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 may influence operation of the pump negatively and substantial damage.

During installation, the machine must not be running.

All connection piping must be absolutely tight because leaking piping may influence 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 the sealing material such as Teflon tape will ensure airtight assembly.

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

Installation of the suction piping

The suction piping will transport the liquid to be pumped by the pump. Use the suction piping of diameter identical to pump suction connector. For pumping lift with the difference between the pump and the pumped liquid level of more than 4 12 , using of +1/4 " diameter is recommended.

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

In addition, it is highly recommended to install the return valve to prevent pressure leak after turning the pump off and protecting the machine against damage due to pressure surges. The return valve can be connected directly on the pump suction connector or the suction piping input. Installation on the suction piping input is favourable. The suction piping can be easily deaerated by filling with water.

The suction piping input must always be located at least 0.30 m under 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, fishponds banks to avoid 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 of the force piping of at least 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 odourless 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, otherwise the oil low level switch may be activated and starting 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 correct tightness of the bolts and 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 open flame when refuelling. Do not breathe vapours.

Gasoline and engine oil are toxic substances. Do not have gasoline or engine oil and do not breathe vapours. Many direct contact of gasoline and engine oil with skin, and clothes.

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

Do not smoke and work with open flame when refuelling. Do not breathe vapours.

Check oil level before use (see Replacement/check

Filling the pump with water or deaerating of the system

Pour 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 self-suctioning device. It means that for starting, only the pump and not the suction piping must be filled. In 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 with water. It depends on length and diameter of the suction piping.

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

Operation

The gasoline engine pump must not be used with the y point closed.

The pump must not be used without water for longer of time. Dry operation, i.e. without pumping of water, result in substantial damage of the machine.

The gasoline engine pump and the piping system must be acted against freeze and weather conditions.

Flammable substances and things, easily inflammable positive substances must be out of reach of the pump operation. Do not put anything on the engine.

If the engine is in operation, do not refuel or pour oil in it. e pump off before refuelling.

During operation, some parts of the engine pump - e.g. test or exhaust cover - are very hot. To avoid burning, touch the machine during operation and after turning it and cooling down on the designed points only - e.g. on issues and handles.

During 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.

Decommissioning

Transport of the pump with the fuel tank filled is not approved.

Discharge water in the pump from the relevant discharge hole after use. Let the pump dry well 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 improved lifecycle of your machine. The engines consist of the up-to-date technology and many rotary components exposed to substantial mechanic, thermal as well as chemical effect of environment and the combustion process. 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 of liquids with abrasive substances. The recommended accessories filter sand and other similar substances from the liquid effectively and reduce wear and tear and improve lifecycle of the pump.

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 without burnt residues must show 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. Distance of the electrodes must be corrected by 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 with low flash point in any case due to fire and explosion danger.

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

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

Open 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 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 of the engine.

Replacement of the slide locking ring

The slide locking ring is the seal between the pump body and the engine shaft. The ring is a component with natural wear 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 wheel. Then, the slide locking ring may be replaced. Finally, carefully mount the moving wheel of the pump, 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 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 longer time, all water in the pump must be drained. Let the pump dry to avoid corrosion. Drain the fuel tank and the carburettor. Cleaning and preserving of the machine before storing is recommended. Make sure the machine is stored in 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 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 removal of defects may be performed only if the engine is stopped.
