I have a Hitachi C10FS miter saws that I bought new several years ago, and it has been an awesome tool! However, the other day, I attempted to cut on a piece that had a slight warp in it, and the saw jammed. breaking the left hand cover (p/n 310-688) into about 50 pieces. I called Hitachi Customer service, and was informed that this is an obsolete saw, and that no replacement parts are available. So now I guess I own a $750 green anchor. Unless someone out there has a saw that has failed, and they are parting it out. I guess there's a possibility that one of the authorized svc centers may have this part in stock, but I haven't found that one yet. If anyone knows of the whereabouts of a part like this I'd sure appreciate any info. Thanx.
