While this saw is running and I intend to keep it - BUYER WARNING: There are two main issues to be aware of: 1) The screw holding the disc is unique - it rotates counter-clockwise (counterclockwise). clockwise). to BOTH screw it off and screw it back on! I know there is a small sticker on the saw to indicate this, as well as a picture in the instructions, but I had to call the company direct to find out! IMHO they should put some kind of "Read First" sticker on the screw so you notice! 2) Since the body of the saw is in your field of view, it's VERY difficult to cut straight lines! I used this saw to cut a 12 foot profile into what I thought were the same parts, but the results were very disappointing! which I plan to use for precision cutting in the future instead.
