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. 11).
3. Drain the gasoline from the fuel tank; refer to
Emptying the Fuel Tank and Cleaning the Fuel Filter
on page 22.
4. Tip the lawn mower onto its right side (Fig. 26).

Inspecting the Blade
Carefully examine the blade for sharpness and wear,
especially where the flat and the curved parts meet
(Fig. 27A). 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. 27B and 27C), replace the
blade; refer to Removing the Blade on page 21.
