Where Can I Get A Manual For A Sears Kenmore Super Deluxe Vintage Electric Sewing Machine Model Number C877.15?

I just recently took this model from the original owner who was just giving it away  because they bought a new one,  the electric plug was burnt out on it, so my electronically inclined bf cut the cord in half introduced a half of another cord with a plug on it an it works like a charm, I also have the complete manual for this model c877.15  the only thing I'm having issues with is knowing how to put the thread up near the needle-
if you still need help in knowing what the complete manuel holds I could scan it 4 you an email it to you.
