Unfortunately, the only way I know of to get an owners manual for Craftsman is directly from Sears for a price.
Looking at the Sears site it appears a lot of the parts are obsolete.
The Sears part number for the manual is 770-5875D, but they tell you to call (800) 252-1698 for availabilty.

Thanks, I have a call in to Sears and they are "researching" the availability of the manual and will get back to me in a week or so. I am not too optimistic that they will have one. I was able to download a manual for a newer model and there is some similarity that will get me thru the basics for now. I knew as soon as I bought this the manual would be an issue as documentation for older sears items is limited. The chipper itself seems to work pretty good though.
