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 of the batteries
Attention! Before loading, it is required to disconnect the charger charging dock from the mains removing the plug of the charger
from the mains socket. Furthermore, it is required to clean the battery and its contacts, removing dirt and dust with a soft and dry
cloth.
Disconnect the battery from the tool.
Connect the plug of the charger to the battery socket (II).
Connect the charger to the mains socket.
The diode of the battery will go on, which indicates the beginning of the loading process.
Once the loading process has fi nished, the diode turn the colour from red to green.
It is required to remove the plug of the charger from the mains socket, and disconnect the plug of the charger from the battery.
Adjustments of torque
Torque is adjusted with the ring located behind the chuck (III). The higher the adjusted number, the higher the torque of the auto-
matic return screwdriver. Do not set a higher torque than necessary for a correct work. Otherwise, the threads may be damaged. In
case screws are driven directly into the material, it is required experiment with adequate torque, realising tests on waste material.
If the maximum torque, which is safe for the given connection, is unknown, it is required set the lowest value, and then increase
it until the value which is appropriate for the given task has been reached. When the automatic return screwdriver reaches the
maximum set torque, the overload clutch will be activated, and it is required to stop tightening the bolt.
In case the tool is used to drill holes, it is required to set the ring to the drill symbol, and then the overload clutch will be deactivated,
and the maximum torque will be transmitted to the drill.
Attention! Do not use settings indicated with numbers for drilling. Activation of the overload clutch during drilling may cause dam-
age to the material or the drill and increases the risk of injuries.
Installation of drill bits in the drill chuck
Select an adequate drill bit with a cylindrical drill shank.
Place the drill bit in the chuck. Hold the rear part of the chuck with one hand and tighten the front part of the chuck with another
hand until the drill bit is secured (IV).
Select the highest torque.
Adjustment of the direction of rotation
Place the selector of rotation to R – right rotation or L – left rotation (V).
Attention! The direction of rotation may be changed only if the power supply is off ! It is prohibited to change the direction of rota-
tion during operation of the drill and screwer!
Installation of screwdriver bits in the drill chuck
Place a bit holder in the drill chuck and install an adequate bit. (VI)
