Help please? I found an old Waring VJ-1 juicer at a junk shop. It's in great shape and seems to work fine. I am dying to use it but I have no manual for it and can't find one anywhere since it's so old. It has a plastic mesh type stuff around the inside and I have no idea how to use it?? The only thing I see missing is the plunger for pushing the fruit/veggies down in it, I assume I won't be able to find a replacement part, surely I can do without that? Thank you so very much for any help you can give me.
