UNCRATING THE PUMP
Look carefully for shipping damage. lf damage of any sort is detected,
notify your dealer or the shipper. Remove all shipping blocks and clamps.
If the unit is engine-driven, it is very important that it be free to float on it's
springs.
DIESEL ENGINE AND 4-CYCLE ENGINE-DRIVEN
PUMPS
An engine manual for the specific engine is included. See Engine Manual
for fueling recommendations.
Diesel engines and 4-cycle engines have oil-filled crankcases which were
drained for shipment and must be refilled before operation of engine.
Read and follow all instructions in this Owner’s Manual and the Engine
Manual before performing any preparation, operation and maintenance
to the pump.

PUMP.
The pump depends upon water for internal lubrication; dry running will
quickly ruin the seal. Fill the pump cavity with water at the filler plug or
inlet nipple before starting the engine.
The pump is self priming to lifts of 25 feet (7.6 m). The time required to
prime is greatly affected by the lift. For the shortest priming time, place
the pump as close to the water source as possible.
ABC
OPERATING INSTRUCTIONS
1. Use a strainer on the end of the suction line.
2. Make sure that all hose and pipe connections are air tight. An air leak
in the suction line may prevent priming and will reduce the lift capacity
of the pump.
3. Place the pump as close to the liquid to be pumped as possible. Keep
the pump and engine on a level foundation. When the suction hose is
hanging down a steep bank or into a hole, the weight of the hose and
the liquid in it can pull the pump into the liquid. To prevent “walking”
and the possible loss of the pump, tie it down.
4. In freezing weather, always drain the liquid from the pump after use
by removing the drain plug. In freezing weather, crank the engine very
slowly so you can feel whether the pump is free to run before you crank
to start the engine. If the pump is frozen, thaw it out slowly. Do not use
fire to thaw the pump.
5. Maximum volume is achieved by:
a. keeping hoses as straight as possible, and avoiding kinks and
sharp bends.
b. making the vertical suction lift (distance from the water being
pumped to the pump suction port) as short as possible.
c. using correct diameter suction and discharge lines (larger
diameter provides lower friction).
d. using as few connectors, elbows and adapters as possible.
e. maintaining the pump and associated equipment in good
operating condition.
6. If flexible hose must be laid across a roadway, protect it with planking.
Instantaneous shut-off pressures, applied when a vehicle runs across
an unprotected line, can cause damage to the pump and hose.
7. The rubber check valve in the pump discharge seals off the pump to
retain liquid in the suction line so that the pump will start pumping
immediately after short periods of shutdown.
8. Check the level of oil in the engine crankcase before starting.
HOSE CONNECTIONS
Make certain that the suction hose connection is air tight. Air leakage at
the inlet will prevent the pump from priming and reduce pumping
efficiency. Discharge hose should be used at the outlet. Keep hoses as
short as possible; do not allow hoses to kink or be run over by vehicles;
check suction hoses for broken linings which will interfere with the flow.
If pipe is used, connect a short piece of flexible hose between the pipe
and the pump.
STRAINER
The strainer supplied with this pump is designed to fit a 2-inch hose. The
strainer orifices are sized to permit passage of solids that the unit is
designed to handle. Do not operate the pump without a strainer or use a
strainer with larger holes.
When the suction strainer is likely to clog with debris, tie it in a basket or
pail (A); prepare a bed of stones on which to rest the strainer (B); or tie the
strainer to a float so that it stays off the bottom (C).
