Tammy, the technique of pulling the bobbin thread up won't be in the manual. Here's how to do it:
Center the needle on the previous line of stitching, the line which I assume you will be continuing. Position it so there are about four stitches ahead of the needle; you are going to sew over them. For the first stitch, just put the needle in, let the thread go around the bobbin case, and pull up one loop. Pull the loop out so now you have two thread tails on top the quilt, each about 4 inches long. Carefully aim the needle and take the first four stitches - by using the hand wheel - right on top of those you already did. Then quilt as normal. Later, you can clip the two thread tales close.
The other option is to take much smaller stitches in that area, following the same directions, but with four stitches in the normal manner, I would expect it to hold for you. You could bury your thread tails, but I wouldn't bother. I've done this many times and never had a problem.
I hope I was clear, but if not, ask questions.
