More than I can understand??

I took the sewing machine out of the case! It is a Janome Quilting/Decor 4030 QDC How do I find the manual online for this machine? I also have a bunch of bags with many different gadgets, something that is still in a flat rectangular box and who knows what else. I purchased it before retiring and head it shipped of to this, my new place. I was shown how to work it, but do you think I can remember? You're correct, I cannot. HELP?
