Important: Before tipping the machine to change
the oil or replace the blade, allow the fuel tank to
run dry through normal usage. If you must tip
the machine prior to running out of fuel, use a
hand fuel pump to remove the fuel. Always tip the
machine onto its side, with the dipstick down.
WARNING
Tipping the machine may cause the fuel to leak.
Gasoline is flammable, explosive, and can cause
personal injury.
Run the engine dry or remove the gasoline with a
hand pump; never siphon.
