Switching On and Off
To start the machine, press the On/Off switch 12 and keep
it pressed.
The LED 10 lights up when the On/Off switch 12 is halfway
or fully pressed, and enables illumination of the screwing loca-
tion in unfavourable light conditions.
To save energy, only switch the power tool on when using it.
Adjusting the Speed
The speed of the switched-on power tool can be variably
adjusted, depending on how far the On/Off switch 12 is
pressed.
Light pressure on the On/Off switch 12 results in a low rota-
tional speed. Further pressure on the switch results in an
increase in speed.
Setting the Torque
With the torque preselection ring 3, the required torque can
be preselected in 20 steps. The inserted tool is stopped as
soon as the set torque is reached.
Gear Selection, mechanical
The gear selector 4 can be actuated at stand-
still or when the machine is running. However,
this should not be done while operating at full
load or maximum speed.
1st gear:
Low speed range; for working with large drilling diameters.
2nd gear:
High speed range; for drilling with small drilling diameter.
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 bat-
tery temperature range is exceeded, the speed is reduced.
The power tool will not run at full speed until reaching the
allowable battery temperature.
Activation of the temperature-controlled overload protector is
indicated by the LED 9 on the power tool lighting up red. The
LED 9 will go out once the temperature of the tool's battery 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 5, 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
include the article number given on the type plate of the
machine.
The current spare parts list for this power tool can be viewed
