Introduction

Thank you for choosing to purchase this quality product. To minimise the risk of injury, we ask you to

always take some basic safety precautions when using this product. Please read this operating manual

carefully and make sure that you understand it.

Keep these operation instructions in a safe place.

Safety instructions

Before using the pump for the first time, read the manual and familiarise yourself with it; otherwise, there

is a risk of serious damages, injuries, or even death.

•Before using the pump for the first time, inspect it to make operation of the pump safer.

•For safety reasons, you must not use the pump to convey flammable or corrosive liquids such

as petrol or acids. Make sure that neither caustic liquids such as seawater, nor chemical solu-

tions, nor alkaline liquids are conveyed.

•Place the pump on a level and solid surface. A water pump placed in an inclined position or

upside down might provoke fuel leakages.

•Only operate the water pump in a well-ventilated place, and respect a minimum distance of 1 m

to other devices. Keep away from sources ignition!

•Keep children and domestic animals away from the water pump. Hot motor parts! Burning

hazard!

•Familiarise yourself with the method of quick stop of the water pump and with the manipulation

of the control parts. It is forbidden to use the water pump without having read the instructions of

this manual.

Attention!

•Petrol is highly flammable and can explode under certain conditions.

•Fill in petrol in a well-ventilated place and with the motor switched off. When filling in and stock-

ing petrol, make sure that no sources of fume or fire such as naked flames, sparks, etc. are or

can get near. Fire hazard! Explosion hazard!

•Do not spill any petrol from the tank. After refuelling, make sure that the tank lid is firmly closed.

•When filling in petrol, avoid spilling it; spilt petrol and petrol fumes are highly flammable. Wipe

up spilt petrol before operation.

•Do not leave the motor run in a closed room or a badly ventilated place. The exhaust fumes of

the motor contain toxic carbon monoxide (CO) that provoke unconsciousness or even death.

Danger of suffocation!

Preparing the commissioning

Connecting the water admission hose

•Use a customary hose, hose connection, and clamp. The water admission hose must be through

and not be kinked. The length of the hose should not exceed the length absolutely required.

The lower the distance to the water surface is, the bigger is the suction effect.

•The suction time varies as a function of the length of the water admission hose. The filter cor-

responding to the water pump should be connected at the end of the water admission hose with

the help of a hose clamp.

Attention!

•Attach the filter firmly to the water admission hose before pumping. The filter will rinse out con-

taminations that block the passage and could damage the impellers.

•Make sure that the hose connection and clamp are safely installed to avoid any intake of air and

a consequential fall of the pump power. A loose water admission hose will reduce the power of

the water pump and the self-aspiration feature.

Connecting the water outlet hose

Use a customary hose, hose connection, and clamp. A short hose with large diameter is best. A long

hose with small diameter will increase the flow resistance and reduce the power of the water pump.

Note! Tighten the clamp to avoid it falling off with the pressure increasing.

Controlling the motor oil level

Attention!

•The quality of the motor oil is one of the decisive parameters defining the power and service life

of the motor. Neither use dirty motor oil nor vegetable oil.

•Control the motor oil level with the motor being switched off and the pump standing on a firm,

level surface.

•Only use motor oil SAE 15 W/40 mineral for winter/summer.

Motor oil pressure switch

•The motor oil pressure switch is meant to avoid a damage of the motor due to too low an oil

level. Before the motor oil level inside the crankcase falls beneath the safety mark, the motor is

switched off automatically (even with the main switch being set to “ON”). Whenever the motor

stops and cannot be started again, first check the oil level.

•For this purpose, screw out the oil gauge and wipe it clean; then re-stick it into the oil orifice

without screwing it in, then take it out again to read the oil level. In case the oil level is too low,

top up with the correct type of oil until the oil level reaches the upper end of the oil orifice.

Controlling the fuel level

•Remove the tank lid and check the fuel level; if it is too low, top up.

•Only use the petrol indicated in the manual (we recommend using non-leaded petrol).

•Do not use any combination of motor oil and petrol or dirty petrol. Avoid that dirt, dust, or water

get into the fuel tank.

Attention!

•Petrol is highly flammable and can explode under certain conditions.

•Only top up with petrol with the motor being switched off and in a well-ventilated place. In the

place of topping up, smoking and naked flames, sparks, etc. must absolutely be avoided.

•Close the tank lid firmly again after topping up.

•Avoid that petrol be spilt when filling petrol in; petrol and petrol fumes are highly flammable.

Wipe up spilt petrol with a cloth before operation.

•Do not leave the pump operate in a closed room; the exhaust pipes of the motor contain toxic

carbon monoxide that provoke unconsciousness or even death.

•Avoid repeated inhalation of petrol fumes and any contact of petrol with your skin.

•Store petrol out of children’s reach.

Controlling the air filter element

Remove the winged nut, washer, and cover. Check the filter insert; if it is dirty or clogged, clean it.

Attention! Do not let the motor run without installed air filter; otherwise, dirt and other contamina-

tions can penetrate the motor through the carburettor, provoking an early wear of the motor.

Controlling the water level inside the pump

Before the pump is used, it must be filled with a sufficient quantity of water.

Attention! Never operate the pump without water filled it; otherwise, it will overheat, and the gas-

kets of the pump will be destroyed. In case the pump is empty and has run hot, stop the motor, wait until

it has cooled down, then fill in new water.

Operation

Before the operation

•For your own safety and for a maximum of service life of your device, it is vital to take a few

minutes for checking the condition of the device; after that, you can operate it. Do not ignore

any problem found; repair it or have a specialist repair it.

•Make sure that the pump stands on an even surface and that the switch of the motor is set to

the “OFF” position.

•To avoid fire hazard, keep the pump away from walls and other devices a minimum distance of

1 m. Do not place flammable objects near the motor.

•The exhaust fumes contain toxic carbon monoxide. Avoid inhaling the exhaust fumes. Never let

the engine run inside a closed garage or another closed area!

Attention!

•In case you do not maintain the pump correctly or do not repair any problem before further use,

this might lead to dysfunctions and to serious injuries.

•Before every operation, visually examine the pump and repair any problem found.

Controlling the condition of the pump

•Inspect the pump to find damages.

•Search for signs of oil or petrol leakage under the pump and around it.

•Remove excesses of dirt and deposits, particularly around the exhaust pipe and hand starter.

Controlling the suction hose and pressure hose

•Check the general state of all hoses. Make sure that the hoses are ready for use before con-

necting them to the pump. Keep in mind that the suction hose needs to have a (spiral) reinforce-

ment.

•Check the condition of the seal washer inside the suction hose connection point.

http://www.aoyue.eu 04 2023-1

http://www.teichtip.de

•Check if the hose connections and clamps are correctly attached.

•Check if the filter is in good condition and correctly installed on the suction hose.

Controlling the motor

•Check the oil level. To avoid any sudden switching off caused by the motor oil alert system,

always check the motor oil level before operation.

•Check the air filter. A dirty air filter hinders the air supply to the carburettor and reduces the

power of the motor and pump.

•Check the petrol level. Starting with the tank filled up helps to avoid or reduce interruptions of

the operation due to the need of refuelling.

Starting the motor

1. Prepare the pump and fill in water.

2. Switch the petrol tap to the “ON” position.

3. For starting a cold motor, set the throttle to the “CLOSED” position. For starting a warm motor,

the throttle should be set to the “OPEN” position.

4. Move the gas lever from the “OFF” position towards “ON” for approx. a ⅓ of the distance.

5. Set the motor switch to the “ON” position.

6. Pull the starter handle slightly until you feel a resistance, then pull it speedily. The starter handle

must not rebound and hit against the motor. Guide it back with caution to avoid any damage of

the starter.

7. If, when starting the motor, the throttle lever is set to the “CLOSED” position, set it gradually to

the “OPEN” position as soon as the motor has become warm.

Setting the speed of the motor

After starting the motor, set the gas lever to “Fast” for the pump to prime itself, and check the output of

the pump. The power of the pump is controlled via the adjustment of the speed. By moving the gas lever

to “Fast,” the power of the pump is increased; by moving the gas lever to “Slow,” the power of the pump

is reduced.

Switching the motor off

To perform an emergency switch-off, turn the motor switch to “OFF.” For normal switch-off, proceed as

follows:

1. Move the gas lever to the lowest position.

2. Set the motor switch to the “OFF” position.

3. Set the petrol tap to the “OFF” position.

4. After use, open the water drain tap and empty the pump chamber. Remove the water fill-in cap

and rinse the pump chamber with clean, fresh water. Then screw the water fill-in cap and water

drain tap on again.

Note! After an automatic emergency switch-off, the motor switch must be set to the “OFF” position by

the user.

Maintenance and care

Keeping the water pump in an optimal condition requires regular checks and adjustments. Regular

checks extend the service life of the device considerably. The following maintenance chart shows you

the frequency of the maintenance jobs to do and the type of maintenance to perform.

Attention! Switch off the motor before any maintenance! If you absolutely need to perform mainte-

nance on a running motor, only work in a well-ventilated room. Exhaust fumes contain carbon monoxide;

this is a toxic gas that may cause unconsciousness or even death.

Note! Dispose of used oil in accordance with the national regulations.

Maintaining the air filter

A dirty air filter reduces the quantity of air in the carburettor. To avoid problems with the carburettor,

clean the air filter on a regular basis. Clean it more often under dusty conditions.

Attention! Do not clean the air filter with petrol or another highly flammable liquid; otherwise, there

is a risk of fire or explosion.

Attention! Do not operate the motor without the air filter installed; otherwise, the device sucks in

dirt and dust, which might lead to an early wear.
