First of all, here is the main Singer ONLINE SUPPORT AND DOWNLOAD page for your model:
http://www.singerco.com/accessories/manuals.html
To view the Support Page just use your mouse to click on the link, which is the underlined and highlighted text just above. This will open a new web browser page automatically for you and allow you to view the information at the website indicated. Then type 2250 into the empty search box on the lower right hand side of the page and then click on SEARCH.
To download the Owner's Manual with operating instructions, just click on the FREE DOWNLOAD! button on the right hand side of the Singer support page for your model when you get there. Then when it asks you if you want to open or save the file, click on SAVE. Then choose a place on your computer to save the file like on your DESKTOP so you can find it easily later. Click SAVE and once the file download is complete, then click OPEN and you should then see the contents of the manual.
You may need ADOBE READER installed on your computer to read PDF documents. You can download this free at
WWW.ADOBE.COM if necessary. Click on the DOWNLOAD ADOBE READER button on right side of the ADOBE home page when you get there.
Please comment back here to this page if you have any questions, have difficulty accessing the links, or just require further general assistance and I will respond as soon as I see it.
Thank you very much and good luck.
