Hello bbforks,

We have here the EU requirements, and every truck must be registered by the Governmental Technical Inspection Office (polish abbreviation for it is UDT).
This is the same as TUV in Germany. I am sure you have the similar body in US.

Each newly registered truck must have the proper documentation (EU Declaration Of Conformity, Operating manual, all diagrams, etc) which has to given to this UDT office during the registration process.

When the new product is implemented on the market (like Linde 396-02), the UDT Inspectors sometimes are in need of the basic documentation, before the product is distributed.
Of course, they can ask authorised dealer for it, but because Linde in Poland is sometimes a bit inert, they prefer to ask me, while I cooperate with UDT very closely (in official and legal way).

Unfortunately, in this case, I didn't acquire this documentation yet, that's why I started this topic.

Sorry karait- can't help with the diagrams but was wondering what the purpose of the certification & standardization is?
