SClean the unit before storing. Pay particu- lar attention to the air intake area, keeping
it free of debris. Use a mild detergent and sponge to clean the plastic surfaces.
SDo not store the unit or fuel in a closed area where fuel vapors can reach sparks or an open flame from hot water heaters, electric
motors or switches, furnaces, etc.
SStore in a dry area out of the reach of chil- dren.
CAUTION: It is important to prevent gum deposits from forming in essential fuel system parts such as the carburetor, fuel fil- ter, fuel hose, or fuel tank during storage. Al- cohol blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to fuel mixture separation and formation of acids during storage. Acidic gas can damage the engine.
