Water Pump 13
Operator's Manual
1.Select a firm, level site as near the water source as possible. Never exceed a suction lift (A) of 7.5 m (24 feet) or water will not flow.
Make sure pump will not move due to vibration and/or the pull from the weight of suction hose when full of water.
2.Total vertical discharge (B)is the distance the pump is capable of lifting water from the surface of the water to the discharge hose end. The distance must not exceed 29 m (95 ft.), otherwise no water will flow.
3.Make sure all hoses and pipe connections are air tight, and all hose coupling gaskets or
4.Keep prime port plug and pump drain plug tightly secured in place during operation.
5.Make sure strainer is in place.
6.Maximum pump efficiency is obtained by:
•Keeping hoses straight and avoiding kinks and sharp bends in hoses.
•Using shortest suction lift practical.
•Using as few connecters, elbows and adaptors as possible.
•Keeping the pump and associated equipment in good operating condition.

2.Remove prime port plug (A) and fill pump housing with water.
3.Replace prime port plug securely, making sure the gasket is on and in good condition.
With suction intake and strainer in the water to be pumped, start the engine. (See Starting the Engine.)
IMPORTANT
When priming the pump, operate the engine at half throttle. Should the engine be operated at full throttle during initial prime, water surges alternately followed by air pockets will cause over- speeding, resulting in possible engine damage.
NOTE
With engine running at approximately half throttle, the priming time depends upon the length of suction hose. Priming time can be as short as 30 seconds when lift is less than 1.5 m (5 feet) or as long as
