I have the same jigsaw (+ a lot of other AEG power tools (aka Elektro Werkzeuge), including a hammer drill that's 3 years older than I am. So 44 years old) The AEG tools from this era are such high quality, man.. It's good that you refreshed it, but it was not even really necessary yet :) The grease was still ok (not perfect of course), and very little dirt. Which is amazing, since this machine is from around the late 1970s ~ early 1980s Anyways - quality maintenance job, sir :) Cheers from Amsterdam
