Definitely some errors in there - e.g. "O ring list" fits on one page - I got
way more than that with mine
I've still got my 'original' classic kiss manual sowmehere (it's a bit soggy & crumpled tho) - it only covers disassembly of the unit, with no clues about which O rings are factory fitted and which aren't - made the first assembly and test a bit of a challenge!
