Hi Joan, thank you for using Answer Army!
Sometimes the cables in the shafts don't line up with each other very smoothly. In other words, one will not fit into the other. Try turning the trimmer head a little, and reinstalling the shafts together. Be sure to align the grooves on the upper and lower shafts before installing.
Please let us know if you get it to align and again thank you for using Answer Army.
