Adjusting the Speed
The speed of the switched on power tool can be variably
adjusted, depending on how far the On/Off switch 8 is
pressed.
Light pressure on the On/Off switch 8 results in a low ro-
tational 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 bat-
tery 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 al-
lowable battery temperature of 70 °C is exceeded, the
electronic control switches off the power tool until the
temperature is in the optimum temperature range again.
Protection Against Deep Discharging
The lithium-ion battery is protected against deep dis-
charging by the "Electronic Cell Protection (ECP)". When
the battery is empty, the machine is switched off by
means of a protective circuit: The inserted tool no longer
rotates.

Working Advice

Apply the power tool to the screw only when it is
switched off. Rotating tool inserts can slip off.
