I got a Kenmore Md 158.1792280 in the dump. It appears to work but I
have no idea how to thread it. The bobbin is in and loaded already.
I
looked online for a manual with no luck so far. Can you help me and
give me an idea how to do it. I have an old American standard
machine I
have to hand thread. I assume that this Kenmore auto threads but how
do
I start that process?

I don't find a model number like that he

but under the Kenmore 158 column, they do list a 1792:

Not sure that helps.

Nor do I find that exact model number under the Kenmore list he

but perhaps you could send an e-mail to their contact: Sewusa1 [at]
yahoo [dot] com and ask?

HTH,
