Makita Powerhead XUX01 assembly and the EM405MP weed whacker

I hope this video helps people out. The included instructions aren't very well written and the tools they give you don't really help as much as they should.
This is the Makita Powerhead XUX01 and the EM405MP weed whacker attachment. I picked it because I am already vested in Makita power tools and I have several batteries. With the two 3.0AH batteries I managed about 15 min of run time on the top speed setting and only marginally better on the medium setting. Not really spectacular but in my opinion these are kind of small batteries for this draining of a task. The lowest speed setting works ok for edging and light work but wasn't very good at much else. It took extra passes to do the same work the high and medium settings do.
The power of this tool is pretty amazing it blasted through tall thick grass and thick tough stalked weeds with ease.
I have two 5AH batteries arriving tomorrow that should help with the run time.
