GENERAL SAFETY RULES

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

operation and use. Exercising caution will reduce the risk of

personal injury.

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

2. ALWAYS thoroughly familiarise yourself with this unit & 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 ensure the unit cannot be started inadvertently by using the ON/OFF switch

whenever carrying out maintenance or making adjustments.

5. 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.

6. ALWAYS keep the machine itself dry and well clear of water discharge

7. ALWAYS use only replacement parts supplied by the manufacturer. The use of non-standard

parts could be hazardous.

8. 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.

9. NEVER refuel the engine whilst it is running, and allow the engine to cool sufficiently before

refuelling.

10. NEVER use for pumping petrol (or other flammable liquids), or corrosive chemicals. These

pumps are designed to pump WATER ONLY.

11. NEVER operate an engine driven unit in an explosive atmosphere, near combustible

materials, or where there is insufficient ventilation.

12. NEVER allow children to use this machine.

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

14. NEVER attempt any major repairs to this machine unless you are properly qualified.

15. NEVER direct the discharge flow towards another person.

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

pump body.

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

OVERVIEW

These petrol driven pumps are designed for pumping water, or water containing small solids in

suspension. The pumps are fitted with an open impeller. The suction strainer supplied, must

always be used, to ensure that large stones or other objects cannot be drawn up, as this would

cause severe damage to the pump. The images show a PW3 pump although PW2 pumps are

similar.

BEFORE USE

REMEMBER: Contaminated water is water containing small solids in suspension, NOT

slurry, sludge, sand, or mud.

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

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.

ADDING OIL

This pump is not supplied with engine oil or

fuel. Use any engine oil of SAE 10-30 rating

unless operating at very high or low ambient

temperatures.

Fill the engine crankcase with oil as follows;

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.

NOTE: The unit is fitted with a low oil sensor which will stop the engine if the oil level drops

below the safe level to avoid internal damage. Refer to troubleshooting section.

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

ALLOW THE ENGINE TO COOL DOWN BEFORE REFUELLING

ADDING FUEL

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.

Use unleaded petrol with a pump octane rating

of 86 or higher.

GENERAL USE OF THE PUMP

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

gaskets supplied to achieve an airtight seal. There must be no damage of any kind 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 prevent priming, and reduce the capacity of the

pump.

2. Pay particular attention to the following:

a. Always ensure the hose adaptor gasket is in place, and correctly fitted.

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

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

(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).

3. Attach the suction 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

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 off the bottom of the pit, pond or excavation.

c. Tie the strainer inside a basket or bucket.

4. 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 the pump is 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.

5. 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.

Properly fuelled and lubricated your pump will run without attention.

OPERATION (REFER TO THE ILLUSTRATION ON PAGE 4)

WARNING: WHEN THE ENGINE IS RUNNING, THE EXHAUST MUFFLER IS

VERY HOT, TAKE CARE TOAVOID BURNS.

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

THERE IS ADEQUATE VENTILATION.

Ensure the site and pump is prepared as detailed on page 6, then proceed as follows:

PRIMING & CONTROL

1. With the fuel cock open, 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 lever to the closed position, but if the engine is already

warm, the choke should be in the open position.

3. Set the throttle about one third open. Turn the engine switch to ON.

4. Pull the starter recoil rope firmly until the engine starts. Do not snatch at the starter rope and

allow it to retract slowly after each pull.

5. 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.

STARTING

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.

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

minute. A lift of 25ft (at sea level) should require not more than 2 minutes for initial prime. 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 on page 9).

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 shown in the layout on page 4.

SHUTTING DOWN

1. Gradually reduce engine speed to minimum using the throttle lever.

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

3. Close the fuel cock.

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. Clean the foam filter element with domestic detergents and clean the mesh

element by knocking against a solid object or blow out any dust with a high pressure air jet.

Never operate the pump without the air cleaner installed as this would cause premature

wear to the engine.

3. Replace the spark plug after the first month or every 50 hours of use. Check when installing

that the spark plug has the correct clearance by measuring with a feeler gauge and adjusting

the side electrode as required. Clearance should be 0.70-0.80mm. The recommended spark

plug for both the PW2 and PW3 pump is RK34200/168F.

CHANGING THE OIL

The oil in the engine should be changed after the first 20 hours use and thereafter every 6

months or 100 running hours. Remove the dipstick and drain plug and then drain the oil. Re-fill

and check the level as described on page 5.

CAUTION: PROLONGED EXPOSURE TO USED OIL IS DANGEROUS, ALWAYS WASH YOUR

HANDS THOROUGHLY AFTER HANDLING USED OIL

ENVIRONMENTAL PROTECTION

One of the most damaging sources of pollution is oil. Do not throw away used oil with domestic

refuse or flush down a sink or drain. Collect old oil in a leak-proof container and take it to your

local waste disposal site.

STORAGE & HANDLING

After use, drain the pump body whenever there is danger of freezing, and if the pump has been

used with contaminated or salty water, It should be thoroughly flushed with clean water following

use, both inside and out and drained before replacing the drain plug. Always transport the pump

with the fuel cock turned off and keep the unit level to prevent any fuel from spilling.

If the pump is not to be used for some time, it should be flushed thoroughly with clean water, and

drained completely before storing in a clean dry environment. Additionally, it should be prepared

as follows:

1. Drain the fuel tank and carburettor completely by opening the drain plug in the carburettor

float chamber and draining all remaining fuel into a suitable container ensuring the fuel shut-

off valve is open.

2. Remove the spark plug, and pour 2-3 teaspoons of light oil into the cylinder through the

spark plug hole.

3. Pull the starter recoil rope slowly 2 or 3 times so that the oil is deposited on the cylinder

walls and replace the spark plug. For longer term storage, use the starter to turn the engine

until the triangle mark on the starter wheel lines up with the starter screw hole. In this

location both the inlet and exhaust valves are closed which may prevent the engine from

suffering internal corrosion during storage.
