How To Replace The Blade

The blade is subject to wear and damage, such as

nicks and dents. This is normal and does not affect its

function.

The blade does not require sharpening. Do not

sharpen the blade.

If both sides of the blade (A) are severely worn or

damaged, replace as follows.

1 Disconnect the spark plug wire from the spark

plug.

2 Remove the blade locknut (B) that holds the blade

to the drive shaft.

NOTE: To remove or tighten the blade locknut,

always use the method shown in Figure 25.

First, secure wrench (C) onto the nut located

behind the blade. Then, to remove or tighten

the blade locknut, turn the wrench (D).

3 Remove the blade.

4 Install a new blade and secure with the blade

locknut. Tighten the blade locknut to a torque of

40−45 foot pounds.

5 Connect the spark plug wire to the spark plug.

Figure 25: Blade Removal

• Never sharpen the blade, always replace.

Sharpening the blade will cause the blade to

shatter.

• Keep a safe distance from rotating blade

during operation.

Sharpening can damage the blade

and cause it to break.

Thrown debris can cause severe

laceration.
