Small Engines (Lawn Mowers, etc.): Chain Saw manual

Question
I bought a McCulloch Chain Saw years ago.  It is a MAC3227.  It still runs ok, but I long ago lost track of the user manual.  I would also like to have an illustrated parts list.  It would be nice to know what angle to grind the chain teeth and with what size file.  Can you give me a source?  I have tried to find one on the internet without success.

Answer
The file is 5/32 inch file and the angle should be 30 degrees.  

Not the manual for the model number you provided but page 16 covers sharpening:

Check the model number...the 3227 says it is a string trimmer, aka, weed eater.
