I found it at Bob's Manuals. No registration needed! Craftsman 358791580 Manual
The manual is available from ManageMyLife.com which is one of Sears sites. A link to the manual is below and directions begin on page 8 and contine on the following page.
40:1 is the correct mixture for the fuel and 2 cycle oil. 3 oz. of 2 cycle oil per gallon of gas. I have Craftsman Line Trimmer 358.795190 (Model #). It has the quick release shaft for other attachments. Hopefully this will help you.
Go to Sears.com, then at the top of the page, click on Parts Direct. A box will appear where you can enter the Model #. On the page that comes up, click "View Manual". A .pdf file will open which you can save to your computer.

The Sears/Craftsman manual reqiures a 16:1 fuel mix. That is 8 oz. of 2-cycle oil to 1 gal. of gas. This is assuming you don't buy the generic "oil for all mixtures" stuff.
