Charging the battery

Open the charging socket cap. Connect the Micro USB plug of 

the cable supplied with the screwdriver to the battery charging 

socket. Put the USB plug into a USB socket on your computer 

or in a charger equipped with such a socket with an output cur-

rent of not less than 0.3 A. The LED near the charging socket 

will start 

fl

 ashing, which means the beginning of the charging 

process. When the battery is fully charged, the LED will be lit 

continuously. When the battery is fully charged, disconnect the 

screwdriver from the charger and cover the charging socket with 

the cap. Leaving the screwdriver connected to the charger will 

cause premature wear of the battery. If, when connected to the 

charger, the LED near the charging socket is lit continuously, it 

means that the battery is fully charged. In this case, disconnect 

the screwdriver from the charger immediately.      

Placing screwdriver bits in the holder

Place the selected screwdriver bit in the screwdriver socket. 

The bits should be selected so that they 

fi

 t into the socket of 

the screw as good as possible. This will prevent damage to the 

screw head, which may make it impossible for the screw to be 

screwed in or unscrewed. 

Setting the rotation direction

The rotation direction switch is also the ON/OFF switch. Press 

and hold the switch to start the screwdriver rotation. Pressing 

the switch on the front of the button will screw in the screws with 

right-hand thread, and pressing the switch on the back of the 

button will unscrew the screws with right-hand thread. Releas-

ing the pressure on the switch stops the screwdriver rotation. 

The screwdriver can also be used as an ordinary screwdriver. 

The switch does not need to be pressed in this case. A higher 

torque is generated then, compared to the electric drive. Do not 

overload the screwdriver in manual mode to avoid damaging it.   

PRODUCT USE

Before starting work, check that the tool is starting and running 

evenly at idling speed. Any irregularities observed are a signal for 

inspection or repair at an authorised service centre. 

Screwing - unscrewing 

Insert the appropriate bit into the bit holder. Select the direction 

of rotation with the switch. Then place the bit in the screw socket 

and press the switch. The tool will continue to work as long as 

the switch is pressed.

Drilling

Due to too low a torque, the product is not suitable for drilling.

Additional notes

When working, do not exert too much pressure on the workpiece 

and do not make sudden movements in order not to damage the 

bit and the screwdriver. Take regular breaks during work. Do not 

overload the tool, the temperature of the external surface must 

never exceed 60

O

C. After 

fi

 nishing work, switch o

ff

  the screwdriv-

er and perform activities related to maintenance and inspection. 

The declared total vibration value has been measured using the 

standard test method and can be used to compare one tool to 

another. The declared total vibration value can be used in the 

initial exposure assessment. Caution! The vibration emission 

during tool operation may di

ff

 er from the declared value, depend-

ing on the manner the tool is used. Caution! Safety measures 

to protect the operator, which are based on an assessment of 

exposure under actual conditions of use (including all parts of the 

work cycle, such as the time when the tool is switched o

ff

  or idle 

and the activation time), must be speci

fi

 ed.  

MAINTENANCE AND OVERHAUL

Clean the tool casing with a soft, slightly damp cloth and then dry 

with a soft cloth. After the work is 

fi

 nished, the technical condition 

of the tool should be checked by external visual inspection. Any 

abnormality found during this inspection or the operation require 

servicing at an authorized service agent’s.

This symbol indicates that waste electrical and electronic equipment 

(including batteries and storage cells) cannot be disposed of with 

other types of waste. Waste equipment should be collected and 

handed over separately to a collection point for recycling and 

recovery, in order to reduce the amount of waste and the use of natural 

resources. Uncontrolled release of hazardous components contained 

in electrical and electronic equipment may pose a risk to human health 

and have adverse e

ff

 ects for the environment. The household plays an 

important role in contributing to reuse and recovery, including recycling 

of waste equipment. For more information about the appropriate recycling 

methods, contact your local authority or retailer.
