Draining the Gasoline
POTENTIAL HAZARD
• If gasoline is spilled on a hot engine, it
could ignite.
WHAT CAN HAPPEN
• Contact with burning gasoline could cause
serious personal injury.
HOW TO AVOID THE HAZARD
• Drain gasoline from a cold engine only.
1. Shut off the engine and allow it to cool.
IMPORTANT: Drain gasoline from a cold
engine only.
2. Make sure the spark plug wire is off of the spark
plug. Remove the cap from the fuel tank and use
a pump-type syphon to drain the fuel into a clean
gas can.
Note: This is the only procedure
recommended for draining fuel.
Storage
For long-term storage, either drain the gasoline from
the fuel tank or use a fuel additive before storing. To
drain the gasoline, refer to Draining the Gasoline
above.
If You Drain the Gasoline
1. After the fuel is drained, start the engine and let
it idle until all the fuel is consumed and the
engine stops.
2. Repeat the starting procedure two more times to
ensure that all the gas is removed from the
engine. If the gasoline is not drained, gum-like
varnish deposits will form and cause poor engine
operation, even starting problems.
If You Leave the Gasoline in the Tank
Fuel can be left in the gas tank only if a fuel additive
such as Toro’s Stabilizer/Conditioner is added to the
gasoline and run through the engine before storing.
Toro’s Stabilizer/Conditioner is a petroleum distillate
based stabilizer/conditioner. Toro does not
recommend stabilizers with an alcohol base such as
ethanol, methanol or isopropyl. Use the fuel additive
in the recommended quantities as specified on the
container. Under normal conditions, fuel additives
remain effective in the fuel for six to eight months.
Coating the Inside of the Cylinder
1. Remove the spark plug and pour two
tablespoons of engine oil into the spark plug
hole in the cylinder.
2. Pull the starter rope slowly to coat the inside of
the cylinder.
3. Reinstall the spark plug and tighten to 10 ft-lbs
(13.6 Nm). DO NOT REINSTALL THE
SPARK PLUG WIRE ONTO THE SPARK
PLUG.
4. Slowly pull the starter rope until resistance is felt
due to compression pressure, then stop. Release
the starter rope tension slowly to prevent the
engine from reversing due to compression
pressure. This position closes both the intake and
exhaust ports to prevent cylinder bore corrosion.
Adjusting the Carburetor
The carburetor has been set at the factory and
normally won’t require any further adjustment.
However, when operating the engine at altitudes 5000
feet above sea level and higher, the carburetor jets
may have to be changed. Contact your Authorized
Toro Service Dealer for assistance.
