TO PREVENT FUEL-RELATED PROBLEMS
1. Add Ethanol Shield fuel stabilizer following the manufacturer's
TM
instructions. When adding a gasoline 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.
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. Turn the fuel valve to the OFF position.
4. Continue to run the engine until it stops from the lack of fuel in the
carburetor fuel bowl. Running time should be less than 3 minutes.
