GENERAL SAFETY RULES

1. ALWAYS observe all safety precautions for the handling of fuel.

2. ALWAYS thoroughly familiarise yourself with this pump & its operation, and

follow all instructions in this manual.

3. ALWAYS ensure that the pump is properly positioned where necessary to

prevent it from moving during operation, and that the immediate area

surrounding the pump is kept clear.

4. ALWAYS use the strainer connected to the suction hose to prevent stones

and other solids from being drawn up, which could cause severe damage

to the pump.

5. ALWAYS keep the pump itself dry and well clear of water discharge.

6. ALWAYS use only replacement parts supplied by the manufacturer. The use

of non-standard parts could be hazardous.

7. ALWAYS use at least 300mm of flexible hose to make plumbing connections

to the pump. Rigid piping may put stress on the pump, causing damage. If

rigid piping must be used, it should be supported so as to eliminate stress on

the pump.

8. NEVER refuel the engine whilst it is running and allow the engine to cool

sufficiently before refuelling.

9. NEVER use for pumping petrol (or other flammable liquids), or corrosive

chemicals. This pump is designed to pump WATER ONLY.

10. NEVER operate an engine driven pump in an explosive atmosphere, near

combustible materials, or where there is insufficient ventilation.

11. NEVER allow children to use this pump.

12. NEVER run the pump dry. Always fill the pump with water before starting.

13. NEVER direct the discharge flow towards another person.

14. NEVER over-tighten drain or filler plugs. Excessive force may damage the

threads or the pump body.

15. NEVER direct the water discharge towards electrical wiring or equipment.

WARNING: WHEN USING POWERED PRODUCTS, BASIC SAFETY

PRECAUTIONS SHOULD ALWAYS BE FOLLOWED TO REDUCE THE RISK OF

FIRE, ELECTRIC SHOCK AND PERSONAL INJURY. READ ALL THESE

INSTRUCTIONS BEFORE ATTEMPTING TO OPERATE THIS PRODUCT AND

INVENTORY

The items above should be supplied in the carton. If any items are missing or

damaged, please contact the Clarke dealer where you purchased the

product.

BEFORE USE

FITTING THE FEET

1. Fit the 4 x rubber feet to the frame

using the nuts and washers

supplied.

FILLING WITH OIL

This pump is not supplied containing

engine oil or fuel. Use any engine oil

of SAE 10-30 rating unless operating

at very high or low ambient

temperatures.

To fill the engine crankcase with oil:

1. Remove the filler plug/dipstick.

2. Fill the unit with oil until visible

inside.

3. Check the level by inserting the

dipstick back into the filler tube

and checking the level is within

the indicated range. If correct

replace the dipstick/filler cap.

FILLING WITH FUEL (ONLY USE REGULAR UNLEADED PETROL)

Fill the fuel tank with unleaded petrol

or check the level by opening the

fuel cap and topping up as required.

Located within the fuel tank is a

strainer. Check this filter periodically

and remove any contaminants

which may have accumulated. Do

not fill above the fuel strainer

shoulder.

After refuelling, tighten the fuel filler

cap securely.

WARNING: WIPE UP ANY SPILT FUEL BEFORE RUNNING THE PUMP.

ALLOW THE ENGINE TO COOL DOWN BEFORE REFUELLING

INSTALLING THE PUMP

1. Position the pump on a firm foundation and as near to the water source as

possible.

2. Connect the suction and

discharge hoses to the pump

using the hose clamps and sealing

rings supplied, to achieve an

airtight seal.

• There must be no damage to

the hoses which must be

adequately protected and

supported.

NOTE: Hoses or pipes should be

supported independently

and not carried by the

pump.

IMPORTANT: An air leak in the suction

line will prevent priming, and reduce

the performance of the pump.

3. Pay particular attention to the

following:

• Always ensure the hose adaptor sealing ring is in place and correctly

fitted.

• Always use a flexible hose at the pump body connection of at least

1ft (300 mm) length.

• Keep all pipes/hoses as short and straight as possible and avoid

sharp bends. If a flexible hose must be laid across a roadway,

protect it with planking.

• Ensure there is adequate drainage for the discharged water, and

that there is no danger of damage to property as a result of the

pumping activity..

NOTE: Instantaneous shut off pressure, applied when a vehicle runs

across an unprotected hose, will cause “hydraulic shock”, which

can damage the pump and/or the hose.

Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com

4. Attach the inlet strainer to the end

of suction hose using a further

hose clamp, to prevent large

stones etc, from being drawn up

which could cause severe

damage. Keep the strainer free of

debris.

5. If it is likely to clog with dirt or

debris, proceed by either:

• preparing a bed of stones on

which to rest the strainer.

• tying the strainer so that it stays off the bottom of the pit, pond or

excavation.

• rest the strainer inside a basket or bucket to keep undue debris

away.

6. Prime the pump with water by

removing the filler plug on top of

the pump and filling with water,

leaving no air gap.

• The pump is self-priming only

when the pump is filled. It will

prime and re-prime itself

without refilling. Refilling is

necessary only if the pump has

been drained.

7. Never allow the pump to run dry.

8. If the discharge hose runs

vertically more than 30ft a check

valve should be installed in the

discharge hose near the pump to

stop water hammer when the

pump is shut down.

• It is the pump owners

responsibility to supply and

instal a check valve to protect

the pump in this way.

9. Properly fuelled and lubricated, the pump will run without further attention.

OPERATION

Ensure the site and pump are prepared, then proceed as follows:

STARTING

• Note the markings displayed on the engine parts, for the following

settings.

1. Set the engine On/Off switch to

On.

2. Move the fuel valve to the right

side (open position).

3. Pull the starter recoil rope slowly

two or three times to allow fuel to

reach the carburetor.

• The direction of operation is

marked on the machine.

4. To start a cold engine, set the

choke lever to the left (closed

position), but if the engine is

already warm, the choke should

be in the open position to the

right.

5. Set the throttle about one third

open. Set the engine switch ON.

6. Pull the starter recoil rope firmly

until the engine starts. Do not

snatch at the starter rope and allow it to recoil slowly after each pull.

7. Once the engine starts, gradually return the choke to the open position as

the engine warms up and use the engine throttle to gradually increase

engine speed.

PRIMING & CONTROL

After starting the engine, move the throttle to the open position for priming of

the pump and checking for pump output. Output is controlled by adjusting

the engine speed.

WARNING: WHEN THE ENGINE IS RUNNING THE EXHAUST MUFFLER

IS VERY HOT. TAKE CARE TO AVOID BURNS. NEVER RUN THE ENGINE

IN AN ENCLOSED SPACE - ENSURE THERE IS ADEQUATE

VENTILATION.

Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com

With a suction lift of 5 to 10ft, the pump should begin discharging liquid in a

few moments. To further reduce priming time, the engine speed may be

increased after the engine is properly run in. If pumping does not start within

this time, shut off engine and check carefully to find the problem. See

TROUBLESHOOTING.

NOTE: Filling the suction pipe with water will speed up the priming

process, and it is recommended that a non-return valve be fitted

to the end of the suction pipe.

On higher vertical lifts, a higher engine speed is necessary but on shallow lifts

or when there is little water to pump, preserve fuel and engine wear by

reducing engine speed.

In the event of blockages, where debris has entered the suction chamber, the

suction chamber can be opened and cleaned out by removing the bolts (12)

shown in the layout on page 18.

SHUTTING DOWN

1. Reduce engine speed to minimum using the throttle lever.

2. Stop the engine by switching OFF the ignition switch.

3. Close the fuel valve.

MAINTENANCE

1. Always maintain the pump in a clean condition, checking regularly for

loose bolts etc.

2. Clean the air filter once every 50 hours of use (or more often in unusually

dusty conditions) as follows.

3. Unscrew the wingnut and lift off the air filter assembly from the engine.

4. Remove the components shown

and clean the foam filter element

with a high flashpoint solvent.

Squeeze dry, then dip in clean

engine oil and squeeze oil excess

oil.

• Never operate the pump

without the air cleaner installed

as this would cause premature

wear to the engine.
