Great copy of the manual, has all information required for servicing,
;
I work at an authorized service center and I can tell if a manual is as it should be. This one is. It may be a scan, but a very good one at that. The interesting part for me was the curcuit diagram which was scanned at high quality, making it as good as the original. I will definitely be back as a customer. I need not say this, but I will: the price was the best. Thank you owner-manuals.com .

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.
