1. Use extreme care in handling gasoline and other fuels. They

are extremely flammable and the vapors are explosive. a. Store fuel and oil in approved containers, away from heat

and open flame, and out of the reach of children.

b. Check and add fuel before starting the engine. Never

remove gas cap or add fuel while the engine is running. Allow engine to cool at least two minutes before refueling.

c. Replace gasoline cap securely and wipe off any spilled

gasoline before starting the engine as it may cause a fire or explosion.

d. Extinguish all cigarettes, cigars, pipes and other sources of

ignition.

e. Never refuel unit indoors because flammable vapors will

accumulate in the area.

f. 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.

2. Never run your machine in an enclosed area as the exhaust from the engine contains carbon monoxide, which is an odor less, tasteless and deadly poisonous gas.

3. 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.

4. Before cleaning, repairing, or inspecting, make certain the impeller and all moving parts have stopped. Disconnect the spark plug wire and keep wire away from spark plug to prevent accidental starting. Do not use flammable solutions to clean air filter.

5. Keep all nuts, bolts, and screws tight to be sure the equipment is in safe working condition.

6. Never tamper with safety devices. Check their proper opera

tion regularly.

7. Do not alter or tamper with the engine’s governor setting. The

governor controls the maximum safe operating speed of the engine. Over-speeding the engine is dangerous and will cause damage to the engine and to other moving parts of the

machine.
