IMPORTANT

For best possible performance and continuous, satis­factory operation, read these instructions before in­stalling your new pump. Should service be required, this

manual can be a valuable guide, it should be kept near the
installation for ready reference.

INSTALLATION

LOCATION

Place unit as close to water source as possible to minimize
suction lift, obtain the best pumping performance, and aid in
priming. A typical portable installation is shown in Figure 1.

For permanent installation, mount unit on a foundation that
will support the weight of pump and engine and also provide
stability while the pump is running. For most permanent
installations, it is advisable to bolt unit directly to foundation.

NOTICE: 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.

SUCTION CONNECTION

Connect either rigid pipe or flexible suction hose to pump
suction as shown in Figure 1. If hose is selected, hose must
be rated to hold the suction pressure and prevent collapse
while the pump is running.

Make the suction line 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.

NOTICE: 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.

NOTICE: Use a suction screen to keep debris out of pump.

DISCHARGE CONNECTIONS

Your pump is equipped with a single port discharge. Select
the appropriate size for the application. Install a “T” as
shown to allow priming the pump without disconnecting the
piping.

OPERATION

NOTICE: Do not start or run pump dry or damage to the
mechanical seal will result.

NOTICE: Add engine oil before startup. Refer to the
engine operation manual before startup.

PRIMING THE PUMP

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, reprime 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.

Hazardous Suction.

Can trap persons
against suction inlet.

Always use strainer
on suction hose to
prevent entrapment.

Use pipe or reinforced hose to make
suction connection.
Hose must be strong enough to
not collapse during operation.

Suction screen area must be at least four
times suction pipe area.

All suction piping must slope up toward the
pump inlet.

Support the piping and fittings to reduce strain
on the pump case.

Priming Plug

Provide rigid
platform for pump.

flow rate exceeds pressure rating of pump Reduce system pressure requirement. Increase pressure capability of pump.
L. Obstruction in suction piping Locate and remove obstruction. Attach strainer.
M. Suction lift too high Check with gauge or measure vertical distance between water surface and

center line of pump, allowing for friction loss in suction pipe. Reduce rate of

flow to obtain desired lift. Refer to pump performance chart.
N. Discharge head too low Decrease rate of flow
O. Suction inlet not immersed deep enough Refer to “Installation”
P. Leaky suction line or connection admitting air Repair or replace suction line. Tighten connections.

Engine Safety Precautions:

Fire and explosion hazard. Gasoline can

explode. Store gasoline away from the engine. Add gasoline
to the engine only when the engine is off.

Burn hazard. Hot surface.The engine gets

very hot during operation. Do not touch the engine surfaces.
Keep children away. Allow the engine to cool before moving
it indoors.

Deadly fumes. Carbon monoxide. Never run

the engine in an enclosed space. Only use outdoors with
plenty of ventilation.

Engine Operation

Before starting the engine:

Check and Fill Oil

The engine is shipped without oil. It must be filled before
starting the engine.

Fill oil by removing the fill cap / dipstick. Add oil until the
level reaches the bottom of the opening. Check the oil level
by pushing the cleaned dipstick into the oil fill opening. DO
NOT SCREW IT IN. Remove the dipstick and inspect it. Add
oil if needed. Reinstall the cap / dipstick.

Oil capacity is 0.63 quarts (0.6 liter). 10W-30 oil should be
used in normal conditions. Use 10W-40 oil if the engine is to
be run in temperatures over 90°F (32°C) .

Note that the engine has a low-oil monitoring system. If the
oil level drops too low, the system will automatically turn off
the engine.

Add Gasoline

Fill gas tank with clean fresh gasoline. This should be
unleaded fuel that has an octane rating of 86 or higher.

Do not fill the tank to overflowing. Clean up any spilled gaso­line before starting the engine.

Open Fuel Valve

Move the fuel valve to the right to allow fuel to the engine.

Close Choke

When starting a cold engine, move the choke control to the
left (closed). As the engine warms up move it towards the
right (open). A warm engine should start with the choke
open.

Position Throttle

Move the throttle (speed control) slightly to the left.

Turn Engine Switch On

The engine switch controls the ignition. turn it to the ON
position to start the engine. The same control is used to stop
the engine.

Pull Starter

Pull the handle on the recoil starter. Adjust throttle to desired
speed. Move the choke to the right as engine warms.

Stopping the Engine

Stop the engine by turning the engine switch to OFF.
Turn the fuel control to OFF (left).

Engine Maintenance

Air filter

The air filter should be checked every month for dust and
dirt accumulation. Every 6 months the filter element should
be removed and cleaned. Clean the foam element with
detergent and warm water. Squeeze out excess water and
let it dry. Before reinstalling the filter element, soak it with
engine oil, and squeeze out the excess. Reinstall the filter.
The engine will smoke upon startup if too much oil is left in
the filter element.

Oil level

The oil level should be checked before each use.

Oil Change

The oil should be changed in the first month, and then every
6 months (or 100 hours of operation). To drain the oil, run
the engine until warm. Turn off the engine, remove the oil
drain plug, and let the the oil drain into a pan. Reinstall the
plug and fill with oil.

NOTE: Dispose of used oil responsibly. DO NOT pour it
down drains, onto the ground or put it in the trash. Most
communities have collection points for used oil.

Spark Plug

The spark plug should be checked and cleaned every 6
months or 100 hours.

The sparkplug should be replaced if it is damaged, or exces­sively worn.

The sparkplug is type BPR6ES (NGK) or equivalent. The
plug gap should be 0.030 in. (0.75 mm)

Engine Troubleshooting

If the engine won’t start:

• Check that there is gas in the tank

• Make sure the fuel valve is ON and that the engine switch
is ON

• Make sure there is enough oil in the engine to reset the
low-oil sensor

• Check that fuel is getting to the carburetor*

• Check for spark at the sparkplug*

* These checks to be done by persons with small-engine

experience.

Extended storage

If the pump will be stored for more than a month or two, fol­low the steps below.

• Drain Gasoline

• Change oil

• Squirt oil (or a chemical made for storing engines) in the
spark plug hole.

• Rotate engine slowly until resistance is felt (this indicates
that both valves are closed).

• Install spark plug

• Cover engine
