Default Hatz E780

Hi I just bought two Hatz engines coupled to diaphragm pumps manufactured by a Dutch company called ZW Pompen, my question is does anyone have an internet location where I can download any info or manuals on the E780 & ES780 (I have one of each but externally they look the same.....
Also if anyone has any info at all on these 4" pumps I would be very greatful.

You might consider the link:

On these engines the main thing is to twist open the decompression valve (DCV) , and then crank with much effort in the beginning to maximize rotational speed before the DCV ratches too far close. If your are slow doing this you will run out of bicep muscle.
