I did a search with your description,
manual for a Kenmore 10 stitch sewing machine model 158.13500. I found numerous places to purchase your manual. I'll give you two answers; there were more sites, though. You can put it in your search engine and pursue the most cost effective place.
It appears to have numerous pages, which would be difficult for someone to scan and share.
This one might be free, it might also be just a parts manual:
