Added 8 Jan 2018:
I did find a web page indicating one could download the user manual for your model HomeStyles sewing machine for free. However, when I tried it, it indicated I had to register (free) on the web site. When I went to the page to register, it required me to enter my credit card information. I went no farther, since by providing credit card information, I felt there was an opportunity for some scam (against me or anyone else who registered.)

Hello, Gertie -

If you check eBay.com listings for Sewing Manuals & Instruction (check on a daily basis), you may find someone selling just the manual for your machine. This is the link to the eBay category for Sewing Manuals & Instruction:
https://www.ebay.com/b/Sewing-Manuals-Instruction/41246/bn_7701794

If you check that category daily, choose to have the listings sorted by Newly Listed.

Also, I suggest you search the eBay category of Sewing Machines & Sergers daily, in hopes of finding someone selling your model of HomeStyles machine. If the seller lists the owner's manual with the machine, contact the her / him immediately through eBay and ask if he / she is willing to scan (PDF of JPEG format) or photocopy the manual and sell the file of the scanned document or photocopies pages to you. This is the link for the eBay category for Sewing Machines & Sergers:
https://www.ebay.com/b/Sewing-Machines-Sergers/3118/bn_7714181

I will keep on looking and add information to my answer, if I find anything for you.
