Page 3: Safety Instruction
SAFETY INSTRUCTION To ensure safe operation Honda water pump is designed to give safe and dependable service if operated according to in- structions. Read and understand the Owner’s Manual be- fore operating the water pump. Failure to do so could result in personal injury or equipment dam- age.
Page 4 To ensure safe operation 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 refueling area or where gasoline is stored. Do not overfill the tank.

Page 9: Pre-Operation For Starting
PRE-OPERATION FOR STARTING 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.
Page 10 Nondetergent or vegetable oils are not recommended. Be sure to check the engine on a level surface with the engine stopped. Use Honda 4-stroke oil, or an equiva- SAE Viscosity Grades lent high detergent premium quality motor oil certified to meet or exceed U.S.
Page 11 Oil Alert System (Where equipped) The Oil Alert 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 auto- matically stop the engine (the engine switch will remain in the ON position).
Page 12 Check the fuel level. Use automotive gasoline (unleaded or lowleaded is preferred to minimize combustion chamber deposits). Never use an oil/gasoline mixture or dirty gasoline. Avoid getting dirt, dust or water in the fuel tank. Gasoline is extremely flammable and is explosive under certain conditions.
Page 13 Gasolines containing alcohol If you decide to use a gasoline containing alcohol (gasohol), be sure it’s octane rating is at least as high as that recommended by Honda. There are two types of ‘‘gasohol’’: one containing ethanol, and the other containing methanol. Do not use gasohol that contains more than 10% ethanol.
Page 14 Check the air cleaner element. Remove the wing nut, washer and air cleaner cover. Check the element for dirt or obstruction. Clean the element if necessary (see page AIR CLEANER COVER AIR CLEANER ELEMENT Never run the engine without the air cleaner. Rapid engine wear will result from contaminants, such as dust and dirt, being drawn through the carburetor, into the engine.
Page 15: Starting The Engine
STARTING THE ENGINE Turn the fuel valve ON. Close the choke lever. Do not use the choke if the engine is warm or the ambient temperature is high. CHOKE LEVER FUEL VALVE CLOSE CLOSE Turn the engine switch to the ON position. ENGINE SWITCH...
Page 16 Move the throttle lever slightly to the left. HIGH THROTTLE LEVER Pull the starter grip lightly until resistance is felt, then pull it briskly. Do not allow the starter grip to snap back against the engine. Return it gently to prevent damage to the starter. STARTER GRIP...
Page 17: High Altitude Operation
High altitude performance can be improved by specific modifications to the carburetor. If you always operate the pump at altitudes higher than 1,500 m (5,000 feet) above sea level, have your authorized Honda dealer perform these carburetor modifications. Even with suitable carburetor jetting, engine horsepower will decrease approximately 3.5 % for each 300 m (1,000 foot) increase in altitude.
Page 18: Operation
OPERATION Never use the pump for muddy water, rejected oil, wine, etc. As the engine warms up, gradually open the choke. CHOKE LEVER OPEN OPEN Set the throttle at the desired speed. THROTTLE LEVER HIGH...
Page 19: Stopping The Engine
STOPPING THE ENGINE Move the throttle lever fully to the right. Turn the engine switch to the OFF position. THROTTLE LEVER ENGINE SWITCH Turn the fuel valve OFF. FUEL VALVE To stop the engine in an emergency, turn the engine switch to the OFF position.
Page 20: Maintenance
If the pump has been used with sea water, etc., pump clean, fresh water immediately afterward to reduce corrosion or remove sediment. Use genuine Honda parts or their equivalent for maintenance or repair. Replacement parts which are not of equivalent quality may damage the pump.
Page 21: Maintenance Schedule
Service more frequently when used in dusty areas. These items should be serviced by your servicing dealer, unless you have the proper tools and are mechanically proficient. Refer to Honda shop manual for service procedures. For commercial use, log hours of operation to determine proper maintenance...
Page 22 Changing oil Drain the oil while the engine is still warm to assure rapid and complete draining. Remove the oil filler cap/dipstick and the drain plug, then drain the oil. Install the drain plug securely using a new sealing washer. Refill with the recommended oil (see page ) to the specified level.
Page 23 Air cleaner service A dirty air cleaner will restrict air flow to the carburetor. To prevent carburetor malfunction, service the air cleaner regularly. Service more frequently when operating the pump in extremely dusty areas. Do not use gasoline or low flash point solvents for cleaning. They are flammable and explosive under certain conditions.
Page 24 Spark plug service Recommended spark plug: BPR6ES(NGK) W20EPR-U(DENSO) To ensure proper engine operation, the spark plug must be properly gapped and free of deposits. Remove the spark plug cap. If the engine has been running, the muffler will be very hot. Be careful not to touch the muffler.
Page 25 Check that the spark plug washer is in good condition, and thread the spark plug in by hand to prevent cross-threading. If installing a new spark plug, tighten 1/2 turn after the spark plug seats to compress the washer. If reinstalling a used spark plug, tighten 1/8 1/4 turn after the spark plug seats to compress the washer.
Page 26 Spark arrester maintenance (optional part) 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. Allow it to cool before proceeding. Remove the two 8 mm nuts, and remove the muffler. Remove the four 5 mm self-tapping screws, and remove the muffler protector from the muffler.
Page 27: Transporting/Storage
TRANSPORTING/STORAGE To avoid severe burns or fire hazards, let the engine cool before transporting the pump or storing it indoors. When transporting the pump, turn the fuel valve to the OFF position, and keep the pump level to prevent fuel spillage. Spilled fuel or fuel vapor may ignite.
Page 28 Change the engine oil. Remove the spark plug, and pour about a tablespoon of clean engine oil into the cylinder. Crank the engine several revolutions to distribute the oil, then reinstall the spark plug. Pull the starter grip until resistance is felt. Continue pulling until the notch on the starter pulley aligns with the hole on the recoil starter (see illustration below).
Page 29: Troubleshooting
Is the spark plug in good condition? Remove and inspect the spark plug. Clean, readjust gap and dry the spark plug. Replace it if necessary. If the engine still does not start, take the pump to an authorized Honda dealer.
Page 30 Is the pump fully primed? Is the strainer clogged? Are the hose bands installed securely? Are the hose damaged? Is the suction head too high? If the pump still does not operate, take the pump to an authorized Honda dealer.
