Hello everyone, I am a first post newbie in the middle of a project and need some reference manuals. Currently repairing my grandfather's 600 series McCulloch chainsaw (broken crankshaft and chain brake) and I need to make sure it all gets put back together properly. I already have two different IPLs (Versions 215036-R3-E & 218689-01-E) but would also like to find some owner's manuals and workshop manuals. I have found several cover page images online of the PRO MAC 610/650 (Versions 93488/R2 & 93488-R8) and also the PRO MAC 655 (Version 216158) OMs but I can't seem to find any pdf versions of the complete manual that I trust to download. The McCulloch customer service hotline could find no information regarding this older series of saws nor are the manuals available for download on their website. Any help from the forum would be greatly appreciated. Thank you.
