Gear Selection, mechanical

2nd gear:
High speed range; for drilling with small drilling diameter.
Temperature Dependent Overload
Protection
In normal conditions of use, the power tool cannot be over-
loaded. If the power tool is overloaded or not kept within the
permitted battery temperature range, the power output is
reduced or the power tool is switched off. The power tool will
not run at full power output again until the permitted battery
temperature has been reached.
Activation of the temperature-controlled overload protector is
indicated by the LED 14 on the power tool lighting up red.
The LED 14 will go out once the temperature of the tool's bat-
tery is back within the permissible range.
Protection Against Deep Discharging
The lithium-ion battery is protected against deep discharging
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.
Rapid Shut-off
The rapid shut-off feature enables better control of the power
tool. The power tool shuts off in case of sudden and unex-
pected rotation of the power tool around the drilling axis.
The rapid shut-off feature is indicated by a flashing LED on the
power tool.
To restart the machine, release the On/Off switch and
then actuate again.
 Rapid shut-off can trigger only when the
power tool is running at maximum operating
speed and can rotate freely around the drill bit
axis. Choose a suitable work position for this. Otherwise,
rapid shut-off will not be ensured.

Working Advice

 Apply the power tool to the screw only when
it is switched off. Rotating tool inserts can slip off.
An auxiliary tool can be used to remove the screwdriver bit or
universal bit holder.
Belt Clip
With the belt clip 10, the machine can be hung onto a belt.
The user has both hands free and the machine is always at
hand.

Maintenance and Cleaning

 Before any work on the machine itself (e. g.
maintenance, tool change, etc.) as well as dur-
ing transport and storage, remove the battery
from the power tool. There is danger of injury when
unintentionally actuating the On/Off switch.
 For safe and proper working, always keep the
machine and ventilation slots clean.
When the battery is no longer operative, please refer to an
authorised after-sales service agent for Würth power tools.
If the machine should fail despite the care taken in manufac-
turing and testing procedures, repair should be carried out by
a Würth master-Service.
In all correspondence and spare parts orders, please always
