Your semi-trash pump requires some assembly. This unit

ships from our factory without oil. It must be properly

serviced with fuel and oil before operation.

If you have any questions regarding the assembly of your

semi-trash pump, call our help line at 1-877-338-0999.

Please have your serial number and model number

available.

Remove the Semi-Trash Pump from the Shipping Carton

1. Set the shipping carton on a solid, flat surface.

2. Remove everything from the carton except the

semi-trash pump.

3. Carefully cut each corner of the box from top to bottom.

Remove Shipping Support Brackets

To protect the generator during shipping, support

brackets have been installed between the engine and

frame. These brackets MUST BE REMOVED BEFORE

adding oil or gasoline to the generator.

NOTE

DO NOT attempt to run generator without first
removing the shipping support brackets. Damage
to the generator as a result of not removing the
brackets will void the warranty.

Install the Vibration Mounts

1. Thread the flange bolt (M8x20) through the

vibration mount and then through the frame.

2. Firmly secure the bolt to the frame with the M8 nut.

Tighten. DO NOT over tighten.

3. Repeat steps 1-2 for the remaining mount (4 total).

Add Engine Oil

CAUTION

DO NOT attempt to crank or start the engine before
it has been properly filled with the recommended
type and amount of oil. Damage to the
semi-trash pump as a result of failure to follow
these instructions will void your warranty.

1. BEFORE filling the engine with oil or gasoline, tip

the generator onto it’s recoil end. Tip onto the

flattened cardboard box the generator came in or

other protective surface so as to not scratch the

frame.

2. Remove the bolts from the orange support brackets.

Bolts and brackets can be discarded.

3. Tip the generator upright.

NOTE

The recommended oil type is 10W-30 automotive
oil.

1. Place the semi-trash pump on a flat, level surface.

2. Remove oil fill cap/dipstick to add oil.

3. Add up to 0.6 qt. (0.6 L) of oil (not included) and

replace oil fill cap/dipstick. DO NOT OVERFILL.

4. Check engine oil level daily and add as needed.

7

66525 ENGLISH

Add Engine Oil Cont’d. Add Fuel Cont’d.

ASSEMBLY

NOTE

Check oil often during the break-in period. Refer to the
Maintenance section for recommended service intervals.

CAUTION

The engine is equipped with a low oil shut-off and
will stop when the oil level in the crankcase falls
below the threshold level.

Add Fuel

1. Use clean, fresh, regular unleaded fuel with a

minimum octane rating of 87 and an ethanol content

of less than 10% by volume.

2. DO NOT mix oil with fuel.

3. Clean the area around the fuel cap.

4. Remove the fuel cap.

5. Slowly add fuel to the tank. DO NOT OVERFILL.

Fuel can expand after filling. A minimum of ¼

in. (6.4 mm) of space left in the tank is required

for fuel expansion, more than ¼ in. (6.4 mm) is

recommended. Fuel can be forced out of the tank as

a result of expansion if it is overfilled, and can affect

the stable running condition of the product. When

filling the tank, it is recommended to leave enough

space for the fuel to expand.

6. Screw on the fuel cap and wipe away any spilled fuel.

CAUTION

Use regular unleaded gasoline with a minimum
octane rating of 87.

Do not mix oil and gasoline.
Fill tank to approximately ¼ in. (6.4 mm) below the
top of the tank to allow for fuel expansion.
DO NOT pump gas directly into the generator at the
gas station. Use an approved container to transfer
the fuel to the generator.
DO NOT fill fuel tank indoors.
DO NOT fill fuel tank when the engine is running or hot.
DO NOT overfill the fuel tank.
DO NOT light cigarettes or smoke when filling the
fuel tank.

NOTE

Our engines work well with 10% or less ethanol blend
fuels. When using blended fuels there are some issues
worth noting:

– Ethanol-gasoline blends can absorb more water than

gasoline alone.

– These blends can eventually separate, leaving water or

a watery goo in the tank, fuel valve and carburetor.

– With gravity-fed fuel supplies, this compromised fuel

can be drawn into the carburetor and cause damage to
the engine and/or potential hazards.

– There are only a few suppliers of fuel stabilizer that are

formulated to work with ethanol blend fuels.

– Any damages or hazards caused by using improper

fuel, improperly stored fuel, and/or improperly
formulated stabilizers, are not covered by

manufacture’s warranty.
It is advisable to always shut off the fuel supply, run the
engine to fuel starvation and drain the tank when the
equipment is not in use for more than 30 days.

WARNING

Pouring fuel too fast through the fuel screen may
result in blow back of fuel at the operator while filling.

Connecting Hose or Pipes

Hoses or pipes can be connected to the pump using

3 in. (7.6 cm) NPT pipe fittings.

Teflon tape is required to ensure a liquid tight seal.

Do not connect rigid pipe directly to the pump as this

can cause excess stress that can damage the pump.

Always use at least 12 in. (30.5 cm) of flexible hose

between the pump and any rigid piping.

ENGLISH 66525

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.

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.

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.

WARNING

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.

NOTE

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

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.

OPERATION

Starting the Engine Cont’d.

NOTE

Pump performance can be adjusted using the
throttle. To decrease pump output, slide the throttle
to the right. To increase it, slide the throttle to the
left.

WARNING

DO NOT remove either top, or drain (bottom) plugs
while the semi-trash pump is on and running

Loss of pressure and suction will occur. Injury may
also occur.

Stopping the Engine

1. Turn the fuel valve to the “OFF” position.

2. Let the engine run until fuel starvation has stopped

the engine. This usually takes a few minutes.

3. Move the throttle lever to slow position.

4. Press the engine switch to the “OFF” position.

Important: Always ensure that the Fuel Valve and the

Engine Switch are in the “OFF” position when the engine

is not in use.

NOTE

If the engine will not be used for a period of two (2)
weeks or longer, please see the Storage section for
proper engine and fuel storage.

Operation at High Altitude

The density of air at high altitudes is lower than at sea

level. Engine power is reduced as the air mass and air-

fuel ratio decrease. Engine power and semi-trash pump

output will be reduced approximately 3½% for every

1000 ft. of elevation above sea level. At high altitudes

increased exhaust emissions can also result due to the

increased enrichment of the air fuel ratio. Other high

altitude issues can include hard starting, increased fuel

consumption and spark plug fouling.

To alleviate high altitude issues other than the natural

power loss, CPE can provide a high altitude carburetor

main jet. The alternative main jet and installation

instructions can be obtained by contacting our

Technical Support Team. Installation instructions are

also available in the Technical Bulletin area of the CPE

website.

WARNING

Operation using the alternative main jet at
elevations lower than the recommended minimum
altitude can damage the engine. For operation at
lower elevations, the originally supplied standard
main jet must be used. Operating the engine with
the wrong engine configuration at a given altitude
may increase its emissions and decrease fuel
efficiency and performance.
