How to Install a Blade on an Echo Weed Eater
- 1). Attach the metal blade shield to the end of the trimmer using the included hardware.
- 2). Flip the trimmer head upside-down and slide the upper plate onto the end of the shaft.
- 3). Place the blade on top of the upper plate, positioning it so the arrow painted on the blade points in the same direction as the blade rotates.
- 4). Place the lower plate over the center of the blade and attach it by turning a 10 mm left-handed locking nut counterclockwise until it's tight enough to hold the blade in place.
- 5). Line up the hole in the upper plate and the notch in the gear housing. Slide the locking tool into the hole.
- 6). Tighten the 10 mm nut until it is securely in place. Slide a cotter pin through the hole at the end of the shaft. Bend the ends of the cotter pin around the shaft.
- 7). Remove the locking tool.
