Breadman is just one brand name of many products made by Salton ... their website is here
. They should be able to help you obtain another copy of the manual for your particular model breadmaker.
I've never heard of using a bread machine to make jam - so I can't give you any advice about that. You would really need to read and follow the instructions in the manual. I'm guessing that if you want to make jam/jelly/preserves, etc. in any quantity you'll be better off with a 6-qt pot and a wooden spoon ... and do it by hand like your Mom did.
Now, as for canning and preserving that jam ....
Alltrista Corp now owns Ball (who makes the "Mason" jars) and Kerr (who makes the lids). They have a website
with a lot of information covering the basics, and you can buy IMHO the best basic beginners primer for home canning (which includes TNT recipes), the Ball Blue Book
for about $5 from them.
Another good site worth visiting is The National Center for Home Food Preservation
- which is a co-op extension program of the USDA.
