Anyone have any links/videos/information regarding cleaning/maintaining an M39 Dosatron? I really want to get inside and change out the gaskets, deep clean the groups, and tighten up or rebuild our wands. I'm inclined to just crack it open and figure it out on my own but some guidance would be nice because the parts are on the expensive end and if I break it and we call our La Cimbali specialists we end up paying $150/hr for the guy to take his time and talk to my baristas.
Thanks in advance.
