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.
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.
1. Disconnect the spark plug wire from the
spark plug.
2. Remove the blade locknut that holds
the blade to the drive shaft.
WARNING: To remove or tigh-
ten the blade locknut, always
use the method shown in
Figure 13. Always position the holding
wrench on the nut behind the blade.
3. Remove the blade.
4. Install a new blade and blade locknut.
Tighten the blade locknut to a torque of
40–45 foot pounds.
