GASOLINE ENGINE
Adding a Fuel Stabilizer to Extend Fuel Storage Life
When adding a fuel stabilizer, fill the fuel tank with fresh gasoline. If only partially filled, air in the tank will promote fuel
deterioration during storage. If you keep a container of gasoline for refueling, be sure that it contains only fresh gasoline.
1. Add fuel stabilizer following the manufacturer’s instructions.
2. After adding a fuel 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 to the OFF position.
Draining the Fuel Tank and Carburetor
1. Place an approved gasoline container below the carburetor and use a funnel to avoid spilling fuel.
2. Remove carburetor drain bolt and sediment cup.
3. Move the fuel valve lever to the ON position.
4. After all fuel has drained into container, reinstall drain bolt and sediment cup. Tighten them securely.
Storage Precautions
1. Change engine oil.
2. Remove spark plugs.
3. Pour a tablespoon (5-10 cc) of clean engine oil into cylinder.
4. Pull starter rope several times to distribute oil in cylinder.
5. Reinstall spark plugs.
6. Pull starter rope slowly until resistance is felt. This will close the valves so moisture cannot enter the engine cylinder. Return
starter rope gently.
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.
Unless all fuel has been drained from the fuel tank, leave the fuel valve lever in the OFF position to reduce the possibility of fuel
leakage.
Position equipment so the engine is level. Tilting can cause fuel or oil leakage.
