    Asked by Mick May 29, 2017

    Turn the knurled cap while holding the bottom and look thru the holes where the line exits and turn until you can see all the way thru . Then insert line around 10 ft. and pull them even on both sides then hold bottom and twist the knurled cap until desired lenth is reached...:-)

    I would suggest doing a mod for this head. The mod can be found online and what it does is allows you to add a 3/8” bolt and washer to it to allow the plastic to last longer when bumping along sidewalks and concrete. The bolt acts as a metallic bump. The installation will fit mostly any model wmtrumner. I have a Milwaukee m18 and it mounted well. It holds a lot of line. I run .95 and it holds 30” and that’s a lot of line. The line goes in so easily it’s no hassle. The universal moi ting kid makes it easy. But if you get this perform the mod to add a bolt and washer to this head. You’ll get a lot more usage out od it before the plastic wear thin.

    Had to convert it for use with my Stihl, this involves taking the threaded insert out of the old head and putting it in the new one. Works well!
