Important: Before tipping the mower to change
the oil or replace the blades, allow the fuel tank
to run dry through normal usage. If you must
tip the mower prior to running out of fuel, use a
hand fuel pump to remove the fuel. Always tip
the mower onto its side so that the air lter is
up in the air.
WARNING
Tipping the machine may cause the fuel to leak.
Gasoline is ammable, explosive, and can cause
personal injury.
