Honda WB20XT and WB30XT pumps are 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.
Most injuries or property damage 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 store gasoline in an approved container. Make sure that any spilled fuel has been wiped up before starting the engine.
5
PUMP SAFETY
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 contains poisonous carbon monoxide, a colorless and odorless gas. Breathing carbon monoxide can cause loss of consciousness and may lead to death.
If you run the pump in an area that is confined, or even partly enclosed, the air you breathe could contain a dangerous amount of exhaust gas.
Never run the engine inside a closed garage, house, or confined area.

PUMP SAFETY
The labels shown here contain important safety information. Please read them carefully. These labels are considered permanent parts of your pump. If a label comes off or becomes hard to read, contact an authorized Honda servicing dealer for a replacement.

CONTROLS
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 O F F p o s i t i o n t o p r e v e n t carburetor flooding and to reduce the possibility of fuel leakage.
The ignition switch controls the ignition system.
The ignition switch must be in the ON position for the engine to run.
Turning the ignition switch to the OFF position stops the engine.

CONTROLS
The choke lever opens and closes the choke valve in the carburetor.
The CLOSED position enriches the fuel mixture for starting a cold engine.
The OPEN position provides the correct fuel mixture for operation after starting, and for restarting a warm engine.
The throttle lever controls engine speed.
Moving the throttle lever in the directions shown makes the engine run faster or slower.
Pump output is controlled by adjusting the throttle lever. At maximum throttle position, the pump will deliver the highest output volume. Moving the throttle lever toward the idle position will decrease the output volume of the pump.

Your safety is your responsibility. A little time spent in preparation will significantly reduce your risk of injury.
Knowledge
Read and understand this manual. Know what the controls do and how to operate them.
Familiarize yourself with the pump and its operation before you begin pumping. Know what to do in case of emergencies.
Be sure of what you are pumping. This pump is designed to pump only fresh water that is not intended for human consumption.
13
BEFORE OPERATION
For your safety, and to maximize the service life of your equipment, it is very important to take a few moments before you operate the pump to check its condition. Be sure to take care of any problem you find, or have your servicing dealer correct it, before you operate the pump.
Improperly maintaining this pump, or failing to correct a problem before operation, could cause a malfunction in which you could be seriously injured.
Always perform a preoperation inspection before each operation, and correct any problem.
To prevent a possible fire, 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.
Before beginning your preoperation checks, be sure the pump is on a level surface and the ignition switch is in the OFF position.
Check the General Condition of the Pump
Look around and underneath the pump for signs of oil or gasoline leaks.
Remove any excessive dirt or debris, especially around the engine muffler and recoil starter.
Look for signs of damage.
Check that all nuts, bolts, screws, hose connectors and clamps are tightened.
14
BEFORE OPERATION
Check the Suction and Discharge Hoses
Check the general condition of the hoses. Be sure the hoses are in serviceable condition before connecting them to the pump. Remember that the suction hose must be reinforced construction to prevent hose collapse.
Check that the sealing washer in the suction hose connector is in good condition (see page 18 ).
Check that the hose connectors and clamps are securely installed (see pages 18 and 19 ).
Check that the strainer is in good condition and is installed on the suction hose (see page 18 ).
Check the Engine
Check the engine oil level (see page 31 ). Running the engine with a low oil level can cause engine damage.
Check the air filter (see page 34 ). A dirty air filter will restrict air flow to the carburetor, reducing engine and pump performance.
Check the fuel level (see page 29 ). Starting with a full tank will help to eliminate or reduce operating interruptions for refueling.
15
To safely realize the full potential of this pump, you need a complete understanding of its operation and a certain amount of practice with its controls.
Before operating the pump for the first time, please review the
IMPORTANT SAFETY INFORMATION on page 5 and the chapter titled BEFORE OPERATION.
For your safety, avoid starting or operating the engine in an enclosed area, such as a garage. Your engine’s exhaust contains poisonous carbon monoxide gas that can collect rapidly in an enclosed area and cause illness or death.
Exhaust contains poisonous carbon monoxide gas that can build up to dangerous levels in closed areas. Breathing carbon monoxide can cause unconsciousness or death.
Never run the engine in a closed, or even partly closed area where people may be present.
Pump only fresh 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.
16
OPERATION
For best pump performance, place the pump near the water level, and use hoses that are no longer than necessary. That will enable the pump to produce the greatest output with the least self-priming time.
As head (pumping height) increases, pump output decreases. The length, type, and size of the suction and discharge hoses can also significantly affect pump output.
Discharge head capability is always greater than suction head capability, so it is important for suction head to be the shorter part of total head. The maximum available suction head will vary based on the operating conditions. However, the suction head can never exceed 26 feet (8 meters) and should always be kept as low as possible.
Minimizing suction head (placing the pump near the water level) is also very important for reducing self-priming time. Self-priming time is the time it takes the pump to bring water the distance of the suction head during initial operation.
