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.
