Note: Determine the left and right sides of the machine from the normal operating position.
WARNING
If you leave the wire on the spark plug, someone could accidentally start the engine. Accidental starting of the engine could seriously injure you or other bystanders.
Disconnect the wire from the spark plug before you do any maintenance. Set the wire aside so that it does not accidentally contact the spark plug.
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 by removing the gasoline with a hand pump; never siphon.
WARNING
The engine can become very hot. Touching a hot engine can cause severe burns.
Allow the engine to cool completely before service or making repairs around the engine area.
