Bicycle "owner's manuals" have always been rather minimal. Those from Asian manufacturers have often been full of misinformation, oversimplification and amusing mis-translations.
This manual is pretty typical, used for all Centurion and Diamondback models from the bottom to the top of the line.
The identical pages probably were used by quite a few other manufacturers. It is offered mainly for amusement and because owners of classic bikes often go to a lot of trouble trying to obtain the owner's manual for their bike, only to be sadly disappointed when they discover what a pitiful document it is.
I have added links to some of my articles on the relevant pages, where you can find more useful information.

Note that the Centurion name lives on in an unrelated bike brand from Denmark.
