from the engine contains carbon monoxide, which is an odorless, tasteless, and a deadly
poisonous gas.
B. Store all fuel and oil in containers specifically designed and approved for this purpose
and keep away from heat and open flame, and out of the reach of children.
C. Replace rubber fuel lines and grommets when worn or damaged and after 5 years of
use.
D. Fill the gasoline tank outdoors with the engine off and allow the engine tocool
completely. Don't handle gasoline if you or anyone nearby is smoking, or if you're near
anything that could cause it to ignite or explode. Reinstall the fuel tank cap and fuel
container cap securely.
E. If you spill gasoline, do not attempt to start the engine. Move the machineawayfrom
the area of the spill and avoid creating any source of ignition until the gas vapors have
dissipated. Wipe up any spilled fuel to prevent a fire hazard and properly dispose of the
waste.
F. Allow the engine to cool completely before storing in any enclosure. Never store a
machine that has gas in the tank, or a fuel container, near an open flame or spark such
as a water heater, space heater, clothes dryer or furnace.
G. Never make adjustments or repairs with the engine running. Shut down the engine,
disconnect the spark plug wire, keeping it away from the spark plug to prevent
accidental starting, wait 5 minutes before making adjustments or repairs.

safe operation speed and protects the engine. Over-speeding the engine is dangerous
and will cause damage to the engine and to the other moving parts of the machine. If
required, see your authorized dealer for engine governor adjustments.
