IMPORTANT SAFETY INSTRUCTIONS

Fuel Safety

 DANGER

GASOLINE AND GASOLINE VAPORS ARE HIGHLY
FLAMMABLE AND EXPLOSIVE.

Fire or explosion can cause severe burns or death.

Gasoline and gasoline vapors:

– Gasoline is highly flammable and explosive.

– Gasoline can cause a fire or explosion if ignited.

– Gasoline is a liquid fuel but its vapors can ignite.

– Gasoline is a skin irritant and needs to be cleaned up

immediately if spilled on skin or clothes.

– Gasoline has a distinctive odor, this will help detect potential

leaks quickly.

– In any petroleum gas fire, flames should not be extinguished

unless by doing so the fuel supply valve can be turned OFF.
This is because if a fire is extinguished and a supply of fuel is
not turned OFF, then an explosion hazard could be created.

When transporting or servicing the water pump:

Make certain that the fuel valve is in the OFF position, the gasoline
tank is empty.

Disconnect the spark plug wire.

When storing the water pump:

Store away from sparks, open flames, pilot lights, heat and other
sources of ignition.

Do not store water pump or gasoline near furnaces, water heaters,
or any other appliances that produce heat or have automatic
ignitions.

 WARNING

NEVER use a gasoline container, gasoline tank, or any other
fuel item that is broken, cut, torn or damaged.

– Gasoline expands or contracts with ambient temperatures.

Never fill the gasoline tank to full capacity, as gasoline needs
room to expand if temperatures rise.

When adding or removing gasoline:

DO NOT light or smoke cigarettes.

Turn the engine off and let it cool for at least two minutes before
removing the gasoline cap. Loosen the cap slowly to relieve
pressure in the tank.

Only fill or drain gasoline outdoors in a well-ventilated area.

DO NOT pump gasoline directly into the engine at the gas station.
Use an approved container to transfer the fuel to the engine.

DO NOT overfill the gasoline tank.

Always keep gasoline away from sparks, open flames, pilot lights,
heat and other sources of ignition.

When starting the engine:

DO NOT attempt to start a damaged engine.

Make certain that the gasoline cap, air filter, spark plug, fuel lines
and exhaust system are properly in place.

Allow spilled gasoline to evaporate fully before attempting to start
the engine.

Make certain that the water pump is resting firmly on level ground.

When operating the water pump:

DO NOT move or tip the water pump during operation.

DO NOT tip the water pump or allow fuel or oil to spill.

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 water pump as a result of failing to follow these
instructions will void your warranty.



NOTICE

The engine rotor has a sealed, pre-lubricated ball bearing that
requires no additional lubrication for the life of the bearing.



NOTICE

The recommended oil type for typical use is 10W-30
automotive oil. However, using the listed conventional oils

shown in the “Recommended Engine Oil Type” chart may be
used for typical use including the first 5 hours of the break-in
run time period of the engine.

If running water pump in extreme temperatures, refer to the
“Recommended Engine Oil Type” chart.

 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.



NOTICE

The first 5 hours of run time is the break-in period for the
engine. During the break in period, it is recommended to use
standard automotive, non-synthetic blended oils. After the
break-in period, synthetic oil can be used but is not required.

Adjusting throttle setting will increase/ decrease engine speed
helping to seat piston rings. Avoid bogging or lugging the
engine down and avoid prolonged running at constant RPM.
After the 5-hour break-in period, change the oil.



NOTICE

Add Fuel

 DANGER

Gasoline vapors are highly flammable and extremely explosive.

DO NOT light or smoke cigarettes. Fire or explosion can cause
severe burns or death.

Only fill or drain fuel outdoors in a well-ventilated area. DO
NOT pump gasoline directly into the engine. Use an approved
container to transfer the fuel to the engine.

Never use a gasoline container, gasoline tank, or any other fuel
item that is broken, cut, torn or damaged.

DO NOT overfill the gasoline tank. Always keep fuel away from
sparks, open flames, pilot lights, heat and other sources of
ignition.

Use clean, fresh, regular unleaded gasoline with a minimum
octane rating of 87 and an ethanol content of less than 10% by
volume. ybc

DO NOT mix oil with gasoline.

 CAUTION

Use regular unleaded gasoline with a minimum octane rating
of 87 and an ethanol content of less than 10% by volume.

DO NOT light cigarettes or smoke when filling the tank.

DO NOT mix oil and gasoline.

Fill tank to approximately ¼ in. (6.4 mm) below the top of the
tank to allow for gasoline expansion.

DO NOT pump gasoline directly into the water pump at the
pump. Use an approved container to transfer the gasoline to
the water pump.

DO NOT fill tank indoors.

DO NOT fill tank when the engine is running or hot.

DO NOT overfill the tank.

 WARNING

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

1. Place the water pump on a flat, level surface.

2. Remove the gasoline cap.

3. Slowly add gasoline to the tank. DO NOT OVERFILL. Gasoline
can expand after filling. A minimum of ¼ in. (6.4 mm) of
space left in the tank is required for gasoline expansion,
although more than ¼ in. (6.4 mm) is recommended. Gasoline
can be forced out of the tank as a result of expansion if
overfilled, and can affect the stable running condition of the
water pump.

4. Screw on the gasoline cap and wipe away any spilled fuel.



NOTICE

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

– Ethanol-gasoline blends can absorb more water than

gasoline alone.

– These ethanol blends can eventually separate, leaving

water or a watery goo in the tank, fuel valve and
carburetor. The compromised gasoline can be drawn into
the carburetor and cause damage to the engine and/or
create potential hazards.

– If a fuel stabilizer is used, confirm that it is formulated to

work with ethanol-gasoline blends.

– Any damages or hazards caused by using ethanol blended

gasoline higher than 10% by volume, improperly stored
gasoline, and/or improperly formulated stabilizers, are not
covered by manufacturer’s warranty.

It is advisable to always shut off the gasoline supply and
run the engine to starvation after each use. See Storage
instructions for extended non-use.

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 semi­trash 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.

A

B

C

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.

2. Thread the assembled connector to the outlet fitting (top of
pump).



NOTICE

Make sure the gasket is seated inside before threading the
adapter on.

Priming the Pump



NOTICE

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.

Located on the outlet flange is the priming plug. Remove the
priming plug and fill pump body to the very top of outlet flange
with water. Reinstall the priming plug. As the engine starts up,
this will start the draw of liquid into the pump. Located within
the pump assembly is the one-way valve. As you prime the pump
housing this one-way flap valve shuts off the opening to the
suction hose. The priming process is only required when the pump
housing is not full of water.

22. You should have everything connected.



NOTICE

Ensure the priming plug is secure before pump operation, if not
secure the priming plug could be ejected and water or other
liquids could be pumped through the top of the outlet flange.



NOTICE

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.

B

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.



NOTICE

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 altitude is lower than at sea level.

A

Engine power is reduced as the air mass and air-fuel ratio
decrease. Engine power and water pump output will be reduced
approximately 3½% for every 1000 ft. of elevation above sea
level. This is a natural trend and cannot be changed by adjusting
the engine. 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.



NOTICE

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.



NOTICE

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.

The part number and recommended minimum altitude for the
application of the high altitude carburetor main jet is listed in the
table below.

In order to select the correct high altitude main jet it is necessary
to identify the carburetor model. For this purpose, a code is
stamped on the side of the carburetor. Select the correct high
altitude jet part number corresponding to the carburetor code
found on your particular carburetor.

CHAMPION POWER EQUIPMENT, INC. (CPE)

AND THE UNITED STATES ENVIRONMENT PROTECTION AGENCY (U.S. EPA)

EMISSION CONTROL SYSTEM WARRANTY

Your Champion Power Equipment (CPE) engine complies with U.S. EPA emission regulations.

YOUR WARRANTY RIGHTS AND OBLIGATIONS:

The US EPA AND CPE are pleased to explain the Federal Emission Control Systems Warranty on your 2023 small off-road engine (SORE)
and engine powered equipment. New engines and equipment must be designed, built and equipped, at the time of sale, to meet U.S.
EPA regulations for small off-road engines (SORE). CPE warrants the emission control system on your small off-road engine (SORE)
and equipment for the period of time listed below, provided there has been no abuse, neglect, unapproved modification, or improper
maintenance of your equipment.

Your emission control system may include parts such as the carburetor, fuel-injection system, the ignition system, catalytic converter and
fuel lines. Also included may be hoses, belts, connectors and other emission related assemblies. Where a warrantable condition exits, CPE
will repair your small off-road engine (SORE) at no cost to you including diagnosis, parts and labor.

MANUFACTURER’S EMISSION CONTROL SYSTEM WARRANTY COVERAGE:

This emission control system is warranted for two years, subject to provisions set forth below. If, during the warranty period, an emission
related part on your engine is defective in materials or workmanship, the part will be repaired or replaced by CPE.

OWNER WARRANTY RESPONSIBILITIES:

As the small off-road engine (SORE) owner, you are responsible for the performance of the required maintenance listed in your Owner’s
Manual. CPE recommends that you retain all your receipts covering maintenance on your small off-road engine (SORE), but CPE cannot
deny warranty solely for the lack of receipts or for your failure to ensure the performance of all scheduled maintenance.

As the small off-road engine (SORE) owner, you should however be aware that CPE may deny you warranty coverage if your small, off-road
engine (SORE) or a part has failed due to abuse, neglect, improper maintenance or unapproved modifications.

You are responsible for presenting your small off-road engine (SORE) to an Authorized CPE service outlet or alternate service outlet as
described in (3)(f.) below, CPE dealer or CPE, Santa Fe Springs, Ca. as soon as a problem exists. The warranty repairs should be completed
in a reasonable amount of time, not to exceed 30 days.

If you have any questions regarding your warranty rights and responsibilities, you should contact:

EMISSION CONTROL SYSTEM WARRANTY

The following are specific provisions relative to your Emission Control System (ECS) Warranty Coverage.

1. APPLICABILITY: This warranty shall apply to 1997 and later model year small off-road engines (SORE). The ECS Warranty Period shall

begin on the date the new engine or equipment is delivered to its original, end-use purchaser, and shall continue for 24 consecutive
months thereafter.

2. GENERAL EMISSIONS WARRANTY COVERAGE
CPE warrants to the original, end-use purchaser of the new engine or equipment and to each subsequent purchaser that each of its
small off-road engines (SORE) is:

2a. Designed, built and equipped so as to conform to U.S. EPA emissions standards for spark-ignited engines at or below 19 kilowatts.

2b. Free from defects in materials and workmanship that cause the failure of a warranted part to be identical in all material respects

to the part as described in the engine manufacturer’s application for certification for a period of two years.

3. THE WARRANTY ON EMISSION-RELATED PARTS WILL BE INTERPRETED AS FOLLOWS:

3a. Any warranted part that is not scheduled for replacement as required maintenance in the Owners Manual shall be warranted for

the ECS Warranty Period. If any such part fails during the ECS Warranty Period, it shall be repaired or replaced by CPE according
to Subsection “d” below. Any such part repaired or replaced under the ECS Warranty shall be warranted for any remainder of the
ECS Warranty Period.

3b. Any warranted, emissions-related part which is scheduled only for regular inspection as specified in the Owners Manual shall be

warranted for the ECS Warranty Period. A statement in such written instructions to the effect of “repair or replace as necessary”,
shall not reduce the ECS Warranty Period. Any such part repaired or replaced under the ECS Warranty shall be warranted for the
remainder of the ECS Warranty Period.

3c. Any warranted, emissions-related part which is scheduled for replacement as required maintenance in the Owner’s Manual shall

be warranted for the period of time prior to the first scheduled replacement point for that part. If the part fails prior to the first
scheduled replacement, the part shall be repaired or replaced by CPE according to Subsection “d” below. Any such emissions­related part repaired or replaced under the ECS Warranty, shall be warranted for the remainder of the ECS Warranty Period prior to
the first scheduled replacement point for such emissions-related part.

3d. Repair or replacement of any warranted, emissions-related part under this ECS Warranty shall be performed at no charge to the

owner at a CPE Authorized Service Outlet.

3e. The owner shall not be charged for diagnostic labor which leads to the determination that a part covered by the ECS Warranty is in

fact defective, provided that such diagnostic work is performed at a CPE Authorized Service Outlet.

3f. CPE shall pay for covered emissions warranty repairs at non-authorized service outlets under the following circumstances:

i. The service is required in a population center with a population over 100,000 according to U.S. Census 2000 without a CPE

Authorized Service Outlet AND

ii. The service is required more than 100 miles from a CPE Authorized Service Outlet. The 100 mile limitation does not apply in the

following states: Alaska, Arizona, Colorado, Hawaii, Idaho, Montana, Nebraska, Nevada, New Mexico, Oregon, Texas, Utah and
Wyoming.

3g. CPE shall be liable for damages to other original engine components or approved modifications proximately caused by a failure

under warranty of an emission-related part covered by the ECS Warranty.

3h. Throughout the ECS Warranty Period, CPE shall maintain a supply of warranted emission-related parts sufficient to meet the

expected demand for such emission-related parts.

3i. Any CPE Authorized and approved emission-related replacement part may be used in the performance of any ECS Warranty

maintenance or repair and will be provided without charge to the owner. Such use shall not reduce CPE’s warranty obligation.

3j. Unapproved add-on or modified parts may not be used to modify or repair a CPE engine. Such use voids this ECS Warranty and

shall be sufficient grounds for disallowing an ECS Warranty claim. CPE shall not be liable hereunder for failures of any warranted
parts of a CPE engine caused by the use of such an unapproved add-on or modified part.

sell and service that CPE product during his normal business hours. Alternate service locations defined in Section (3)(f.) above must be
