I. WATER PUMP SAFETY
To ensure safe operation -
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.
l Operate the pump on a level surface. If the engine is tilted, fuel spillage
may result.
l ?o prevent fire hazards and to provide adequate ventilation, keep the
pump at least 1 meter (3 feet) away from building walls and other equipment during operation. Do not place flammable objects close to
the pump.
l Do not allow children to operate the pump. Keep children and pets
away from the area of operation.
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.
- Refuel in a well-ventilated area with the engine stopped. Do not smoke or allow flames or sparks in the area where the engine is refueled or where gasoline is stored.
- Do not overfill the fuel tank1 there should be no fuel in the filler neck 1. 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 gas
contains poisonous carbon monoxide gas; exposure can cause loss of consciousness 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.
l A spark arrester is available as an optional part for this pump. It is illegal
in some areas to operate an engine without a spark arrester. Check local laws and regulations before operating.
l Exhaust gas contains poisonous carbon monoxide. Avoid inhalation of
exhaust gas. Never run the pump in a closed garage or confined area.

3. PRE-OPERATION CHECK
1. Suction hose
Use a commercially available hose, hose connector, and hose bands. The suction hose must be of reinforced, non-collapsible wall or wire braided
hose to prevent suction collapse. The suction hose length should not be longer than necessary, as the pump performance is best when the pump is not far above the water level. Self-priming time is also proportional to the suction hose length. Using a longer suction hose will increase the self­priming time.
The strainer is provided with the pump and should be attached to the end of the suction hose with a band as shown.
Always install the strainer on the end of the suction hose before pumping. The strainer will prevent debris from entering the pump that can cause clogging or pump damage.

STRAINER
2. Discharge hose
Use a commercially available hose, hose connector, and hose band. A short, large-diameter hose is most efficient. A long or small-diameter hose increases fluid friction and reduces pump output.
Tighten the hose band securely to prevent the hose from disconnecting under high pressure.

3. Engine oil

l Engine oil is a major factor affecting engine performance and service
I
life. Nondetergent oils and 2-stroke oils are not recommended because they have inadequate lubricating characteristics.
l Check the oil level with the pump on a level surface and 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 SG, SF/CC, CD. Motor oils classified SG, SF/CC, CD will show this designation on the container. SAE lOW/30 is recommended for general, all-temperature use.
Other viscosities shown in the chart
may be used when the average tempera­ture in your area is within the indicated

range.
1. Remove the oil filler cap/dipstick and wipe it clean.
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 the
recommended oil.
The Oil Alert System will automatically stop the engine before the oil level falls below the safe limit. However, to avoid the inconvenience of an unexpected shutdown, it is advisable to visually inspect the oil level regularly.

Fuel Recommendation

1. Remove the filler cap check fuel level.
2. Refill the tank if the fuel level is low. Do not fill above the shoulder of the fuel strainer.
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 area where the engine is refueled or where gasoline is stored.
l Do not overfill the fuel tank( there should be no fuel in the filler neck 1.
After refueling, make sure the tank cap is closed properly and secqrely. 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 Avoid repeated or prolonged contact with skin or breathing of vapor. l KEEP OUT OF REACH OF CHILDREN.

-FUFL FILLER CAP
Use gasoline with a pump octane ratinng of 86 or higher
We recommend unleaded gasoline because it produces fewer engine and spark plug deposits and extends exhaust system life.
Never use stale or contaminated gasoline or oil/gasoline mixture. Avoid getting dirt or water in the fuel tank.

Occasionally you may hear light “spark knock” or “pinging” 1 metallic rapping noise ) while operating under heavy loads. This is no cause for concern.
If spark knock or pinging occurs at a steady engine speed, under normal load, change brands of gasoline. If spark knock or pinging persists, see an authorized Honda water pump dealer.
j-iciq
Running the engine with persistent spark knock or pinging can cause
engine damage.
Running the engine with persistent spark knock or pinging is misuse, and
the Distributor’s Limited Warranty does not cover parts damaged by
misuse.
Oxygenated Fuels Some gasolines are being blended with alcohol or an ether compound to increase the octane. These gasolines are collectively referred to as oxygenated fuels. Some areas of the United States use oxygenated fuels
to help meet clean air standards.
If you use an oxygenated fuel, be sure its pump octane rating is 86 or
higher.
Ethanol 1 ethyl or grain alcohol 1 Gasoline containing more than 10% ethanol by volume may cause starting and/or performance problems. Gasoline containing ethanol may be marketed under the name “Gasohol”.
Methanol ( methyl or wood alcohol) Gasoline containing methanol must contain cosolvents and corrosion inhibitors to protect the fuel system. Gasoline containing more than 5% methanol by volume may cause starting and/or performance problems and may damage metal, rubber, and rjlastic parts of your fuel system.
MTBE (methyl tertiary butyl ether)
You may use gasoline containing up to 15% MTBE by volume.
Before using an oxygenated fuel, try to confirm the fuel’s contents. Some
states (provinces in Canada) require this information to be posted on the
pump. If you notice any undersirable operating symptoms, switch to a
convertional unleaded gasoline. Fuel system damage or performance
problems resulting from the use of an oxygenated fuel are not the responsibility or Honda and are not covered under warranty.
jTimEq
Oxygenated fuels can damage paint and plastic. Be careful not to spill fuel when filling your fuel tank. Damage caused by spilled fuel is not convered under warranty.

5. Air cleaner
Remove the wing nut, washer and air cleaner cover. Check the air cleaner element to be sure it is clean and in good condition. Clean or replace the element if necessary (p. 18 1.

6. Priming water
The pump chamber should be completely filled before operating.
[NOTICE 1

Do not operate the pump without priming water or the pump will overheat. Operating the pump dry will destroy the pump seal. If the unit has been operated dry, stop the engine immediately and allow the pump

to cool before adding priming water.
