III. SERVICE
i
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 gaso
line before starting the engine as it may cause a fire or explo
sion.
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 operation
regularly.
7. After striking a foreign object, immediately stop the engine, dis
connect the spark plug wire from the spark plug, and
thoroughly inspect the unit for any damage. Repair damage
before starting and operating unit.
8. 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.
9. Check the vacuum bag frequently for wear. Replace if worn or
damaged.
10. Keep vacuum bag free of debris when not in use.
