Honda Power Equipment WB20X User Manual
Thank you for purchasing a Honda water pump.
This manual covers the operation and maintenance of WBZOX and WB3OX
water pumps. All information in this publication is based on the latest
product information available at the time of approval for printing.
Honda Motor Co., Ltd. reserves the right to make changes at any time without
notice and without incurring any obligation.
The illustrations in this book are based on the WB20X unless otherwise noted.
No part of this publication may be reproduced without written permission.
This manual should be considered a permanent part of the pump and should
remain with the pump if it is resold.
Pay special attention to statements preceded by the following words:
l For safety, never pump flammable or corrosive liquids such as gasoline or
acid. Also, to avoid pump corrosion, never pump sea water, muddy water,
chemical solutions, or caustic liquids such as used oil, wine, or milk.
mzml Indicates a strong possibility of severe personal injury or death if
instructions are not followed.
CAUTION: Indicates a possibility of personal injury or equipment damage if
instructions are not followed.

vice if operated according to instructions. Read and understand the Owner’s
Manual before operating the pump. Failure to do so could result in personal in-
jury or equipment damage.
It is illegal in some areas to operate an engine without a U.S.D.A. qualified
spark arrester; check local laws and regulations. An optional spark arrester for
this pump is available from your authorized Honda pump dealer.

1. SAFETY INSTRUCTIONS
To ensure safe operation-
. For safety, never pump flammable or corrosive liquids such as gasoline or
acid. Also, to avoid pump corrosion, never pump sea water, muddy water,
chemical solutions, or caustic liquids such as used oil, wine, or milk.
l
Place the pump on a firm, level surface. If the pump is tilted or overturned,
fuel spillage may result.
l
To prevent fire hazards and to provide adequate ventilation, keep the pump
at least 1 meter (3 feet) away from buildings and other equipment during
operation. Do not place flammable objects close to the pump.
l
Children and pets must be kept away from the area of operation due to a
possibility of burns from hot engine components.
l
Know how to stop the pump quickly, and understand the operation of all
controls. Never permit anyone to operate the pump without proper
instructions.
l
Gasoline is extremely flammable and is explosive under certain conditions.
l
Refuel in a well-ventilated area with the engine stopped. Do not smoke or
allow flames or sparks in the refueling area or where gasoline is stored.
l
Do not overfill the fuel tank. After refueling, make sure the tank cap is closed properly and securely.
l
Be careful not to spill fuel when refueling. Spilled fuel or fuel vapor may ignite. If any fuel is spilled, make sure the area is dry before starting the
engine.
l
Never run the engine in an enclosed or confined area. Exhaust contains
poisonous carbon monoxide gas;
exposure can cause loss of con-
sciousness and may lead to death.
l
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 storing the pump indoors.

3. PREPARATION
1. Connect the suction hose.
.Use commercially available hose, hose connector, and hose bands. The suction hose must be of reinforced, noncollapsible construction. Suction hose
length should not be longer than necessary, as pump performance is best
when the pump is not far above the water level. Self-priming time is also proportional to hose length.
The strainer that is provided with the pump should be attached to the end of
the suction hose with a band, as shown.
CAUTION: Always install the strainer on the end of the suction hose before
pumping. The strainer will exclude debris that can cause clogging or impeller
damage.
NOTE: Tighten the hose connector and bands to prevent air leakage and loss
of suction. A loosely connected suction hose will reduce pump performance
and self-priming ability.
2. Connect the discharge hose.
Use a commercially available hose, hose connector, and hose band. A short,
large-diameter hose is most efficient. Long or small-diameter hose increases
fluid friction and reduces pump output.
NOTE: Tighten the hose band securely to prevent the hose NOTE: Tighten the hose band securely to prevent the hose
ing under high pressure. ing under high pressure.

3. Check the engine oil level.
CAUTION:
l
Engine oil is a major factor affecting engine performance and service life.
Nondetergent oils and 2-stroke oils, are not recommended because they
have inadequate lubricating characteristics.
l
Be sure to check the engine on a level surface with the engine stopped.
Use Honda 4-stroke oil, or an equivalent
high detergent, premium quality motor
oil certified to meet or exceed U.S.
automobile manufacturer’s requirements
for Service Classification SE or SF,
(Motor oils classified SE or SF will show
this designation on the container.)
SAE low-40 is recommended for gene-
ral, all-temperature use.

2. Insert the filler cap/dipstick into the oil filler neck, but do not screw it in.
3. If the level is low, fill to the top of the oil filler neck with recommended
oil.
CAUTION: Running the engine with insufficient oil can cause serious engine
damage.
