• Replace gasoline cap securely and wipe off any spilled
gasoline before starting the engine as it may cause a fire or
explosion.
• Extinguish all cigarettes, cigars, pipes and other sources of
ignition.
• Never refuel unit indoors because flammable vapors will
accumulate in the area.
• Never store the machine or fuel container inside where
there is an open flame or spark such as a gas hot water
heater, clothes dryer or furnace,
Never run your machine in an enclosed area as the exhaust from
the engine contains carbon monoxide, which Is a odorless,
tasteless and deadly poisonous gas.
To reduce fire hazard, keep engine and muffler free of leaves,
grass, and other debris build-up. Clean up fuel and oil spillage.
Allow unit to cool at least 5 minutes before storing.
Before cleaning, repairing, or inspecting, make certain the
