How do you change the trimmer line?

Hi,
Sears has had many people make their trimmers, so without model numbers only a general explanation is possible. Just answered is the Bolens question, and you could look at it (some were made by the same company) or get the numbers off the machine and go to:
Home Improvement Projects, Product Manuals & Home Management Tools - Managemyhome.com
And get your manual.
