Echo trimmer had narrow shield. Bought wider one which reduced rocks and debris

  • Robert from COEUR D ALENE, ID

Easiest repair ever. Turn the trimmer upside down so you can access the string assembly. Find the small hole in the shaft beneath the string assembly and insert a heavy gauge nail into it to hold the shat in place. Turn the string assembly counterclockwise until it comes off. Lift off the round metal piece that was under the string assemb ly.Find the 3 screws holding the shield in place and unscrew them. Pull the shield off. Install the new one in reverse order. I used the original hex screws as the new ones were philips head. Hex worked perfectly. I was amazed how easy thus was to do.
