How do you replace a weed eater trimmer line?

I can tell you how I do mine. Take about six feet of line. Put one end through the little hole in the spool. Just enough though to hold it. Now, find the arrow on the spool. wrap the line in the same direction as this arrow. You want to wrap it snug, not too tight. Now, put the free end throug the hole on the other part of the spool holder. Put the spool in the holder, making sure not to get the eline tangled with anything. Once it is in then put the bottom piece back on. That is it. It takes practice. It took some cursing at it and condeming it to hell a few times until I got it. Take your time. Good luck. Brad.
