Semi-Trash Pump location
Place the semi-trash pump in a well ventilated area. DO
NOT place the semi-trash pump near vents or intakes
where exhaust fumes could be drawn into occupied
or confined spaces. Carefully consider wind and air
currents when positioning semi-trash pump.
This semi-trash pump must have at least 5 ft. (1.5 m) of
clearance from combustible material. Leave at least
3 ft. (91.4 cm) of clearance on all sides of the semi-
trash pump to allow for adequate cooling, maintenance
and servicing.
Place the pump on a level surface free from any
obstructions or potential hazards. The pump should
be placed close to the water level to ensure maximum
pump performance.
Pump output will be affected by the type, length, and
size of the suction and discharge hoses. The pumping
height, also known as the total head, is the distance
from the water level to the point of discharge. As
this distance increases, pump output decreases. The
discharge capacity is greater than the suction capacity.
Therefore, it is important that the suction head is less
than the discharge head.
The time required to draw water from the source to
the pump (self-priming time) can be decreased by
minimizing the suction head.
OPERATION
If the engine starts but does not run make certain
that the semi-trash pump is on a flat, level surface.
The engine is equipped with a low oil sensor that
will prevent the engine from running when the oil
level falls below a critical threshold.
NOTE
DO NOT run the pump dry.
Running the pump dry can destroy the pump seals
and will void the warranty. If the pump was running
while dry, stop the engine and allow it to cool
thoroughly before filling the chamber with water.

Keep choke lever in “Choke” position for 2 pulls of
the recoil starter. After 2 pulls, move choke lever to
the “Run” position for up to the next 3 pulls of the
recoil starter. Too much choke leads to spark plug
fouling/engine flooding due to the lack of incoming
air. This will cause the engine not to start.

Priming the Pump
1. Remove the Pump Priming Plug (#15)
2. Completely fill the pump with liquid.
3. Replace the Pump Priming Plug
Starting the Engine
1. Make certain the semi-trash pump is on a flat, level
surface.
2. Flip engine switch (A) to “ON” position.
3. Rotate the fuel valve (B) to the “ON” position.
4. Move the choke lever (C) to the “Choke” position.
5. Move throttle lever to middle position. (D)
6. Pull the starter cord slowly until resistance is felt
and then pull rapidly.
7. As engine warms up, move the choke lever (C) to “Run”.
8. Move the throttle lever (D) to the “Fast” position.
