How can I change the trimmer line on my trimmer?

To change the trimmer line on your trimmer, first, turn off the trimmer and disconnect it from the power source. Remove the spool housing by pressing the tabs on the sides. Take out the old trimmer line spool and replace it with a new one, following the arrows for the direction of the line. Cut the line to the desired length and feed it through the holes in the spool. Finally, reassemble the spool housing and you're ready to trim.
