Fuel tank
IMPORTANT INFORMATION
Experience indicates that alcohol
blended fuels (called gasohol or using
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. Drain the gas tank, start the
engine and let it the run until the fuel
lines and carburetor are empty. Use fresh
fuel the next season. See Storage
Instructions for additional information.
Never use engine or carburetor cleaners
in the fuel tank or permanent damage
may occur.
WARNING!
Gasoline is highly flammable.
Observe caution and fill the
tank outdoors
(see the safety rules).
WARNING!
Fill to bottom of filler neck. Do
not overfill. Wipe off any
spilled oil or fuel. Do not store,
spill or use gasoline near an
open flame.
