Dear Jewels,

Thank you for your feedback. We are sorry to hear of the challenge you are experiencing with your string trimmer. This unit is only compatible with one trimmer head, and we do not have another trimmer head that can physically go on this trimmer. The trimmer head on this unit is made for easy replacement of the string on the spool. We understand that for some new customers this task may seem overwhelming/difficult but once they do it a few times it’s quite easy – as easy as replacing a spool. It is also cheaper and more convenient for customers to rewind the trimmer head because they can use any generic .080” trimmer line(purchased at your local hardware store) and save money on more costly replacement spools. There are two methods in which the trimmer line can be replaced. You will need approximately 15' of trimmer line at .080" inches in diameter. For the first method: Note the hash mark on the knob and the hash mark on the spool cover, while holding the spool cover in place with one hand , turn the knob until the hash mark line up with the hash mark on the spool cover. Then take the trimmer line and feed it through one of the holes in the side of the head until there is an even amount on both sides. Then wind the line into the spool by turning the knob clockwise. If you wish to readjust the line or if the line has been wound too short, push down on the knob and wind it counterclockwise. Be sure to leave about 5 inches of slack on each side of the spool. Second method: Remove the spool cover by simultaneously pushing the two tabs located on side of the spool cover. The cover should spring off, lift the spool out and feed line through hole in the center of the spool until you get an even amount of line on each side. Put the spool back in the trimmer head, making sure that both sides of the line go back into the grooves in the trimmer head, continue to hold the spool in place. Take the spool cover and put it back onto the trimmer, using both hands press down firmly to ensure that the taps lock into place, you can now rotate the knob on the spool clockwise to rewind the line back in making sure to leave the 5 inches of line on each side of the spool.
