Specic 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:
• Use gasoline only as a fuel, never as a cleaning uid.
• Always use an approved container to hold or store gasoline. Never
store gasoline in familiar containers such as milk gallons or soda pop
bottles
• Never store gasoline near a heater or an open ame.
• When storing or using gasoline, make sure container is out of the
reach of children.
• Never add gasoline to a running or hot engine. Spilled gasoline on
a hot engine may cause a re or an explosion. Fill gasoline tank
outdoors and wipe up any spills.
• Have a re extinguisher nearby. Be sure extinguisher is in operating
condition – check the pressure gauge or indicator. Be familiar with
its proper use. Consult the local re department for the correct
type of extinguisher for your application. Extinguishers rated ABC
by the National Fire Protection Association are appropriate for all
applications.
DESCRIPTION
These diaphragm pumps are high capacity, self-priming (to 25 ft. lift), portable units shipped completely assembled (except for handle). The pumps are used
for operation with uids mixed with abrasive solids such as sand, silt, mud, sludge and waste. Not for use with pumping cement or mortar. Handles liquids from
40º to 180º F (4º to 82 º C). Pump is capable of handling solids up to 1-5/8” diameter. For use with water and other non-ammable uids compatible with pump
component materials.
• On permanent installations, be sure all fuel supplies have a positive
shuto󰀨 valve. Fuel lines must be of steel piping, adequately secured
and free from leaks. Do not use copper piping on exible 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 exible line that is
compatible with the uid.
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 mu󰀪er
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 mu󰀪er, it
should be inspected for wear periodically and replaced when necessary.
