We had one way back when, but I don't have an owners manual any more. Sometimes they will put the volume on the case of the engine, near the filler hole. You might want to look around. Also, that engine has a glass port where you can see the oil level all the time (why doesn't everybody do that?), so I would just add oil slowly and watch for it to appear in the window.
