Product Manuals - with search
Takes you directly to Product Manuals on the main Search & Downloads page.  Tip:  The best way to find Siemens manuals is to go to this link and then simply type a unique portion of the product for which you need a manual into the Search Field (e.g. "318") and the engine will find only Product Manuals with the term 318 in them.  This is far superior to going through the product 'trees' to find S7-300 and then trying to find manuals within that hierarchy. 

Siemens Manuals - Direct Access, Multiple Languages
Whereas the preceding link provides access to Siemens manuals (primarily) via searching, this link takes you to a page where you can find the manual you need via a series of selections.  Advantages of this link are that it is very easy to find manuals in a specific language and also that the manuals are apparently filtered to show only the most recent version of each manual.

Siemens Support Contacts - USA
