My understanding is thats Echos design.
Stihl uses it now, under license.
Guy at work bought a Stihl last year. Couple weeks ago he was grumbling
about how hard it was to restring.
I ask him if it was this head. He had no idea.
Explained how it worked. That night I got a msg.
He was tickled at how easy it worked.
Since he wasn't tearing it apart to feed it anymore.
Amazes me how so many people think they know everything.
And refuse to read manuals.
I read every manual on everything I get.
And usually pick up something doing it.
