Note: For the best performance, install a new blade before

the cutting season begins. During the year, file down any

small nicks to maintain the cutting edge.

DANGER

A worn or damaged blade can break, and a piece

of the blade could be thrown into the operator's

or bystander's area, resulting in serious personal

injury or death.

• Inspect the blade periodically for wear or

damage.

• Replace a worn or damaged blade.

Removing the Blade

1. Grasp the end of the blade using a rag or a thickly

padded glove.

2. Remove the blade nuts, the accelerator, and the blade

(Figure 37).

Sharpening the Blade

Service Interval: Every 50 hours

File the top side of the blade to maintain its original cutting

angle (Figure 38A) and inner cutting edge radius (Figure 38B).

The blade will remain balanced if you remove the same

amount of material from both cutting edges.

1. Sharpen at this angle only. 2. Maintain the original radius

Balancing the Blade

1. Check the balance of the blade by placing the center

hole of the blade over a nail or screwdriver shank

clamped horizontally in a vise (Figure 39).

Note: You can also check the balance using a

commercially manufactured blade balancer.

2. If either end of the blade rotates downward, file that

end (not the cutting edge or the end near the cutting

edge). The blade is properly balanced when neither

end drops.
