Before Starting

Oil Mix Ratio

Your Toro mower is powered by a 2-cycle engine
which requires a 32:1 mixture of gasoline and oil.
Failure to use the right mixture will result in serious
engine damage.
Toro Two-Cycle Oil is specially formulated to
provide superior lubrication, make starting easy and
prolong engine life. If Toro Two-Cycle Oil is not
available, mix two gallons of gasoline with 8 ounces
of another high grade two-cycle oil that the NMMA
or BIA-TCW certification printed on the label.
IMPORTANT: Never use automotive oil (i.e.
SAE 30, 10W30 etc.), two-cycle oil that is not
certified NMMA/BIA-TCW or the wrong mix
ratio because the engine can be damaged, and
it would not be covered by the Toro warranty.
POTENTIAL HAZARD
In certain conditions gasoline is extremely
flammable and highly explosive.
WHAT CAN HAPPEN
A fire or explosion from gasoline can burn
you, others, and cause property damage.
HOW TO AVOID THE HAZARD
Use a funnel and fill the fuel tank outdoors,
in an open area, when the engine is cold.
Wipe up any gasoline that spills.
Do not fill the fuel tank completely full.
Add gasoline to the fuel tank until the level
is 1/4" to 1/2" (6 mm to 13 mm) below the
bottom of the filler neck. This empty space
in the tank allows gasoline to expand.
Never smoke when handling gasoline, and
stay away from an open flame or where
gasoline fumes may be ignited by a spark.
Store gasoline in an approved container
and keep it out of the reach of children.
Never buy more than a 30-day supply of
gasoline.

Mixing Gasoline And Oil

This engine is certified to operate on unleaded
gasoline. The Toro Company strongly recommends
the use of fresh, clean, UNLEADED regular grade
gasoline with an octane rating of 85 or higher in Toro
gasoline powered products. Unleaded gasoline burns
cleaner, extends engine life, and promotes good
starting by reducing the build-up of combustion
chamber deposits. In countries other than U.S.A.,
leaded gasoline may be used if it is commercially
available and unleaded is unavailable.
For simplicity and best engine performance, mix 8
ounces of Toro Two–Cycle Oil with two gallons of
fresh, unleaded regular gasoline. Pour one gallon of
gasoline into an approved gasoline container and add
the correct amount of two–cycle oil. Install cap on
gasoline container and shake to mix oil and gasoline
thoroughly (Fig. 8). Slowly remove cap and add
remaining gasoline.
