HOW TO REPLACE THE BLADE
The blade is subject to wear and damage, such as nicks and dents. This will not gener- ally affect its function.
1.Disconnect the spark plug wire from the spark plug.
The blade is designed to not require sharp- ening. Do not attempt to sharpen the blade. The blade is also reversible. If nicks or dents are excessive, remove the blade and turn it around. This will provide a fresh cut- ting edge. Replace the blade if both sides are worn or damaged.
WARNING: Do not sharpen the blade. Sharpening can damage the blade and cause it to break,
which can cause injury to yourself or to others.
To replace the blade, follow the steps below.

WARNING: To remove or tigh- ten the blade locknut, always use the method shown in
