IMPORTANT SAFETY INFORMATION
This water pump is designed to pump only water that is not intended for
human consumption, and other uses can result in injury to the operator
or damage to the pump and other property.
Always make a pre-operation inspection before you start the engine.
You may prevent an accident or equipment damage.
Most accidents can be prevented if you follow all instructions in this
manual and on the pump. The most common hazards are discussed
below, along with the best way to protect yourself and others.
Operator Responsibility
It is the operator's responsibility to provide the necessary safeguards to
protect people and property. Know how to stop the pump quickly in
case of emergency.
If you leave the pump for any reason, always turn the engine off.
Understand the use of all controls and connections.
Be sure that anyone who operates the pump receives proper instruction.
Do not let children operate the pump. Keep children and pets away from
the area of operation.
Pump Operation
Pump only water that is not intended for human consumption. Pumping
flammable liquids, such as gasoline or fuel oils, can result in a fire or
explosion, causing serious injury. Pumping sea water, beverages, acids,
chemical solutions, or any other liquid that promotes corrosion can
damage the pump.
Refuel With Care
Gasoline is extremely flammable, and gasoline vapor can explode.
Refuel outdoors, in a well-ventilated area, with the engine stopped and
the pump on a level surface. Do not fill the fuel tank above the fuel
strainer shoulder. Never smoke near gasoline, and keep other flames
and sparks away. Always stored gasoline in an approved container.
7
Make sure that any spilled fuel has been wiped up before starting the
engine. After refueling, make sure the tank cap closed properly and
securely.
Hot Exhaust
The muffler becomes very hot during operation and remains hot for a
while after stopping the engine. Be careful not to touch the muffler while
it is hot. Let the engine cool before transporting the pump or storing it
indoors.
To prevent fire hazards, keep the pump at least 3 feet (1 meter) away
from building walls and other equipment during operation. Do not place
flammable objects close to the engine.
Carbon Monoxide Hazard Exhaust gas contains poisonous carbon
monoxide. Avoid inhalation of exhaust gas. Never run the engine in a
closed garage or confined area.

3. CONTROLS
Fuel Valve Lever
The fuel valve opens and closes the passage between the fuel tank and the carburetor.
The fuel valve lever must be in the ON position for the engine to run.
When the engine is not in use, leave the fuel valve lever in the OFF position to prevent
carburetor flooding and to reduce the possibility of fuel leakage.
Throttle Lever
The throttle lever controls engine speed.
Moving the throttle lever in the directions shown makes the engine run faster or slower.
Engine Switch
The engine switch enables and disables the ignition system.
The engine switch must be in the ON position for the engine to run.
Turning the engine switch to the OFF position stops the engine.

The OPEN position provides the correct fuel mixture for operation after starting, and for
restarting a warm engine.
Some engine applications use a remotely-mounted choke control rather than the
engine-mounted choke lever shown here.
