more. If I can overhaul and fix the problem, it is a good tool for occasional use.
In short, this gun "could" be a good gun however it starves for air. The trigger mechanism doesn't open the valve up enough - I played with it for days - I'm an Mech Engineer with a PhD and real hands-on experience - I know how to design and build tools - the valving mechanism on this just starves it for air. As a test, take out the air inlet valve mechanism by 1- remove the inlet port (don't drop the exhaust silencing balls) 2 - pull out the spring and valve Now put the inlet port back in - hook up to your compressor. I found it has considerably more torque now. That's the easy part. I also found that the air into the air motor is restricted by poorly drilled holes. There are slots in the throttle control that don't get air because of misalignment of the air inlet hole and the throttle control body (control switch on back).
Bought the combo package 26 gal air compressor w/ air ratchets, within less than a year with minimal use I just had it the air rachet replace. Sales rep at Sears said there notarise for going out and recommend to upgrade to the pro series. Air compressor and the other rachet works great so far.
this impact has the torque I need to loosen or tighten bolts & nuts in my garage I would recommend this product to all my friends
I would defiantly recommend this product it's very good and worth the money
works great but really needs a power adjustment for forward
Just bought it to use with a new compressor and hoping for good luck - inexpensive and it says Craftsman - hoping they vetted it and it works!
Not 400 torque it says to be
