IV. GETTING STARTED

4.1- Unpacking

• Remove product from its packaging.
• Check that product and accessories are not damage
• Place the pump on a flat, firm surface.

4.2- Carrying handle

Insert and screw the carrying handle (2) in its location (see fig.1)

4.3- Hoses assembly

Important: Hoses are not included

Use only PVC suction ringed hoses or other hoses with similar quality.

4.3.1- Suction hose

a) Preliminary notes:

Use a commercially available hose, hose connector, and hose clamp.

The suction hose must be of reinforced, non-collapsible wall or wire braided hose to prevent suction collapse.

The suction hose length should not be longer than necessary, as the pump performance is best when the pump is not far above the water level.

Self-priming time is also proportional to the suction hose length.

Using a longer suction hose will increase the self-priming time.

The strainer is provided with the pump and should be attached to the end of the suction hose with a clamp as shown (fig.6)

b) Assembly (Fig.6)

1. Insert the coupling into the suction hose.
2. Use the clamps and tape (not supplied) and tighten firmly. Then screw the hose coupling to the pump suction inlet [11].
3. Insert strainer in suction hose.
4. Use the clamps and tape (not supplied) and tighten firmly Remark: always install the strainer on the end of the suction hose before pumping. The strainer will prevent debris from entering the pump that can cause slogging or pump damage.

Fig.6

Note: Make sure the washer is properly fitted on the intake hose coupling.

If the washer of the suction hose is loosened, or the hose buckle is lost or damaged, the water will not be pumped properly due to air leakage

4.3.2- Discharge hose

a) Preliminary notes:

Use a commercially available hose, hose connector, and hose clamp. A short, large-diameter hose is most efficient.

A long or small-diameter hose increases fluid friction and reduces pump output.

Tighten the hose band securely to prevent the hose from disconnecting under high pressure

b) Assembly (Fig.7)

1. Insert the coupling into the discharge hose.
2. Use the clamp and tape (not supplied) and tighten firmly.

Then screw the hose coupling to the pump discharge port [12].

Fig.7

4.4- Before starting engine

4.4.1- Check that both suction hose and discharge hose are properly assembled.
4.4.2- Before starting engine and before each use, ensure that both fuel tank and oil tank are fully filled in. Refill if necessary. (See 3.4 and 3.5 for level check and refill instructions)
4.4.3- Priming the pump

The pump chamber should be completely filled before operating.

Note: Do not operate the pump without priming water or the pump will overheat. Operating the pump dry will destroy the pump seal. If the unit has been operated dry, stop the engine immediately and allow the pump to cool before adding priming water.

Fill water into the self-priming port [13] to make the suction hose and the water pump full of water.

Proceed as follows:

1. Remove cap
Fig.8

2. Fill in with water
Fig.9

3. Replace cap
Fig.10

IMPORTANT: A continual idling or operation without water in the pump will lead to its damage.

So before starting the engine, please make sure that the pump has been refilled water.

If the suction hose strainer appears above the water in the course of operation, stop the engine as soon as possible.

1. Make sure that the joint of the suction hose is tightened. Otherwise the air leakage will lead to no suction or have effect on the power of the pump.
2. Do not install a valve or tap on the discharge hose.

If you proceed with such installation in order to control the water flow, then never turn off the valve or tap during operation

1. Water will not be pumped if the discharged hose is obstructed, the sudden great pressure created inside the pump may damage the pump.
2. If the pump is installed in a location where the discharge hose is likely to be stepped on or pressed, please ensure to cover it with suitable protective covering.
3. Be sure to install the attached filter (strainer) at the head of the suction hose when it is in use.
4. Set the suction hose filter (strainer) under the water, but never allow it to touch the mud or sand.
5. Before use, please check whether each part is loosened or there is any petrol dripping in the fuel tank.
6. Before starting the engine, make sure that there is no object that can get wet near the pump. Remind all bystanders around it that the machine will start working

4.5- Starting the engine

1. Turn the fuel valve (a) ON

Fig.11

1. Completely close the choke lever (14) to OFF position.

Remark: do not use the choke if the engine is warm or the ambient temperature is high

Fig.12

1. Turn the engine switch (5) to ON position.

Fig.13

1. Move the throttle lever downward slightly, just past the idle position.

Fig.14

1. Operate the recoil starter (6).

Pull the starter grip rope lightly until you feel a resistance, then pull briskly until engine starts.

Return the starter rope gently.

Repeat operation if necessary, and until engine starts.

Fig.15

Tips: Hold pump (one hand on handle and one foot on base)

Do not pull starter grip rope over its full length.

Return starter rope gently so as not to damage the recoil starter.

1. As the engine warms up, gradually open the choke (14)

Fig.16

1. Set the throttle lever (16) at the desired speed.

Fig.17

Remarks:

• Hold the engine firmly with your left hand, then pull out the starter handle with your right hand, gently in the beginning until you feel the resistance, and then pull it out rapidly.
• Please do not pull out all the starting rope and do not release it rapidly. Doing so will damage and/or breakdown the starter.
• If you restart the engine after it is stopped, please set the throttle to the "OFF" position.

Troubleshooting

• If after three or four attempts, the engine still does not start, excessive fuel may have drowned the spark plug. You can try to start without the choke, or disassemble the spark plug to dry the electrode which may be submerged in fuel.
• If the electrode is dry upon dismantling (lack of gasoline), close the fuel cock, and then check the sediment cup located under the carburetor.

Remove impurities and then check the gasoline flow by opening the fuel cock and assemble the cup, paying attention to the condition of the seal

After the engine is started, turn on the choke throttle gradually and withdraw the throttle switch.

Leave the engine running for 1-2 minutes at low speed to heat the engine.

4.6- Stopping the engine

4.6.1-In normal use

Please withdraw the throttle switch and leave the engine running for 1~2 minutes at low speed to cool the engine.

1. Move the throttle lever (16) all the way up.

1. Turn the engine switch (5) to OFF position.

Fig.19

1. Turn the fuel valve (a) to OFF position.

Fig.20

4.6.2- In an emergency

In case of emergency: Please stop the engine immediately

To stop the engine in an emergency, turn the engine switch (5) to the OFF position.

4.7- Adjusting the idle speed of the engine

The idle speed of the engine was adjusted in the factory

The user should not attempt to adjust it to avoid any danger.

After the throttle lead is completely released, if the idling speed of the engine is too low or too high, please contact the qualified service person to adjust it.

4.8- After use

Remove the hoses, drain off the water inside the pump and remove the water and impurity substances inside the hoses. Store it in the specified place.

Important! In cold winter, please be sure to drain off the water inside the pump after use. As the temperature outdoors is below zero centigrade, the water inside the pump will be frozen, which may damage the pump.

4.9- High altitude operation

At high altitude, the standard carburetor air-fuel mixture will be too rich.

Performance will decrease, and fuel consumption will increase.

A very rich mixture will also foul the spark plug and cause hard starting.

High altitude performance can be improved by specific modifications to the carburetor.

If you always operate your pump at altitudes above 6,000 feet (1,800 meters) have an authorized water pump dealer perform this carburetor modification.

In any case, engine horsepower will decrease about 3 to 5% for each 1,000 feet (300m) increase in altitude.

Note: When the carburetor has been modified for high altitude operation, the air-fuel mixture will be too lean for low altitude use. Operation at altitudes below 6,000 feet (1,800 meters) with a modified carburetor may cause the engine to overheat and result in serious engine damage.

For use at low altitudes, have an authorized water pump dealer return the carburetor to original factory specifications.

V. OPERATION
