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.
Important: Never use methanol, gasoline
containing methanol, gasohol containing more
than 10% ethanol, premium gasoline, or white
gas because the fuel system could be damaged.
Do Not add oil to gasoline.
Do Not use gasoline that has been stored since the
last mowing season or longer.
Do Not overll fuel tank. Never ll the fuel tank so
that the fuel level rises above a level that is 1/2 inch
below the bottom of the ller neck to allow for fuel
expansion and prevent fuel spillage.
Make sure you understand the controls, their
locations, their functions, and their safety
requirements.
Refer to the Maintenance section and perform all the
necessary inspection and maintenance steps.
