If you are using Black and Decker trimmer to trim the grass, sometimes you might notice that the trimmer line would keep coming out and too much line in the end.
Normally, you could control how much the trimmer line out through the button on the trimmer.
However, sometimes it just does not work and you have to disable the auto trimmer line feed and change it to the manual way.
As shown in the video above, you have 2 ways to do this, first is to apply tape on the feeding component.
Another way is to simply wind the trimmer string in another direction to make it manual feed.
