The power light 7 lights up when the On/Off switch 8 is slightly or completely
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, depend-
ing on how far the On/Off switch 8 is pressed.
Light pressure on the On/Off switch 8 results in a low rotational speed. Fur-
ther 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 al-
lows 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 ex-
ceeded, the electronic control switches off the power tool until the tempera-
ture is in the optimum temperature range again.
Protection Against Deep Discharging
The Lithium-Ion battery is protected against deep discharging by the "Elec-
tronic Cell Protection (ECP)". When the battery is empty, the machine is
switched off by means of a protective circuit: The inserted tool no longer ro-
tates.

Working Advice

 Apply the power tool to the screw only when it is switched off. Rotat-
ing tool inserts can slip off.
