INSTALLATION
These instructions are a guide only. Users not familiar with pumping
equipment should seek advice from people experienced in pump
equipment and installation.
Freezing conditions will damage the unit, because when water
freezes it expands. Ensure that the pump is located so that it is not
prone to freezing, or ensure that the product is disconnected and
dried of water during cold conditions.
Do not install or operate your pump in an explosive environment or
near combustible matter. Incorrectly installed or tested equipment
may fail, causing severe injury or property damage.
Fire and explosion hazard. Gasoline can explode. Store gasoline
away from engine. Add gasoline to the engine only when engine is
off and has cooled down.
Burn hazard. Hot suface. The engine gets very hot during operation.
Do not touch the engine surfaces. Keep children away. Allow engine
to cool before moving.
Deadly fumes. Carbon monoxide. Never run the engine in an enclosed
space. Only use outdoors with plenty of ventilation.
Site conditions. Only place and run the engine on stable flat ground.
Never run the engine on an incline, as this may cause the engine oil
to pool to one end of the sump and cause the low oil sensor to stop
the engine.
Priming the pump. Before starting the engine ensure the pump has
been filled with water. This can be achieved by removing the priming
plug from the pump casing and pouring water into the pump from
a container. Failure to prime the pump may result in damage to the
mechanical seal.

INSTALLATION
IMPORTANT
1. Preparation for installation
Inspect your pump for shipping damage. Report any damage to your Onga Dealer.
Place the pump as close as possible to the water source to minimise suction lift,
obtain best performance from the pump and aid in priming. A typical installation is
shown in figure 1 (page 8).
For permanent installation, mount the unit on a foundation that will support the weight
of the pump and engine and also provide stability while the pump is running. For most
permanent installations it is advisable to bolt the pump directly to the foundation.
2. Suction connection
Connect either rigid pipe or flexible suction hose to pump suction as shown in figure
1 (page 8). If hose is selected, hose must be rated to hold the suction pressure and
prevent collapse while the pump is running. Ensure the suction line has a continuous
rise from the water source to the pump. High spots can trap air and also make priming
difficult. Make sure all connections are tight and free of air leaks.
Note 1: Settling and/or shifting during operation can cause piping to place excessive
strain on the pump and may damage pump case. Set pump on hard level
surface.
Note 2: Suction pipe or hose must be at least as large as the pump suction inlet in
order for the pump to operate properly. Minimum depth for the suction inlet
is determined by the diameter of the suction line. See figure 1 (page 8).
Note 3: Use a suction screen to keep debris out of pump.
3. Discharge connection
Your pump is equipped with a single port discharge. Select the appropriate size for the
application. Install a “T” as shown in figure 1 (page 8), to allow priming of the pump
without disconnecting the piping.
Read the following instructions in this owner’s manual
when installing and operating equipment.

OPERATION
A self priming pump only needs to be manually primed at the first start up. Once
primed, under normal conditions the pump will reprime automatically at each
subsequent start up. If the pump is used in portable applications and the water has
been drained from the pump case, repriming will be required before start up.
To prime, remove plug from top discharge outlet and fill pump with water. Replace
plug and start pump. The pump will require a few minutes to evacuate air from
the suction line. After several minutes of operation, pump will be fully primed and
pumping water. Priming time will vary depending on length and diameter of suction
line.
Note 1: Do not start or run pump dry or damage to the mechanical seal will result.
Note 2: Add engine oil before start up. Refer to the engine operation manual before
start up.
Preparation before starting the pump
Fuel: Check fuel level in tank and do not over fill. Use fresh clean unleaded fuel.
Do not fill fuel tank when engine is running.
Oil: Before checking or refilling with engine oil, make sure the engine is stopped
and on a stable, level surface. Use oil recommended for ambient air
temperatures that the engine will be running at. See chart below. Change
engine oil after initial 5 hours running and at least every 20 hours thereafter.

Priming the pump
On self priming pumps, only the chamber needs to be filled with liquid. The pump
must not be run unless the chamber is completely filled with liquid because there
is a danger of damaging the mechanical seal, which depends on the liquid for its
lubrication.
Self priming pumps can be primed by removing the filler cap located on the top of
the pump where the discharge line is mounted to the pump and filling the priming
chamber with liquid. After use, the priming chamber should be flushed and drained
to avoid chemical corrosion and damage from freezing. Drain by removing the lower
drain plug located at the bottom of the casing.
Starting the pump
A. Turn engine switch located by recoil starter to ON position.
B. Turn the fuel cock to ON.
C. Push the throttle lever to a slightly open position.
D. Operation of the choke lever:
When engine is cold:
• In cold weather, start engine with choke in fully closed position.
• In warm weather, start engine with choke in half-closed position.
When engine is warm:
• Start engine with the choke in the fully open position
Start engine by pulling the recoil starter out quickly and forcefully.
Repeat pulling until engine starts.
Operation of the pump
A. Idle the engine for 3 to 5 minutes to warm it up.
B. Open the throttle lever to the upper zone after the engine has warmed up.
C. Once the engine has primed, you will note a load on the engine; adjust
RPM to proper speed for your pumping application.
OPERATION
IMPORTANT
IMPORTANT
Pump must not run dry.
Before starting the engine, ensure the priming chamber is filled
with liquid and the discharge hose is secure.
