1.Stop the engine and wait for all moving parts to stop.

2.Disconnect the wire from the spark plug (Fig. 6).

3.Drain the gasoline from the fuel tank.

4.Tip the lawn mower onto its right side (air cleaner up) (Fig. 17).

Inspecting the Blade

Carefully examine the blade for sharpness and wear, especially where the flat and the curved parts meet (Fig. 18A). Because sand and abrasive material can wear away the metal that connects the flat and curved parts of the blade, check the blade before using the lawn mower. If you notice a slot or wear (Figs. 18B and 18C), replace the blade; refer to Removing the Blade on page 17.

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 bolt, the lockwasher, the accelerator, and the blade (Fig. 17).
