Specific Safety Information for Gasoline 
Engine Driven Pumps 

1. Carefully read the instruction manuals supplied by
the engine manufacturer before attempting to assem-
ble/disassemble or operate the engine or any other 
part. The “Warning” and “Caution” statements in this 
manual signal potential hazardous conditions to the 
operator or equipment. Know when these conditions 
can exist. Take necessary steps to protect personnel 
as well as equipment. 

WARNING 

Gasoline is a highly combustible fuel. Use it with care! 
The improper use, handling and/or storage of gaso-
line can be dangerous. Help prevent accidents by 
following these safety rules: 

a. Use gasoline only as 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 extinguish-
er 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 appropriated for all applications. 
g. On permanent installations, be sure all fuel  

 

 

supplies have a positive shut-off valve. Fuel lines 
must be of steel piping, adequately secured and free 
from leaks. Do not use copper piping or 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 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 mov-
ing 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 equipement 
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. 

Specific Safety Information for Electric Motor 
Driven Pump 

1. This unit is not waterproof and is not intended to be
used in potentially wet locations. The motor is de-
signed to be used in a clean, dry location with access 
to an adequate supply of cooling air. Ambient temper-
ature around the motor should not exceed 104° F 
(40° C). For outdoor installations, motor must be pro-
tected by a cover that does not block air flow to and 
around the motor. This unit is not weatherproof nor is 
it able to be submersed in water. 
2. When wiring an electrically driven pump, follow all
electrical and safety codes, as well as the most re-
cent United States National Electrical Code (NEC) 
and the Occupational Safety and Health Act (OSHA). 

        WARNING 

Risk of electrical shock!  Never connect the green 
(or green and yellow) wire to a live terminal 

3. To reduce the risk of electric shock, the motor must
be securely and adequately grounded!  This can be 
accomplished by either (1) inserting plug (portable) 
directly into a properly installed and grounded
