CONTROLS
WARNING! Gasoline is very flammable.
Observe caution and fill the tank outdoors (see
the safety section).
IMPORTANT INFORMATION Experience
shows 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 must be emptied before storage of 30
days or longer. Drain the gas tank, start the
engine and let it run until the fuel lines and
carburetor are empty. Use fresh fuel the next
season. See Storage for more information. Do
not use engine or carburetor cleaners in the
fuel tank or permanent damage can occur.
WARNING! Fill to the bottom of the filler
neck. Do not add too much gasoline. Wipe
off spilled oil or fuel. Do not keep, spill or use
gasoline near an open flame.
WARNING! The engine and the exhaust
system become very hot during operation.
There is a risk for burns if touched. Let engine
