Changing the Tool (see figure B)
❏ Before any work on the power tool,
remove the battery.
Inserting

push the insert tool to the stop into the tool holder 2.
The insert tool is automatically locked.
Removing
Pull the locking sleeve 1 forward and remove the
insert tool.
Dust/Chip Extraction
Dusts from materials such as lead-containing coat-
ings, some wood types, minerals and metal can be
harmful to one's health. Touching or breathing-in
the dusts can cause allergic reactions and/or lead to
respiratory infections of the user or bystanders.
Certain dusts, such as oak or beech dust, are con-
sidered as carcinogenic, especially in connection
with wood-treatment additives (chromate, wood pre-
servative). Materials containing asbestos may only
be worked by specialists.
• Provide for good ventilation of the working place.
• It is recommended to wear a P2 filter-class respi-
rator.
Observe the relevant regulations in your country for
the materials to be worked.
Starting Operation

Inserting the Battery

❏ Use only original Würth lithium ion batter-
ies with the voltage listed on the name-
plate of your power tool. Using other
batteries can lead to injuries and pose a fire haz-
ard.
☞
Note: Use of batteries not suitable for the
machine can lead to malfunctions of or cause
damage to the power tool.
Reversing the Rotational Direction
(see figure C)
The rotational direction switch 4 is used to reverse
the rotational direction of the machine. However,
this is not possible with the On/Off switch 5 actu-
ated.
Right Rotation: For drilling and driving in screws,
push the rotational direction switch 4 left to the stop.
Left Rotation: For loosening or unscrewing screws,
push the rotational direction switch 4 right to the
stop.

Setting the Torque
With the torque selector switch 6, you can preselect
the required torque in 8 steps. When the torque set-
ting is adjusted correctly, the insert tool is stopped as
soon as the screw is driven flush into the material or
when the set torque is reached. In the "
the safety clutch is deactivated; e.g., for drilling.
In left rotation the safety clutch is deactivated.
Switching On and Off
To start the machine, press the On/Off switch 5
and keep it pressed.
To switch off the machine, release the On/Off
switch 5.
Adjusting the Speed
The speed of the switched on power tool can be var-
iably adjusted, depending on how far the On/Off
switch 5 is pressed.
Light pressure on the On/Off switch 5 results in a
low rotational speed. Further pressure on the switch
results in an increase in speed.
Fully automatic spindle locking
When the On/Off switch 5 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 temperature is in the optimum
temperature range again.
Protection Against Deep Discharg-
ing
The Li-ion battery is protected against deep dis-
charging. When the battery is empty, the machine is
switched off by means of a protective circuit: The
inserted tool no longer rotates.
Angle Selection of Drill Head
(see figure D)
The drill head can be locked in 5 different angle
positions. Push the release button 7 and swivel the
tool head to the required position. Then, let go of the
release button 7 again.
❏ Before starting operation, check if the drill
head is locked in the respective angle
position. Danger of injury.
