How can I change the spool on my YardWorks grass trimmer/edger?

Question

I need to change the spool on my grass trimmer. I cannot find the manual and need help!

Thank you

Answer 1

There maybe a k**b at the bottom center of the trimmer, turn that counter clockwise.  

Answer 2

You can probably find the manual on line. Usually, to remove the spool, you push in and turn the big round piece on the bottom (the one you hit on the ground to advance the string). You then unscrew it and remove the old spool and replace it.
