Help I have just inherited a Huskylock 234D and I can not figure out
how to thread it. I think my problem is in the lower looper. Can
someone please offer some suggestions?

Thread the upper looper first, following the chart inside the door.
Then the lower looper, but when you have the lower looper threaded make
sure the thread goes over the top of the upper looper and sits in the
little notch. (This is the most common mistake). Then thread the
needles. Pull all threads under the presser foot and to the back of the
machine.
