In this section I am listing the NC related documentation that I either own or have access to.
I am always interested in acquiring or borrowing additional material. Particularly sales brochures and technical information like service bulletins, electrical prints a.s.o. are wanted.
Please contact me at Kattenes@web.de if you can contribute in any way. I always prefer to trade information and can distinguish between public and non-public information 
, but I also buy material outright (at down-to-earth enthusiast prices, I care about content, not collectability). If you provide information, you will have to tell me if I can publish it here, or not, and if I should mention your name in the reference.
As a rule I consider anything publishable that was available to the customer at some point in time. This includes manuals, brochures and other machine documentation.
Addendum:
This web-site is not commercial and the documents listed below are not for sale, but I will gladly trade against other documentation not already listed here. The purpose is to grow the knowledge base. This can not occur if everyone only wants something, but never contributes anything. If you have no Deckel documentation to trade, you can also offer other documentation, which I may then put in the download area. You may also offer other stuff of interest. So far I mostly receive requests like "hey dude, mail me immediately the documents A,B,C and F". People who lack basic communication skills and courtesy will not be served. It is expected that you relay who you are, what machine you have, what your problem is, and what you may be able to contribute. Machine pictures are appreciated! This being said, please consider this the reason in case you do not hear back, Dude.
