Maintaining the Blade

A straight, sharp blade provides the best cutting
performance. Regularly inspect and sharpen the blade.
Warning
The blade is sharp; contacting the blade can result
in serious personal injury.
Wear gloves or wrap the sharp edges of the blade
with a rag.
1. Stop the engine and wait for all moving parts to stop.

Warning
Tipping the lawn mower may cause the fuel to leak
from the carburetor or the fuel tank. Gasoline is
extremely flammable, highly explosive and under
certain conditions can cause personal injury or
property damage.
Avoid fuel spills by running the engine dry or
removing gasoline with a hand pump; never
siphon.
