You're Doing it Wrong! Respool your Stihl Trimmer Line in Seconds.
I can't believe this. For years I've been restringing my Stihl weed wacker string trimmer by removing the trimmer head. I had no idea that you could restring the spool in seconds without removing it.
It's listed in the Stihl owners manual, but this will save you time and frustration. Check it out!!!
