Both are ok, but the manuals on paper are the best. You'll need to have the correct size reader for the fiche and it'll take a little getting used to the indexing system. When you slide the fiche in the machine, move the slide all the way to the upper left corner and you'll find the index for the service procedures. Once you figure it out, it's pretty nice.
