Thank you very much for this Service Manual, it helped us a lot to repair the M-4318!
...BUT: The parts list is missing and the free parts katalog on web isn't complete, so now we don't know the part numbers of the defect parts :(
We had to build them out of a working machine, and need the numbers to reorder the missing parts now.
Complete original Service Manual in good (scan) quality!
