i have at the moment, 2 echo trimmers with the exact same symtoms. they run excellent, but the head won't move. i took one apart, to see if it was the shaft, or clutch, and the shaft if i spin in manually with my fingers, the head spins. soo, now that i took the cover off, and the shoes are right in my face, how do you get these things off. i disconnected a spring, thinking maybe they where retaining the shoes, but no. any ideas here, i would like to get to the repair shop beofre they close at 4-5 o'clock. i came home early, and left the last account i did half trimmed!
