Just bought a Yanmar B50 and I am a total novice. To start with I need an Operator or Service manual so I'll know about checking and changing fluids and fliters. Everything about the unit seems to work but I don't want to start in trying to learn how to use it until I know how to do a basic service check. I see that there are B50 50-1 50-2, then A B. All I know is B50. Thanks for any help. LWINCHES@FRONTIER.COM
