Hi Scott,
Intertec Publishing puts out a Chain Saw Service Manual about
every 5 or 6 years.The 10th edition(1998) is the latest with a
new edition due out soon.My 9th edition(1993) is over 550 pages and has 29 manufacturers listed - from Allis Chalmers to Tanaka.
The 6th edition(1980) has 20 manufacturers from Allis Chalmers to Stihl.It is a little over 300 pages.
If you have a library close they should have some of the editions.
You can purchase them on Amazon.com,Walmart.com or E-bay under $20.
Regards,
Ray
