HAMM brand compaction manuals

Hello everyone.

I introduce myself, my name is José Luis, and I am a mechanic specialized in public works machinery, and I am looking for the compactor workshop network, of the Hamm brand, although in reality they have good for any brand, Hamman, Lebrero, etc.

If anyone knows where they can get or get off the network, I appreciate it since I have searched a lot but I find almost nothing of machinery, civil works.

Thank you all.
