Hire David Sawyer McFarland
My advice! Hire David Sawyer McFarland (from The Missing Manuals) and let him rewrite all the manuals in a engaging, clear and funny way. Like all the excellent books he has written! Saves you 80% of the hours you spend now on answering the questions, because of the dry catalogs you call manuals. I have never encountered such a bunch of unclear, uncreative and uninspiring written manuals as the WA ones.
