contain a total ofapproximately 40 oz. ofoil.

Gasoline WARNING: Experience indicates thatalcohol

blended fuels (calledgasohol or using ethanol or methanol) can attract moisture whichleads to separation and formationof acids during storage.-

Acidicgas can damage the fuel system of an engine

whilein storage. Toavoid engine problems, the fuel system should be emptied before storage for 30 days orlonger. Drain the gas tank, start the engine

and let it run untilthe fuellines and carburetor are empty. Use fresh fuelnext season. See STORAGE

instructionsfor additionalinformation. Never use engine orcarburetor cleaner products in the fuel tank

or permanent damage may occur.

Fill gasoline tank asfollows.

• Remove fuel cap.

• Make sure the container (fromwhich you will

pour the gasoline) is clean and free from rustor foreign particles. Never use gasoline that may

be stale from long periods of storage inthe container.
