The manual would be improved by the addition of a specifications page, but maybe we can estimate the capacity without it. The give two recipes for white bread. The "large loaf" is 1.5 pounds and uses 3 cups of flour. The "small loaf" is 1.0 pounds and uses 2 cups of flour. Several reviews say that it is quiet and a good solid machine.

The Oster 4811 seems to be what is called a "vertical pan" machine. From what I am learning "horizontal pan" machines are now more common and make more traditionally shaped loaves. These days machines are available that make up to 2.5 pound loaves!

The Oster 4811 has only 6 buttons (and an LCD screen with menus). There are start and stop buttons (easy enough). There are hour and minute buttons (not much chance for confusion). There is an "arrow" button to move through menu selections and a "select" button to finalize a selection.

When it first turns on, the arrow button allows you to choose one of 4 bread types: white, whole wheat, french, and sweet. After making that selection, you another set of 4 choices: light, medium, dark, or dough only. Then you get the option to select rapid (but if you hit the arrow key it cancels this and moves on to the next set of choices, which are "large" or "small". After this, you are ready to go and can just press Start to get going.

However, if you want to use the delay feature, you should use the hour and minutes button to set up the delay before pressing start. Note that the time displayed will be the time when the bread is done, which is a nice way to do things. Minute delays must be done to the nearest 15 minutes. There is a yellow delay button to indicate this has been activated.

The time display shows how long you have to go. The Stop button responds only if you hold it down a full second or so.

The Bread Machine Digest is a nice online resource.
