OPERATION OF THE TRASH PUMP
Starting the Engine
WARNING!
This pump is designed to pump non-volitile, non-
flammable liquids containing specified entrained
solids. Do not attempt to pump volitile, flam-
mable, or corrosive liquids.
CAUTION!
Never operate pump unless there is liquid in the
pump casing. The pump will not prime when dry.
Extended operation of dry pump will destroy the
seal assembly.
WARNING!
Never tamper with governor to gain power. The
maximum continuous operating speed of 3500
RPM is set at the factory.
Priming
Never operate pump unless there is water in
the pump housing.
Add liquid to the pump casing when:
1
. The pump is being put into service for the first
time.
2
. The pump has not been used for a considerable
length of time.
3
. The liquid in the pump casing has evaporated.
To fill the pump, remove the pump fill plug at the top
of the pump casing. Add clean liquid until the casing
is filled past the flapper on the suction valve of the
pump and replace the cover or plug. Insure the
flapper seals and water remains in the pump.
Run the engine at maximum governed speed
during the priming cycle. With a suction lift of 5
to 10 feet the pump should prime within 1 minute.
The maximum suction lift of 15 feet (at sea level)
should require no more than 2 minutes for the initial
prime. If the pump does not prime within five min-
utes, shut off the engine and trouble shoot.
The suction hose should be a minimum of 8 feet
long and have a wire filter screen, to prevent hard
solid objects from entering the pump and damaging
the impellor and seals.
Priming is indicated by quieter operation. The
pump may not prime immediatelybecause the
suction line must first fill with liquid. If the pump
fails to prime in five minutes check the suction
hose for leaks.
LEAKING
No leakage should be visible at pump mating
surfaces, or at pump connections and fittings.
Keep all connections and fittings tight to ensure
maximum pump efficiency. Use a lubricant on
suction hose threads to assist in sealing suction
hose.
LIQUID TEMPERATURE
The maximum liquid temperature of the pump is
110 degrees F. Overheating can occur if the
pump is operated with the suction or discharge
valves closed. If overheating occurs allow for the
pump to cool before servicing it. Refill the pump
case with cool liquid.
STRAINER
If a strainer has been shipped or installed by the
user, check it regularly and clean it when neces-
sary. Do not run the pump without a strainer.(See
previous notes.)
STOPPING
Never halt the flow of liquid suddenly.
Reduce the throttle speed slowly and allow the
engine to idle briefly before stopping.
COLD WEATHER PRESERVATION
Drain the pump to prevent freezing damage.
Clean out any solid by flushing with a hose.

Always check oil before starting use.
