  • Page 16: 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 17: Pump Placement

    OPERATION PUMP PLACEMENT For best pump performance, place the pump 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. The length, type, and size of the suction and discharge hoses can also significantly affect pump output.

  • Page 18: Suction Hose Installation

    OPERATION SUCTION HOSE INSTALLATION Use a commercially available 1.5 inch diameter hose and hose connector with the hose clamp provided with the pump (if necessary). Most hoses come with the connectors already installed. The suction hose must be reinforced with a noncollapsible wall or braided wire construction and cannot contain any perforations.

  • Page 19: Discharge Hose Installation

    OPERATION DISCHARGE HOSE INSTALLATION Use a commercially available hose HOSE CONNECTOR and hose connector and clamp 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.
  • Page 20 OPERATION If the discharge hose must run across a roadway, the hose should cross the roadway perpendicular to traffic flow. Also, heavy boards should be placed next to the hose so the motor vehicle weight does not shut off the discharge as vehicles cross over the hose. BOARDS DISCHARGE HOSE Driving over a discharge hose while the pump is running, or even...

Allow the water to drain from the pump chamber, and then reinstall the drain plug. 6.After the pump is clean and dry, touch up any damaged paint, and coat areas that may rust with a light film of oil.

  • Page 43: Fuel

    STORAGE Fuel Depending on the region where you operate your equipment, fuel formulations may deteriorate and oxidize rapidly. Fuel deterioration and oxidation can occur in as little as 30 days and may cause damage to the carburetor and/or fuel system. Please check with your servicing dealer for local storage requirements.
  • Page 44 STORAGE Adding a Fuel Stabilizer to Extend Fuel Storage Life Short Term Storage (30-90 days) If your equipment will not be used for 30-90 days, we recommend the following to prevent fuel-related problems. 1.Add fuel stabilizer following the manufacturer’s instructions.
