charged once a year. Do not over-discharge the battery as this will shorten its life and may cause irreparable damage.
During storage, the battery will gradually discharge due to leakage. The self-discharge process depends on the storage tempera-
ture – the higher the temperature, the faster the discharge process. If the batteries are stored incorrectly, the electrolyte may leak.
In case of leakage, secure the leak with a neutralising agent. In the case of electrolyte contact with eyes, rinse eyes thoroughly
with water, and immediately seek medical attention. It is not allowed to use the device with a damaged battery. If the battery is
completely worn, return it to a specialist waste disposal centre.
Transport of batteries
Lithium-ion batteries are treated as hazardous materials, according to legal regulations. The user of the device can transport the
product together with the battery and the batteries alone, by land. In that case, no additional conditions have to be met. If you en-
trust transport to third parties (e.g. a courier company), follow the regulations regarding the transport of hazardous goods. Before
shipping, please contact a properly qualifi ed person. It is not allowed to transport damaged batteries. For the duration of transport,
remove the demountable batteries from the product, secure the exposed contacts, for example by covering them with insulation
tape. Protect the batteries in the packaging in such a way that they do not move inside the packaging during transport. National
regulations for the transport of hazardous materials must also be observed.
Charging the battery
Caution! Before charging, disconnect the power unit from the mains by removing the plug from the mains socket. In addition, clean
the battery and battery clamps of dirt and dust with a soft, dry cloth.
The battery has a built-in charge indicator. The LEDs will light up by pressing the button (II), the more of them come on, the more
charged the battery is. If the LEDs do not light up when the button is pressed, the battery is discharged.
Disconnect the battery from the tool.
Slide the battery into the charger socket (III).
Plug the charger into a mains socket.
The red LED will light up, which indicates the charging process.
When charging is complete, the red LED will turn off and the green LED will light up to indicate that the battery is fully charged.
Pull the power unit plug out of the mains socket.
Pull the battery out of the charging station by pressing the battery clamp button.
Caution! If the green LED lights up when the charger is connected to the mains, the battery is fully charged. In this case, the
charger will not start the charging process.
Pumping
Place the free end of the hose connected to the pump inlet in a container with the liquid to be pumped. Make sure that the end of
the hose is under the surface of the liquid throughout the entire pumping process.
Place the free end of the hose connected to the pump outlet in the container to which the liquid is to be pumped. Make sure that
the hose outlet is not out of the container until the end of the pumping process.
Set the pump power switch to the on position – I. The pump will start operating. Control the pumping process.
If the pump starts to run "dry", e.g. due to pumping of the entire liquid from the source container or when the liquid level falls below
the end of the inlet hose, it will stop automatically to avoid overheating.
However, do not allow dry running as this will shorten the service life of the pump.
When pumping is complete, set the pump power switch to the off position – O, which will stop the pump operation.
If any signs of malfunction occur during operation, such as increased noise, increased vibrations, unexpected stoppage of the
liquid fl ow, immediately turn off the pump with the power switch, remove the battery and check the cause of the malfunction It is
forbidden to resume operation without rectifying the causes of malfunction.
Proceed with maintenance after fi nishing work.
MAINTENANCE, TRANSPORT AND STORAGE
Clean the housing of the pump with a slightly damp, soft cloth, then dry the housing or leave it to dry. Check the permeability of
the ventilation openings and, if necessary, clean it with a soft paint brush, a soft plastic brush or a compressed air stream at a
pressure of not more than 0.3 MPa.
Do not use sharp objects, abrasives, corrosive agents, alcohol or solvents to clean the device.
Disconnect the hoses from the pump and gravitationally remove any residual liquids from them. If the pump was used with oil, it
should be cleaned with an aqueous oil removal agent. Pump a few litres of this liquid into the pump and then pump the water until
the clean water will escape from the pump outlet. It is recommended to use separate hoses for oil and water. Store the product
disassembled in dry, shaded and well-ventilated places. Ensure that the storage room protects the device from unauthorised
access, especially by children. It is recommended to store and transport the product in the packaging it was delivered in. Remove
the battery from the device for its transport and storage.
