the further proceedings, you should carry out the following steps: Remove the battery pack from the power tool socket!
ATTENTION! All the operations mentioned in this point must be realised with the power supply off - the battery must be discon-
nected from the tool!
Safety recommendations for battery loading
Attention! Before loading may start make sure the body of the charger, the cable and the plug are not broken or damaged. It
is prohibited to use a damaged loading dock and charger! For the purpose of loading batteries only the charging dock and the
charger provided may be used. Using another charger may be a cause of fi re or damage the tool. Batteries may be charged only
in a dry room, protected from unauthorised persons, particularly children. Do not use the charging dock and the charger without
permanent supervision of an adult! If it is necessary to leave the room where loading is taking place, it is required to disconnect the
charger from the mains, removing the charger from the mains socket. In case when smoke comes out of the charger, or a strange
smell is emitted, etc., it is required to immediately remove the plug of the charger from the mains socket!
The drill and automatic return screwdriver is provided with an unloaded battery, so before work may commence, it is required
to charge it following the procedure below, using the charger and charging dock provided. Li-ION batteries do not show the so
called "memory eff ect", so it is allowed to charge them at any moment. However, it is recommended to discharge them during
normal work, and then load them to their full capacity. If due to the nature of the task it is not possible to do so each time, then it
is required to do it at least from time to time. Under no circumstances is it allowed to discharge the batteries short-circuiting the
electrodes, since this would cause irreversible damage! It is also prohibited to check the load of the batteries, short-circuiting the
electrodes for sparking.
Storage of the battery
In order to prolong the life of the battery, it is required to provide adequate storage conditions. The batteries can go through ap-
proximately 500 „loading - discharging" cycles. The battery must be stored between 0 and 30°C, at the relative humidity of 50%. In
order to store the battery for a prolonged period, it is required to charge it to approximately 70% of its capacity. In case of prolonged
storage, it is required to recharge the battery once a year. Do not permit excessive discharging of the battery, since this would
reduce its life and may cause irreversible damage.
During storage, the battery will be gradually unloading due to leakage conductance. The process of automatic unloading depends
on the temperature of storage, since the higher the temperature, the fastest the process. In case of incorrect storage of batteries,
there is a danger of electrolyte leakage. In case of leakage, it is required protect the leakage with neutralizing agent. In case of
contact of electrolyte with the eyes, it is required to rinse the eyes abundantly, and then immediately seek medical assistance. It
is prohibited to use a tool with a damaged battery.
In case the battery is completely worn out, it is required to deposit it at a special point dedicated to disposal of such waste.
Transport of the batteries
Lithium-ion batteries are in accordance with legal regulations treated as dangerous waste. The user of the tool may transport the
tool with the battery or only batteries by land. Then no additional conditions must be complied with. In transport is realised by third
parties (for example dispatch through courier service), then it is required to proceed in accordance with regulations for transport
of dangerous materials. Before shipment, contact an authorised person.
It is prohibited to transport damaged batteries. During transport the battery must be removed from the tool, and the exposed
contacts protected, e.g. with insulating tape. Protect the batteries so that they do not move inside the package during transport. It
is also required comply with the national regulations for transport of dangerous materials.
Charging the Battery
Caution! Disconnect the charger plug from the mains before charging. In addition, clean the battery and battery clamps of dirt
and dust with a soft, dry cloth or brush.
Disconnect the battery from the tool.
Slide the battery into the charger socket (V).
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 charger 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.
The tool has a built-in charge indicator. The LEDs will light up by pressing the power switch, 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.
Mounting and replacing of the saw blade (II)
You should check whether the blade is not damaged, cracked, whether the cutting teeth are not broken, etc. In the case of dam-
