• Add unleaded regular gasoline, slowly to fuel tank. Be

• Install fuel cap and wipe up any spilled gasoline.
IMPORTANT: It is important to prevent gum deposits
from forming in essential fuel system parts such as the
carburetor, fuel filter, fuel hose or tank during storage.
Also, experience indicates that alcohol-blended fuels (called
gasohol, ethanol or methanol) can attract moisture which
leads to separation and formation of acids during storage.
Acidic gas can damage the fuel system of an engine while in
storage.
To avoid engine problems, the fuel system should be
emptied before storage of 30 days or longer. See "Storage"
on page 11. Never use engine or carburetor cleaner
products in the fuel tank or permanent damage may occur.
