M. Use extreme care in handling gasoline and other fueis. 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. 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.
b. Replace gasoline cap securely and wipe off any spilled
gasoline before starting the engine as it may cause a fire
or explosion.
c. Extinguish all cigarettes, cigars, pipes and other sources
of ignition.
d. Never refuel unit indoors because flammable vapors will
accumulate in the area.
e. Never store the machine or fuel container inside where
there is an open flame or spark such as a gas hot water
heater, space 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. Check the blade and engine mounting screws at frequent inter
vals for proper tightness. Also visually inspect blades for wear
and/or damage (e.g., bent, cracked). Replace with biades
which meet original equipment specifications.
6. Keep all nuts, bolts, and screws tight to be sure the equipment
is in safe working condition.
7. Never tamper with safety devices. Check their proper opera
tion regularly.
