I bought a hds580 karcher pressure washer serial #17893 I'm looking for a service manual

Not sure what the 'o.eltro' means? There is help in the link and the service manual for a different series of HDS washers. You could also contact Karcher direct.

Perhaps you contact the firm where you bought this? they should be able to help you in the first place.
Or perhaps even Karcher can help on their website? Worldwide Customer Service

do you want a "how to use the machine" or "parts diagrams" or "how to repair" ?

"how to use" is the same for all pressure washers...........

i guess you own a KB 302 1.994-923.0 but karcher dont list this "operators manual"

this is for the k 370 :

If you have a Karcher then you should always post your machines barcode.
The karcher barcode is on a silver sticker and is usually 15 digits long. Example 156987400000123 is actually model 1.569-874.0 and serial number 00123....
