Setting the Torque
With the torque preselection ring 3, the required torque can be preselect-
ed in 10 steps. The inserted tool is stopped as soon as the set torque is
reached.
Position 1:
Lower torque for screwing in screws with small diameter or into soft ma-
terials.
Position 10:
Higher torque for screwing in screws with large diameter or into hard ma-
terials.
Switching On and Off
To start the machine, press the On/Off switch 8 and keep it pressed.
The power light 7 lights up when the On/Off switch 8 is slightly or com-
pletely pressed, and allows the work area to be illuminated when lighting
conditions are insufficient.
To switch off the machine, release the On/Off switch 8.
Adjusting the Speed
The speed of the switched on power tool can be variably adjusted, de-
pending on how far the On/Off switch 8 is pressed.
Light pressure on the On/Off switch 8 results in a low rotational speed.
Further pressure on the switch results in an increase in speed.
Fully automatic spindle locking (Auto-lock)
When the On/Off switch 8 is not pressed, the drill spindle and thus the
tool holder are locked.
This enables screws to be screwed in, even when the battery is empty and
allows for the machine to be used as a screwdriver.
Temperature Dependent Overload Protection
When using as intended for, the power tool cannot be subject to overload.
When the load is too high or the allowable battery temperature of 70 °C is
exceeded, the electronic control switches off the power tool until the tem-
perature is in the optimum temperature range again.
