First of all, here is the main Singer ONLINE 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.
To download your Owner's Manual, just enter 6510 in the empty search box on the lower right hand side of the support page when you get there, and then click the SEARCH button.
On the ensuing page, click on the red FREE DOWNLOAD! button on the lower right hand side of the page beside the 6510 6550 - WORKBOOK - SCHOLASTIC and SCHOLASTIC PLUS WORKBOOK - ENGLISH - HOME - FREE! option.
When it asks you if you want to open or save the file, choose SAVE, and then select a place on your computer to save the file, like on the DESKTOP so you can find it easily later. Then click on SAVE.
Once the file download is complete, click on OPEN, and then you should be able to view 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, and then just follow the onscreen instructions to install it.
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.
