Maintaining the Cutting Blade
Always mow with a sharp blade. A sharp blade cuts
cleanly and without tearing or shredding the grass blades.
1. Stop the engine and wait for all moving parts to stop.
2. Disconnect the wire from the spark plug (Fig. 10).
3. Drain the gasoline from the fuel tank; refer to
Emptying the Fuel Tank and Cleaning the Fuel Filter
on page 18.
4. Tip the lawn mower onto its right side (Fig. 20).

Inspecting the Blade
Carefully examine the blade for sharpness and wear,
especially where the flat and the curved parts meet
(Fig. 21A). 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. 21B and 21C), 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 lock washer, the
accelerator, and the blade (Fig. 20).
