The fuel shut off valve shuts off the flow of fuel when the machine will not be used for a few days, when parking inside a building, and during transport to and from the job. Rotate the valve 1/4 turn clockwise to shut off fuel. Rotate the valve 1/4 turn counterclockwise to turn on fuel.
Pre-Start
Fill fuel tank. For best results use only clean, fresh regular grade unleaded gasoline with an octane rating of 87 or higher. To ensure freshness, purchase only the quantity of gasoline that you expect to use in
30 days. Using unleaded gasoline results in fewer combustion deposits and longer engine life. See Engine Owner’s Manual.
Do Not add oil to gasoline.
Do Not use methanol, gasoline containing methanol, gasohol containing more the 10% ethanol, premium gasoline or white gas. Using these fuels can damage the engine’s fuel system.
Do Not use gasoline that has been stored since the last mowing season or longer.
Do Not overfill fuel tank. Never fill the fuel tank so that the fuel level rises above a level that is 1/2 inch below the bottom of the filler neck to allow for fuel expansion and prevent fuel spillage.
