Safety instructions for battery charging
Caution! Before starting charging, make sure that the charger's body, cables and plug are not cracked or
damaged. It is forbidden to use a damaged product.
Charging can only be carried out indoors, in a dry room, protected against unauthorised access, especially
children. Do not perform any charging without constant supervision of an adult! If you need to leave the
room where charging is taking place, stop the process by disconnecting the charger from the product and the
mains. If the product generates any smoke, strange odour, etc., immediately stop the charging process and
disconnect the charger. The product may require charging before the fi rst use. Li-po (lithium-polymer) batteries
do not have the so-called "memory eff ect", which means they can be recharged at any time. However, it is
recommended to discharge the battery during normal operation and then charge it to full capacity. If, due to the
nature of work, it is not possible to use the battery in such a manner every time, it should be done at least every
several work cycles. Never discharge any batteries by short-circuiting the battery plates, as this will cause
irreparable damage! In addition, do not check the battery charge status by short-circuiting the electrodes and
checking their sparking.
Only the welding cables supplied with the product should be used for welding. It is not allowed to use other
cables or modify those supplied with the product. During welding, a high current is transmitted through the
welding cable. Incorrectly selected or modifi ed cables can lead to an electric shock, fi re, burns, or other inju-
ries. Connect the welding and other cables only for the duration of the product's use. Do not store the product
with its the cables still connected. This can cause short circuit and damage to the product, an electric shock,
fi re, or even explosion.
Storing the battery
Ensure proper storage conditions to extend the battery's life. The battery can last for approximately 500
charge-discharge cycles. Store the battery at a temperature ranging from 0ºC to 30ºC at a relative air humidity
of 50%. Charge the battery to approx. 70% of its total capacity to store it for a longer period of time. In case
of prolonged storage, the battery should be periodically charged once a year. Do not over-discharge the bat-
tery 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 temperature – 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 event of electrolyte contact with eyes, rinse
eyes thoroughly with water, and immediately seek medical attention. It is not allowed to use the unit with a
damaged battery. If the battery is completely used, return it to a professional waste disposal centre.
Transporting the batteries
Lithium-polymer batteries are considered hazardous goods according to legal regulations. The user of the tool
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 entrust transport to third parties (e.g. a courier company), follow the regula-
tions 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 batter-
ies from the product and secure the exposed contacts, e.g. 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.
