The pictures are of poor quality and the text is in German, so it's probably not worth moving to the resources section, but I'll let the mods be the judge of that. Also I've left out several pages - those with only German text, and the diagrams of how to take the Sanden SD510 compressor apart - I guess most people wouldn't bother as it supposedly isn't compatible with the ozone-friendly R134a gas.
