  • Page 17: Operation

    OPERATION SAFE OPERATING PRECAUTIONS To safely realize the full potential of this pump, you need a complete understanding of its operation and a certain amount of practice with its controls. Before operating the pump for the first time, please review the IMPORTANT SAFETY INFORMATION on page 5 and the chapter titled BEFORE OPERATION.

  • Page 18: Pump Placement

    OPERATION PUMP PLACEMENT For best pump performance, place the pump on a firm, level surface, and near the water level, and use hoses that are no longer than necessary. That will enable the pump to produce the greatest output with the least self-priming time. As head (pumping height) increases, pump output decreases.

  • Page 19: Suction Hose Installation

    Do not use a hose smaller than the pump’s suction port size. Minimum hose size: WB20XT=2 in (50 mm) WB30XT=3 in (80 mm) The suction hose should be no longer than necessary. Pump performance is best when the pump is near the water level and the hoses are short.

  • Page 20: Discharge Hose Installation

    OPERATION DISCHARGE HOSE INSTALLATION Use a commercially available hose and hose connector with the hose clamp provided with the pump (if necessary). It is best to use a short, large-diameter hose, because that will reduce fluid friction and improve pump output. A long or small-diameter hose will increase fluid friction and reduce pump output.

  • Page 21: Priming The Pump

    OPERATION PRIMING THE PUMP Before starting the engine, remove the filler cap from the pump chamber. Fill the pump chamber to the undersurface of the discharge port with water. Reinstall the filler cap and tighten it securely. Operating the pump dry will destroy the pump seal. If the pump has been operated dry, stop the engine immediately, and allow the pump to cool before priming.

  • Page 22: Starting The Engine

    OPERATION STARTING THE ENGINE 1. Prime the pump (see page 19). 2. Move the fuel valve lever to the ON position. FUEL VALVE LEVER 3. To start a cold engine, move the choke lever to the CLOSED position. To restart a warm engine, leave the choke lever in the OPEN position.
  • Page 23 OPERATION 5. Turn the ignition switch to the ON position. IGNITION SWITCH 6. Pull the recoil starter grip lightly until you fill resistance, and then pull briskly. Do not allow the recoil starter grip to snap back against the engine. Return it gently to prevent damage to the starter.

  • Page 46: Storage Precautions

    STORAGE STORAGE PRECAUTIONS If your pump will be stored with gasoline in the fuel tank and carburetor, it is important to reduce the hazard of gasoline vapor ignition. Select a well-ventilated storage area away from any appliance that operates with a flame, such as a furnace, water heater, or clothes dryer.

  • Page 47: Transporting

    TRANSPORTING If the pump has been running, allow the engine to cool for at least 15 minutes before loading the pump on the transport vehicle.
