Consult the Engine Owner's Manual for manufacturer's recommendations for
storage.
TO pREvENT FUEL-RELATED pROBLEMS
1.
Add Ethanol Shield
(sold separately) fuel stabilizer following the manufactur-
TM
er's 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.

NOTICE: Risk of property damage. Use only SIMPSON
Pump Guard or equivalent. Other products could be corrosive and/or contain alco-
hol which may cause pump damage.
1.
Turn off pressure washer and disconnect hoses from pump.
2.
Unscrew bottle valve from Pump Guard bottle and remove seal.
