Some of you may have already found a copy of the Service Manual for the 3YM20, but for those who haven't please follow the attached link. They ask you for a brief review of your opinions on the 3YM20 befor allowing the download. This is a large 15MB PDF download so allow for some time if you don't have a highspeed line.
