Transport and storing

• For long-term storing, the machine must be thoroughly cleaned and no unauthorized persons may have access to the machine.
• Secure the machine against turning over before each transport.

Assembly/first commissioning

The gasoline engine pump is installed in a stable cage made from steel tubes with vibration damper. These devices must not be disassembled during operation because they provide stability and reduce vibrations.

General installation instructions
All connection piping must be absolutely tight.
Leaking piping may influence the operation of the pump negatively and cause substantial damage.

During installation, the machine must not be running.

All connection piping must be absolutely tight because leaking piping may influence the operation of the pump negatively and cause substantial damage. Therefore, make screw connections between the pump and the piping and seal with Teflon tape. Use of sealing material such as
Teflon tape will ensure airtight assembly.

Do not overtighten the screw joints to avoid damage. During the installation of the connection piping, make sure the pump is free of any forces, weight, vibration, and stress.

Installation of the suction piping
A filter must be installed at the input of the suction piping to remove coarse impurities from water with the potential of either clogging or damaging the pump.

The suction piping will transport the liquid to be pumped up to the pump. Use the suction piping of diameter identical to the pump suction connector. For a pumping lift with a difference between the pump and the pumped liquid level of more than 4 meters, using +¼‘‘ diameter is recommended.

A filter must be installed at the input of the suction piping to remove coarse impurities from water with the potential of either clogging or damaging the pump.
In addition, it is highly recommended to install the return valve to prevent pressure leaks after turning the pump off and
protecting the machine against damage due to pressure surges.
The return valve can be connected directly to the pump suction connector or the suction piping input. Installation on the suction piping input is favorable. The suction piping can be easily deaerated by filling w ith water.

The suction piping input must always be located at least 0.30 m  under the pumped liquid level to avoid air inlet. In addition to this, pay attention to sufficient distance of the suction piping from soil and streams, rivers, and fishponds banks to avoid the suction of stones, plants, etc.

Installation of the force piping
The force piping transports the liquid to be pumped from the pump to the consumption point. To avoid losses from flow,  using force piping of at least an identical diameter as the pump connector is recommended.

Fixed installation
For fixed installation, attach the gasoline engine pump to a suitable stable supporting surface. To reduce vibrations, it is recommended to insert an anti- vibration material, e.g. rubber layer, between the pump and the supporting surface.

Commissioning

Installation and visual control

Flue gases of the gasoline engine pump contain odorless toxic carbon monoxide that may result in serious health issues and death under extreme conditions. To protect humans and animals, the machine must not be used in poorly ventilated places and not in closed spaces. Generally, avoid breathing of the flue gases.

Check the gasoline engine pump with respect to safety before use. Do not use the machine if damaged.
The gasoline engine pump may only be used in areas without risk of floods.
For each starting of the machine, it is necessary to make sure the pump is installed safely and in a stable position. Always pay attention to a flat surface under the pump, otherw ise the oil low-level switch may be activated and start is not enabled. The gasoline engine pump may only be used in areas without risk of floods.

Select the place of the pump installation so that no environmental damage is caused by leaked fuel or engine oil. If used in fish ponds, pits, construction pits, rivulets, streams, and similar places, the pump must be secured against fall.

Check the gasoline engine pump visually before use of the pump. Pay attention to the correct tightness of the bolts and the perfect condition of all connectors. Do not use the machine if damaged.

Fuel and fuelling/engine oil

The gasoline engine pump is powered by gasoline. Use the fuel specified in the technical data applicable to your product.
Do not smoke and work with an open flame when refueling. Do not breathe vapors.
Gasoline and engine oil are toxic substances. Do not swallow gasoline or engine oil and do not breathe vapors. Avoid any direct contact with gasoline and engine oil with skin, eyes, and clothes.

Do not refuel if the engine is running. Turn the pump off and let it cool for at least five minutes before refueling. During refueling, the machine must be placed on a flat surface in a vertical position to avoid fuel leaks. Refuel in a well-ventilated area only. All leaked gasoline must be first cleaned and then start up the engine.

Do not smoke and work with an open flame when refueling.
Do not breathe vapors.

Check oil level before use (see Replacement/check of oil)

Filling the pump with water or deaerating the system or water in the filling hole of the pump. Check for water leaks. Close the filling hole again to be airtight. It is recommended – but not absolutely necessary – to fill the suction piping with water as well.

The gasoline engine pump is a self-suctioning device. It means that for starting, only the pump and not the suction piping must be filled. Either way, the pump will need some more minutes to draw the pumped liquid. Additional filling of the suction piping will significantly facilitate and fasten the first suction. If the suction piping is not filled with the liquid, it will be perhaps necessary to prime the pump several times w ith w ater. It depends on the length and diameter of the suction piping.

Open potential closures in the force piping (e.g. water cockto release air during suction.

Starting of the engine
Open the gasoline cock to turn the engine on (Fig. A/19).
Set the ignition breaker (Fig. A/10) to the ON position, set the saturator lever (Fig. A/15) in the Start position, and the power controller (Fig. A/12) to the Full throttle position. Then, pull with the starting rope (Fig. A/11) several times until the engine starts. Then, slowly set the saturator lever (Fig. A/15) in the operation position. As soon as the engine starts, suction commences. Now, leave the power controller (Fig. A/12) in the Full throttle position. If the liquid is drawn equally or without any air, the suction is interrupted and the system deaerated. Now, set the power controller (Fig. A/12) according to individual requirements.

Operation

The gasoline engine pump must not be used with the delivery point closed.
The pump must not be used without water for a longer period of time. The dry operation, i.e. without pumping of water, may result in substantial damage to the machine.
The gasoline engine pump and the piping system must be protected against freeze and weather conditions.
Flammable substances and things, easily inflammable or explosive substances must be out of reach of the pump during operation. Do not put anything on the engine.
If the engine is in operation, do not refuel or pour oil into it. Turn the pump off before refueling.

During operation, some parts of the engine pump – e.g. exhaust or exhaust cover – are very hot. To avoid burning injuries, touch the machine during operation and after turning it off until cooling down on the designed points only – e.g. on switches and handles.
During the first 20 hours of operation, the brand-new engine must not be fully loaded. Operation at 2/3 of possible output performance is recommended. Full throttle operation is now permissible for short term only up to 10 minutes – e.g. for starting due to suction operation.

Turning the engine off
Set the power controller (Fig. A/12) to the Idle Throttle position and set the ignition breaker (Fig. A/10) to the OFF position. The pump input is fitted with a valve that prevents the leaking of water from the pump after it is turned off. Stopping the backflow will result in a shorter time for re-suction during the next start. Therefore, the pump must not be primed again during restart.

Decommissioning
Transport of the pump with the fuel tank filled is not approved.
Discharge w ater in the pump from the relevant discharge hole after use. Let the pump dry w ell to avoid damage due to corrosion. Water entrapped in the pump may cause damage if frozen.
If the device is transported, all fuel must be discharged.
Transport of the pump with the fuel tank filled is not approved.

Care and maintenance

If possible, turn the engine off, remove the spark plug shield and let the engine cool down before maintenance. If the engine must be on during maintenance, provide sufficient ventilation because the exhaust fumes are toxic.
Regular maintenance and diligent care reduce the risk of potential operation failures and contribute to the improved lifecycle of your machine. The engines consist of the up-to-date
technology and many rotary components are exposed to substantial mechanical, thermal as well as chemical effects of the environment and the combustion process. The use of correct, high-quality, and clean operation liquids – fuel and engine oil – is prevention against damage to the engine and operation failures.

Abrasive substances in the delivered liquid, such as sand, increase wear and tear and reduce total performance.
Installation of a pre-filter is highly recommended for pumping liquids with abrasive substances. The recommended accessories filter sand and other similar substances from the liquid effectively and reduce wear and tear and improve the lifecycle of the pump.

Oil check and replacement

Check for the oil level before starting.

Oil must be replaced at least annually. Engine oil deteriorates during this period despite the fact the engine is not almost used.
For oil replacement, discharge old oil and pour new oil in the filling hole in the oil tank (for type and quantity of oil – see Technical data). An excessive amount of oil has a negative effect as well – (see the quantity of oil – Technical data).

Diligent care includes an oil level check before use. Use the prescribed oil dipstick for inspection. During the oil level check, the machine must stand flat, turn off, and cool down.  Make sure the oil level does not exceed the maximum quantity and falls under the minimum quantity required as indicated on the dipstick. (For type and quantity of oil – see Technical data).
Please, observe local requirements applicable to the disposal of used oil.

If the engine operates, do not pour engine oil into it.
Before filling the engine oil, turn the pump off and let it cool down for at least 5 minutes. During the pouring of the engine oil, the machine must be placed on a flat surface in a vertical position to avoid engine oil leaks. All leaked engine oil must be first cleaned and then start up the engine.

Do not smoke and work with an open flame when pouring the engine oil. Do not breathe vapors.

Automatic Auto Stop activation (safety feature for low oil level) for low oil level.
This technology automatically turns the engine off when the oil level is lower than the minimum required. The engine can be restarted after a sufficient quantity of engine oil is replenished. When replenishing engine oil, adhere to all instructions related to the engine oil and engine oil check as specified in this guide.

Ignition plug
Cleaning of the ignition plug and correction of distances of the electrodes must be performed in six-month intervals or after 100 hours of operation. First, remove the ignition plug shield before maintenance of the ignition plug. Then, screw the ignition plug out using the ignition plug key. To ensure failure-free operation, the dry ignition plug w without burnt residues must show the distance of the electrodes 0.6 – 0.7 mm.

If necessary, clean the ignition plug. To remove the burnt residues, use a fine wire brush. The distance of the electrodes must be corrected by a slight bending of the electrode. It is recommended to use a new ignition plug in case of strong accumulation or worn electrodes.

Checked, cleaned or a new ignition plug must be screwed first manually to stop. Then, tighten the ignition plug using the ignition plug key. Avoid excessive forces not to damage the ignition plug due to torque. Finally, slide the ignition plug shield back on the ignition plug.

Air filter

To clean the air filter, do not use gasoline or a thinner w ith low flash point in any case due to fire and explosion danger.

If the air filter is clogged, it prevents airflow to the carburetor. To avoid operation failures of the carburetor, an air filter must be regularly checked and cleaned or replaced, if necessary.

Generally, checking the air filter as far as clogging is concerned is recommended before use. Cleaning is required in a three-month interval or after 50 hours of operation. When the pump is operated in a dirty or dusty environment, cleaning must be performed at ten-hour intervals. Use a new air filter in six-month intervals or after 300 hours of operation.

Open the air filter cabinet and remove the air filter before maintenance. Wash the air filter with an inflammable thinner, if necessary – e.g. detergent. To clean the air filter, do not use gasoline or a thinner with a low flash point in any case due to fire and explosion danger. Let the air filter dry after cleaning.
Insert checked, cleaned, or new air filter and close it again.
Do never use the pump without the air filter to avoid increased wear and tear on the engine.

The slide locking ring is the seal between the pump body and the engine shaft. The ring is a component with natural w ear and tear.
If the slide locking ring is defective, water leaks between the engine and the pump body. Demount the pump body, manual starting device, and the pump moving w the heel. Then,  the slide locking ring may be replaced. Finally, carefully mount the moving wheel of the pump, the manual starting device, and the pump body.

Removal of foreign particles from the pump
Coarser particles in the pumped liquid may block the pump body and the pump’s moving wheel. For this case, the pump body can be demounted in order to remove all impurities from the pump moving wheel.

Storing

If the machine is not used for a longer time, all water in the pump must be drained. Let the pump dry to avoid corrosion. Drain the fuel tank and the carburetor. Cleaning and preserving the machine before storing is recommended. Make sure the machine is stored in a dry and frost-proof place.

Failures

If the machine is not used for a longer time, all water in the pump must be drained. Let the pump dry to avoid corrosion. Drain the fuel tank and the carburetor. Cleaning and preserving the machine before storing is recommended. Make sure the machine is stored in a dry and frost-proof place.

Failures

Make sure no water gets in the machine.

We shall not be liable for damage due to unprofessional repair attempts. Damage due to unprofessional repair attempts shall void any warranty claims.

All measures for the removal of defects may be performed only if the engine is stopped.
The following list specifies some potential machine damages, potential reasons, and tips for removal. All measures for the removal of defects may be performed only if the engine is stopped. If you are unable to remedy the defect, please contact either customer service or your sales representative. Overhaul repairs may be performed by authorized personnel only. Please note that warranty claims shall be void in case of damage due to unprofessional repair attempts and we shall not be responsible for any consequent damage.

In case of operation failures, first, check for operator error or other causes not associated with the machine defect – e.g. no fuel.
