This is a heavy rascal, but it works very well and since I have never handled a jack hammer that wasn't heavy, the weight is no big deal. It came with 2 tools, one pointed and the other a blade. You must fill the oil reservoir since they don't ship it with oil in it. Get it upside down in the daylight to figure out how the tool is installed. Then take it out and beat up some concrete. You will need to add a little downward pressure on the handle once you get it going. You will know when it is the right amount, the hammer will start going like it is supposed to. It made quick work of the concrete busting job I had wanted to do.
