  • Page 10: Preparation

    PREPARATION 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 11 Check the priming water. The pump chamber should be primed with full of water before operating. Priming water capacity: WT20X: 14.0 (3.70 US gal , 3.08 Imp gal) WT30X, WT40X: 15.0 (3.96 US gal , 3.30 Imp gal) Never attempt to operate the pump without priming water, or the pump will overheat.

  • Page 12: Pre-Operation Check

    PRE-OPERATION CHECK Check the engine oil level. 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. Check the oil level with the pump on a level surface and the engine stopped.
  • Page 13 Check the fuel level. 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. Avoid getting dirt or water in the fuel tank. Gasoline is extremely flammable and is explosive under certain conditions.
  • Page 14 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.
  • Page 15 Check the air cleaner element. Remove the wing nut and air cleaner cover. Check the air cleaner elements to be sure they are clean and in good condition. Clean or replace the elements if necessary (see page WING NUT AIR CLEANER COVER ELEMENT Never run the engine without the air cleaner.

  • Page 19: 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 20: Operation

    OPERATION Start the engine according to the procedures described in page Set the throttle at the desired speed. THROTTLE LEVER HIGH 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 21: Stopping The Engine

  • 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. 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.
  • 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) SIDE ELECTRODE 0.70 0.80 mm (0.028 0.031 in) 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 Servicing the pump casing After each use, clean the inside of the pump casing using the following procedure: Remove the pump drain plug from the pump cover using the wrench to drain the water inside. WRENCH PUMP DRAIN PLUG Loosen the pump cover knobs using the wrench.
  • Page 30 Install the O-ring on the pump cover, taking care not to damage the O-ring. Install the pump cover on the pump casing, and tighten the knobs handtight. Then, set the wrench to the knobs and finish tightening the knob securely. After tightening the pump cover knob, check the pump cover and pump casing to ensure that there is no water leakage.
  • Page 31 Spark arrester maintenance (applicable types) 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 32 WT20X Remove the four 5 mm screws from the muffler protector and remove the muffler protector. Remove the 4 mm screw from the spark arrester, and remove the spark arrester from the muffler. 5 mm SCREWS MUFFLER PROTECTOR 4 mm SCREW...
  • Page 33 Use a brush to remove carbon deposits from the spark arrester screen. Be careful to avoid damaging the screen. SPARK ARRESTER SCREEN The spark arrester must be free of breaks and holes. Replace it if necessary. Install the spark arrester and the muffler protector in the reverse order of disassembly.

  • Page 34: 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 35 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 36: Troubleshooting

    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. When the pump cannot pump the water; Is the pump fully primed?
