How do you replace the line on a weedeater trimmer?

I'm not sure of your model but most weedeaters are basically the same. At the point where the weedeater meats the ground below where the nylon lines protrude out the side of the unit, there is a knob. It usually has a bit of a spring action to it. In other words, when you push on it, it depresses and allows the nylon string to escape. That same knob will also screw off. Sometimes it's kind of hard to get it to turn because the whole base wants to turn with it. Once you get it to turn the whole knob will come off and you can remove the inner chamber where the string is stored. There are usually little directions etched in the plastic but it is pretty self explanitory from there. Hope I helped.
