OR USING ETHANOL OR METHANOL) CAN ATTRACT MOISTURE WHICH LEADS TO SEPARA- TION AND FORMATION OF ACIDS DURING STOR- AGE. ACIDIC GAS CAN DAMAGE THE FUEL SYS- TEM OF AN ENGINE WHILE IN STORAGE.

•Drain the fuel tank.

•Start the engine and let it run until the fuel lines and carburetor are empty.

•Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur.
