When you said "full repair manual" I was expecting something much more interesting, e.g. with schematics and boardviews which I bet many un-authorized repair shops already have, but after taking a look, I'd say it's only better than nothing. It looks more like a very detailed parts-swapping guide, probably the internal training material they already had, with additional lawyer-motivated warnings/disclaimers added.

...and installing the battery requires a special tool? It reminds me of German engineering, or some parody thereof.
