2 . After adding a gasoline stabilizer, run the engine
outdoors for 10 minutes to be sure that treated gasoline
has replaced the untreated gasoline in the carburetor .
3 . Stop the engine, and move the fuel valve lever to the
OFF position .
Draining the Fuel Tank and Carburetor
GASOLINE IS HIGHLY FLAMMABLE AND EXPLOSIVE, AND
YOU CAN BE BURNED OR SERIOUSLY INJURED WHEN
HANDLING FUEL.
• STOP ENGINE AND KEEP HEAT, SPARKS, AND FLAME
AWAY.
• HANDLE FUEL ONLY OUTDOORS.
• WIPE UP SPILLS IMMEDIATELY.
1 . Place an approved gasoline container below the
carburetor, and use a funnel to avoid spilling fuel .
2 . Drain the fuel tank and carburetor .
Remove the carburetor drain bolt, then move the fuel
valve to the ON position .
3 . After all the fuel has drained into the container, reinstall
the drain bolt (carburetor equipped with a drain bolt type
only) . Tighten the drain bolt or drain screw securely .
Engine Oil
Change the engine oil (see
) .
Engine Cylinder
1 . Remove the spark plug (see
) .
2 . Pour a tablespoon 5…10 cm
3
(5…10 cc) of clean engine
oil into the cylinder .
3 . Pull the starter grip several times to distribute the oil in
the cylinder .
4 . Reinstall the spark plug .
5 . Pull the starter grip slowly until resistance is felt and the
rib on the flywheel aligns with the notch on the fan cover .
This will close the valves so moisture cannot enter the
engine cylinder . Return the starter grip gently .
Storage Precautions
If your engine will be stored with gasoline in the fuel tank
and carburetor, it is important to reduce the hazard of
gasoline vapor ignition . Select a well-ventilated storage area
away from any appliance that operates with a flame, such as
a furnace, water heater, or clothes dryer . Also avoid any area
with a spark-producing electric motor, or where power tools
are operated .
If possible, avoid storage areas with high humidity, because
that promotes rust and corrosion .
Keep the engine level in storage . Tilting can cause fuel or
oil leakage .
With the engine and exhaust system cool, cover the engine
to keep out dust . A hot engine and exhaust system can
ignite or melt some materials . Do not use sheet plastic as a
dust cover .
A nonporous cover will trap moisture around the engine,
promoting rust and corrosion .
Removal from Storage
Check your engine as described in
If the fuel was drained during storage preparation, fill the
tank with fresh gasoline . If you keep a container of gasoline
for refueling, be sure it contains only fresh gasoline . Gasoline
oxidizes and deteriorates over time, causing hard starting .
If the cylinder was coated with oil during storage
preparation, the engine will smoke briefly at startup . This
is normal .
Transporting
If the engine has been running, allow it to cool for at least 15
minutes before loading the engine-powered equipment on
the transport vehicle . A hot engine and exhaust system can
burn you and can ignite some materials .
Keep the engine level when transporting to reduce the
possibility of fuel leakage . Turn the fuel valve to the OFF
