Specific Safety Information for Gasoline Engine
Driven Pumps
1.
Carefully read the instruction manuals supplied by the
engine manufacturer before attempting to assemble,
disassemble or operate the engine or any other part. The
"Warning" and "Caution" statements in this manual signal
potentially hazardous conditions to the operator or
equipment. Know when these conditions can exist. Take
necessary steps to protect personnel, as well as equipment.
Gasoline is a highly combustible fuel. Use it with care! The
improper use, handling and/or storage of gasoline can be
dangerous. Help prevent accidents by following these safety
rules:
a.
Use gasoline only as a fuel, never as a cleaning fluid.
b.
Always use an approved container to hold or store gasoline.
Never store gasoline in familiar containers such as milk
gallons or soda pop bottles.
c.
Never store gasoline near a heater or an open flame.
d.
When storing or using gasoline, make sure container is out
of the reach of children.
e.
Never add gasoline to a running or hot engine. Spilled
gasoline on a hot engine may cause a fire or an explosion.
Fill gasoline tank outdoors and wipe up any spills.
f.
Have a fire extinguisher nearby. Be sure extinguisher is in
operating condition
– check the pressure gauge or indicator.
Be familiar with its proper use. Consult the local fire
department for the correct type of extinguisher for your
application. Extinguishers rated ABC by the National Fire
Protection Association are appropriate for all applications.
g.
On permanent installations, be sure all fuel supplies have a
positive shutoff valve. Fuel lines must be of steel piping,
adequately secured and free from leaks. Do not use copper
piping on flexible lines as copper becomes hardened and
brittle and will break. Use black pipe on natural gas or
gaseous fuels, but not on gasoline or diesel fuels. Piping at
the engine should be a suitable flexible line that is
compatible with the fluid.
Positively no smoking!
2.
Check engine oil, fuel levels and gear box oil levels before
initial startup each day. Stay away from moving parts due to
the danger of becoming caught in moving parts. Avoid loose
jackets, shirts, sleeves and ties. Make sure all nuts and bolts
are secure. Keep power shields and guards in place. If
adjustment MUST be made while the unit is running, use
extreme caution around hot manifolds, moving parts, etc.
3.
Do not work with this equipment when mentally or physically
fatigued.
4.
Be careful not to touch the exterior of the engine, especially
the muffler and the area around it. It is hot enough to be
painful or cause injury.
5.
To prevent accidental starting, always remove the spark
plug or disconnect and ground the spark plug wire before
working on the engine or the equipment driven by the
engine.
6.
DO NOT RUN THE ENGINE IN AN ENCLOSED AREA!!
Exhaust gases contain carbon monoxide, which is an
odorless and deadly gas that will cause death if breathed too
long. If equipment is located in an enclosed area with an
