  • Page 11: Pre-Operation Check

    PRE-OPERATION CHECK 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 12 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. Tighten the hose band securely to prevent the hose from disconnecting under high pressure.
  • Page 13 OIL FILLER NECK OIL FILLER CAP UPPER LEVEL RECOMMENDED OIL Use 4-stroke motor oil that meets or exceeds the requirements for API service classification SE or later (or equivalent). Always check the API service label on the oil container to be sure it includes the letters SE or later (or equivalent).
  • Page 14 Check the fuel level. Remove the fuel tank cap and the check the fuel level. Refill the tank if the fuel level is low. Use automotive unleaded gasoline with a Research Octane Number of 91 or higher (a Pump Octane Number of 86 or higher). Never use stale or contaminated gasoline or an oil/gasoline mixture.
  • Page 15 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 16 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 WING NUT AIR CLEANER COVER WASHER 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.

HIGH THROTTLE LEVER Pull the starter grip lightly until you feel resistance, then pull it briskly in the direction of the arrow as shown below. Do not allow the starter grip to snap back against the engine. Return it gently to prevent damage to the starter.
  • Page 19 Let the engine warm up for several minutes. If the choke lever has been moved to the CLOSE position, move it gradually to the OPEN position as the engine warm up. CHOKE LEVER CLOSE OPEN OPEN...

  • Page 20: Carburetor Modification For High Altitude Operation

    High altitude performance can be improved by specific modifications to the carburetor. If you always operate your water pump at altitudes above 1,500 meters (5,000 feet), have your authorized Honda servicing dealer perform this carburetor modification. This engine, when operated at high altitude with the carburetor modifications for high altitude use, will meet each emission standard throughout its useful life.

  • Page 21: Operation

  • Page 22: Stopping The Engine

    STOPPING THE ENGINE To stop the engine in an emergency, turn the engine switch to the OFF position. To stop the engine in normal circumstances: 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.

  • Page 23: 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 24: 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 intervals.
  • Page 25 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 26 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 27 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. If the engine has been running, the muffler will be very hot. Be careful not to touch the muffler.
  • Page 28 Measure the plug gap with a feeler gauge. Correct as necessary by bending the side electrode. The gap should be: 0.70 0.80 mm (0.028 0.031 in) 0.70 0.80 mm (0.028 0.031 in) SIDE ELECTRODE SEALING WASHER Check that the sealing washer is in good condition, and thread the spark plug in by hand to prevent cross-threading.
  • Page 29 Spark arrester maintenance (optional parts) 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. The spark arrester must be serviced every 100 hours to maintain its efficiency.

  • Page 30: 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 31 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 you feel resistance. Continue pulling until the notch on the starter pulley aligns with the hole on the recoil starter (see illustration below).

  • Page 32: 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 water pump to an authorized Honda dealer.
  • Page 33 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 water pump to an authorized Honda dealer.
