PUMP SAFETY
IMPORTANT SAFETY INFORMATION
Honda WT20X, WT30X, and WT40X pumps are designed to pump only
fresh 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.

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.

Oil Alert
The Oil Alert
System
system is designed to prevent engine damage caused
by an insufficient amount of oil in the crankcase. Before the oil level in
the crankcase can fall below a safe limit, the Oil Alert system will
automatically stop the engine (the ignition switch will remain in the
ON position).
If the engine stops and will not restart, check the engine oil level (page
) before troubleshooting in other areas.29

BEFORE OPERATION
ARE YOU READY TO GET STARTED?
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.
11
BEFORE OPERATION
IS YOUR PUMP READY TO GO?
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.
12
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 ).
Check that the hose connectors and clamps are securely installed
(see pages and ).
Check that the strainer is in good condition and is installed on the
suction hose (see page ).

Check the oil level (see page ). To avoid the inconvenience of an
unexpected shutdown by the Oil Alert system, always check the
engine oil level before startup.
Check the air filter (see page ). A dirty air filter will restrict air flow
to the carburetor, reducing engine and pump performance.
Check the fuel level (see page ). Starting with a full tank will help
to eliminate or reduce operating interruptions for refueling.

SAFE OPERATING PRECAUTIONS
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
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.

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.

OPERATION
PUMP PLACEMENT
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
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.

OPERATION
SUCTION HOSE INSTALLATION
Use a commercially available hose and hose connector with the hose
clamp provided with the pump (if necessary). Most hoses come with
the connectors already installed. The suction hose must be reinforced
with a noncollapsible wall or braided wire construction and cannot
contain any perforations.
The suction hose should be no longer than necessary. Pump
performance is best when the pump is near the water level and the
hoses are short.
Use a hose clamp to securely fasten the hose connector to the suction
hose in order to prevent air leakage and loss of suction. Verify that the
hose connector sealing washer is in good condition.
Install the strainer (provided with the pump) on the other end of the
suction hose, and secure it with a hose clamp. The strainer will help to
prevent the pump from becoming clogged or damaged by debris.
Never operate the pump without the strainer installed.
Securely tighten the hose connector on the pump suction port.
