STORAGE

Engine

Consult the engine instruction manual for the

manufacturer's recommendations forstorage.

To Prevent Fuel-Related Problems

1. Add Ethanol Shield™ fuel stabilizer following the

manufacturer’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.

Pump

The manufacturer recommends using SIMPSON® /

POWERWASHER™ Pump Guard or equivalent when storing

the unit for more than 30 days and/or when freezing

temperatures are expected. SIMPSON® / POWERWASHER™

Pump Guard is environmentallyfriendly.

NOTE: Using pump guard helps provide proper lubrication

to the internal seals of the pump regardless of temperature

orenvironment.
