Lots of Google and Amazon searching failed to turn up a current or old book on using the Ankarskrum. I didn't try non-USA Amazon websites, but I'd be surprised if there's never been one in any language.
I am not aware of any book focused on just that mixer, though the few cookbooks I have seen on a particular small appliance were pretty disappointing . As law and loaf says, there are plenty of videos on youtube and if you have a question, ask here, someone should be able to help.
I would do a you-tube search, there are tons of videos on using the Ankarsrum. I don't know of any books though, unless you're looking for the owners manual which can be found here: https://www.ankarsrumoriginalusa.com/public/images/brochures/Ankarsrum%20USA_English%20Manual.pdf

It occurs to me that if customers need a third party book to figure out how to use it, maybe it is not the right mixer to own.
Rose's "The Bread Bible" includes some tips on using the machine, but refers to it as "Magic Mill".
