when the typewriter is first switched on the typewriter will automatically set a margin 10 or 12 spaces in,depending on which pitch setting you have. To set a margin say on 20,space-bar in to 20 on the spacing scale and then press Margin Set Key. to set a margin on say, 5 first depress the Margin release key and back-space 5 spaces in and then set then margin as before. Remember that the typewriter will "forget" the settings as soon as it is switched off.
