GENERAL SAFETY PRECAUTIONS

As with all machinery, there are certain hazards involved with its

operation and use. Exercising caution will reduce the risk of

personal injury.

WORK AREA

1. ALWAYS keep the work area clean and well lit. Floors should always be

kept clear. Cluttered or dark areas invite accidents.

2. ALWAYS keep children and bystanders away while operating machines.

Distractions can cause loss of control.

PERSONAL SAFETY

1. ALWAYS stay alert, watch what you are doing and use common sense

when operating this pump. Do not use the pump while you are tired or

under the influence of medication, drugs or alcohol. A moment of

inattention can result in personal injury.

2. ALWAYS wear suitable protective clothing and eye protection including

industrial gloves, ear defenders and approved impact resistant safety

glasses. (Eye glasses are NOT safety glasses)

3. NEVER over-reach. Keep your proper footing and balance at all times

when positioning or operating the pump.

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

5. ALWAYS dress properly. Never wear loose clothing or jewellery which could

be caught on moving parts.

6. ALWAYS store the pump out of reach of children and do not allow persons

unfamiliar with these instructions to operate this appliance.

7ALWAYS observe all safety precautions for the handling of fuel.

8. NEVER direct the discharge flow towards another person.

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

follow the instructions in this manual.

10. 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.

11. ALWAYS take care not to touch the exhaust pipe/ muffler when the pump

has been running and is hot. This assembly becomes hot enough to inflict

severe burns.

GENERAL EQUIPMENT USE AND CARE

1. ALWAYS maintain the pump with care and keep it clean for best / safest

performance.

2. NEVER use this pump if any part is damaged. Have it inspected and

repaired by your local Clarke dealer. Always turn the pump off before

carrying out any maintenance.

3. NEVER modify this pump in any way. Use it ONLY for the purpose for which

it is designed.

4. ALWAYS use at least 1ft (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.

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

sufficiently before refuelling.

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

chemicals. These pumps are designed to pump WATER ONLY.

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

combustible materials, or where there is insufficient ventilation.

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

9. ALWAYS keep the pump engine dry and well clear of water discharge.

10. NEVER overtighten drain or filler plugs. Excessive force may damage the

threads and make the plug difficult to remove in future.

11. ALWAYS use the strainer connected to the suction (inlet) hose, to prevent

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

damage to the pump.

SERVICING

1. ALWAYS have the pump serviced by your local CLARKE dealer, using only

identical replacement parts. This will ensure the safety of the pump is

maintained. The use of non standard parts could be hazardous.

2. NEVER attempt any repairs yourself. If you have a problem with the

machine contact your local CLARKE dealer.

Your CLARKE water pump has been designed to give long and trouble free

service. If, however, having followed the instructions in this booklet carefully,

you encounter problems, take the unit to your local CLARKE dealer.

INTRODUCTION

The CU150 Pump consists of a petrol (gasoline) engine and water pump

which is fixed to the frame via a shock absorbing mounting.

The self-priming pump consists of a pump body, cover, impeller and

mechanical seal assembly. The inlet of the pump is higher than the inlet of the

impeller so that it can start operating when only the body of the pump is filled

with water. The inlet of the pump is fitted with a one-way valve to prevent

water syphoning back out of the pump and ensure the pump is always

primed for the next start-up.

The engine used is an air-cooled, 4-stroke OHV unit which is lightweight and

compact. It is designed to run on unleaded petrol, with a manual pull-cord

starter and simple carburettor.

The CU150 is designed only for pumping water, or water containing small

solids in suspension. It is fitted with an open impeller, therefore the suction

strainer supplied, must always be fitted to the suction hose to ensure that

debris cannot be drawn up, causing damage to the pump.

Upon receipt, unpack and lay out the components, checking against the

following list. Any damage or deficiency should be reported to your CLARKE

dealer immediately.

PREPARATION FOR USE

INSTALLING THE HANDLE

The handle must be bolted to the frame using two

M8 x 12 bolts (item 2 - pages 20/21). Bolt the handle

to the frame & tighten securely as shown in Fig 3.

ADDING OIL

Note: This pump is not supplied with engine oil. Use

any engine oil of SAE 10W-30 rating unless

operating the pump at very high or low ambient

temperatures.

1. Remove the filler plug/dipstick from either side of

the crankcase.

2. Fill the engine with oil until visible

inside the filler tube.

3. Insert the dipstick back into the

filler tube and check the level is

within the indicated range. If

correct, replace the dipstick/filler

cap.

Note: Never add oil to the engine

when the machine is running.

ADDING FUEL

1. Open the fuel cap and top up as

required with unleaded petrol. Do

not fill above the shoulder of the

fuel strainer located inside the fuel

tank as shown in Fig 5. Ensure the

fuel is clean.

2. Inspect this filter during

subsequent refuelling and remove

any contaminants which may

have accumulated. After

refuelling, tighten the fuel filler

cap securely.

Note: Never add fuel to the engine when the pump is running.

WARNING: WIPE UP ANY SPILT FUEL BEFORE RUNNING THE

PUMP. ALLOW THE ENGINE TO COOL BEFORE REFUELLING.

INSTALLATION

POSITIONING THE PUMP

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

possible.

2. 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

operation.

CONNECTING THE HOSES

1. Connect the suction and discharge hoses to the pump housing using the

hose coupling adaptors, hose clamps and O-rings supplied to achieve an

air-tight seal. There must be no damage to the hoses which must be well

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 inhibit priming, and reduce the

capacity of the pump.

2. Pay particular attention to the following:

a. Always ensure the O-ring is placed between the hose

adaptor and pump casting.

b. Always use a flexible hose at the pump body connection of at

least 1ft (300mm).

c. Keep all pipes/hoses as short and straight as possible and

avoid sharp bends.

d. Ensure there is adequate drainage for the discharged water.

e. Ensure machine is on level ground or base to avoid spilling fuel.

f. If a flexible hose must be laid across a roadway, protect it with

planking.

(Instantaneous shut off pressure, applied when a vehicle runs across an

unprotected hose, could cause “hydraulic shock”, which can damage the

pump and/or the hose).

3. If the discharge line runs vertically more than 30ft it is advisable to install a

check valve in the discharge line near the pump to stop destructive water

hammer when the pump is shut down. If a check valve is installed, it may

also be necessary to vent the top of the pump so that air can he expelled

during automatic re-priming. This air bleed may he accomplished by

providing a 1/4" line from the top of the pump back to the liquid source.

We will not assume any responsibility for damage to the pump if no check

valve is used in the discharge line.

REMEMBER: Contaminated water is water containing small solids in

suspension, do not pump slurry, sludge, sand, or mud.

CONNECTING THE STRAINER

1. Attach the suction strainer to the end of suction hose using the third hose

clamp (of the three supplied), to prevent stones etc, from being drawn

up, which could cause severe damage to the pump. Keep the strainer

clean. If it is likely to clog with dirt or debris, proceed by either:

a. Preparing a bed of stones on which to rest the strainer.

b. Tying the strainer so that it stays clear of the bottom of the pit, pond

or excavation.

c. Tie the strainer inside a basket or bucket.

PRIMING THE PUMP

1. Remove the filler plug on top of the pump case and prime the pump with

water, leaving no air gap. Remember the pump is self-priming only when

filled. It will prime and re-prime itself without refilling. Refilling is necessary

only if the pump has been drained or if the water has been lost. Never

allow the pump to run dry.

OPERATION

WARNING: WHEN THE ENGINE IS RUNNING, THE EXHAUST PIPE &

MUFFLER ARE VERY HOT, TAKE CARE TO AVOID BURNS.

WARNING: NEVER RUN THE ENGINE IN AN ENCLOSED SPACE - ENSURE

THERE IS ADEQUATE VENTILATION.

1. Pull the starter recoil rope

slowly two or three times to

allow fuel to reach the

carburettor.

2. To start a cold engine, set

the choke level to the right

(CHOKE) position, but if the

engine is already warm, the

choke should be in the RUN

position.

3. Set the throttle about one

third OPEN (to the right).

4. Switch the engine ON/OFF rocker switch ON.

5. Pull the recoil starter rope firmly but without snatching and allow

it to retract slowly after each pull. Repeat until the engine starts.
