I took it out of the box put in a metal cutting blade and 30 minutes into cutting up metal sheeting it lost all its power to cut because I had purchased it from Amazon. com I had no where to return the brand new saw. I took it to a Milwaukee service center. I went to a pawn shop and bought a $60 sawzall and finished the job I had to complete. 2 weeks later I got my brand new sawzall back. I keep using the pawn shop specail because it works and driving back and forth to the repair shop wastes alot of a day.
