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

because of 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

exhaust line to the outside, regularly check the exhaust

system for leaks. Be sure the area is well ventilated.

7. If the gas engine is equipped with a spark arrester screen in

the muffler, it should be inspected for wear periodically and

replaced when necessary.

DIAPHRAGM PUMPS Specifications Information and Repair Parts Manual x Diaphragm Pumps CLEARING JAM-UP If large solids or an accumulation of sand or other sediment becomes lodged in the pump well (Ref. No. A3) preventing the plunger arm (Ref. No. A2) from making a full stroke, the pump will either stall or the crank (Ref. No. P5) will slip on the output shaft (Ref. No. G8). The pump is designed to react this way to prevent severe internal damage.
