Gasoline

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.
This engine is certified to operate on unleaded
gasoline. Toro 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.

IMPORTANT: Do not mix oil with the gasoline.
Do not use gasoline that has been stored in an
approved container from one season to the next.
Toro also recommends that Toro
Stabilizer/Conditioner be used regularly in all Toro
gasoline powered products during operation and
storage seasons. Toro Stabilizer/Conditioner cleans
the engine during operation and prevents gum-like
varnish deposits from forming in the engine during
periods of storage.
IMPORTANT: Some fuels, called oxygenated or
reformulated gasolines, are gasolines blended with
alcohols or ethers. Excessive amounts of these
blends can damage the fuel system or cause
performance problems. Never use methanol,
gasoline containing methanol, gasohol containing
more than 10% ethanol or white gas because
engine fuel system damage could result. If any
undesirable operating symptoms occur, use
gasoline with a lower percentage of alcohol or
ether.
Do not use fuel additives other than those
manufactured for fuel stabilization during storage
such as Toro's Stabilizer/conditioner or a similar
product. Toro's Stabilizer/conditioner is a
petroleum distillate based conditioner/stabilizer.
Toro does not recommend stabilizers with an
alcohol base such as ethanol, methanol or
isopropyl. Additives should not be used to try to
enhance the power or performance of machine.
1. Clean around fuel tank cap and remove cap from
tank (Fig. 9).
2. Using unleaded gasoline, fill fuel tank to within
1/4" to 1/2" (6 to 13 mm) from top of tank, not
into filler neck. Do not fill tank full.
3. Reinstall fuel tank cap and wipe up any spilled
gasoline.
4. Connect spark plug wire (if disconnected)
(Fig. 9).
