How to replace trimmer line
To replace the trimmer line on your weed eater, start with an 10 foot piece of trim line. Remove the spool line from the trimmer, and start wrapping the trim line around the spool, leaving about 5 out. Push the end of the line through the exit hole, and then out the side of the trimmer. Replace the spool. You can find more information here: http://www.ehow.com/how_2308535_change-l…
