Operating Instructions

The pump is designed to pump water. Do not use it to pump flammable

liquids or chemicals.

Before starting the pump engine, prime the pump by removing the vent

plug and filling the pump casing with water. Do not run the pump dry as

damage can result. Fitting a foot valve (non-return valve) to the end of

the suction pipe, and filling the suction pipe with water will speed priming.

Fill the fuel tank with 2-stroke fuel, mixed at the ratio of 20:1 petrol to 2-

stroke oil (50ml of oil per litre of petrol).

WARNING!

Never fill the fuel tank whilst the engine is running. Always stop the

engine and allow to cool before filling with fuel.

Starting

1. Open the fuel cock.

2. Set the choke lever to position ‘C’.

3. Set the throttle lever to approximately 1/2 throttle.

4. Pull the starter recoil rope slowly two or three times to allow fuel to

reach the carburettor.

5. Hold the pump down and pull the starter recoil rope firmly until the

engine starts. Do not snatch at the starter rope, and allow the rope to

retract slowly after each pull.

6. Once the engine starts, return the choke lever to position ‘A’, and use

the throttle to gradually increase the engine revs to the desired speed.

Note: Do not run the pump at more than approximately 1/2 speed, or run

it for more than 3 hours continuously, for the first 20 to 30 hours of use. This

allows the pump to run-in.

Stopping

1. Gradually reduce the engine speed to minimum.

2. Stop the engine by pressing the Stop button, situated just above the

recoil unit at the back of the engine.

3. Close the fuel cock.

4. If the pump is not to be used for some time, or is in a location likely to

freeze, remove the drain plug and drain the pump completely.

If the pump has been used with dirty or salt water, rinse it through with

clean water.
