Starting Operation

Inserting the Battery

J 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.
Set the rotational direction switch 8 to the centre
position to protect the power tool against accidental
starting.
Insert the charged battery 7 from the front into the
base of the power tool. Push the battery completely
into the base until the red stripe can no longer be
seen and the battery is securely locked.
Reversing the Rotational Direction
(see figure E)
The rotational direction switch 8 is used to reverse
the rotational direction of the machine. However,
this is not possible with the On/Off switch 9 actu-
ated.
Right Rotation: For drilling and driving in screws,
push the rotational direction switch 8 left to the stop.
Left Rotation: For loosening and unscrewing
screws and nuts, press the rotational direction switch
8 through to the right stop.
Setting the Torque
The required torque can be preselected in 20 steps
with the torque preselection ring 2. With the correct
setting, the insert tool is stopped as soon as the
screw is screwed flush into the material or when the
set torque is reached.
Select a higher setting when driving out screws, or
set to the symbol "Drilling".
Gear Selection, Mechanical
J The gear selector 3 can be actuated at
standstill or when the machine is running.
However, this should not be done while
operating at full load or maximum speed.
Two speed ranges can be preselected with the gear
selector 3.
Gear I:
Low speed range; for screwdriving or working with
large drilling diameter.
Gear II:
High speed range; for working with small drilling
diameter.
If the gear selector 3 cannot be pushed through to
the stop, lightly turn the drill chuck with drill.

Switching On and Off
To start the machine, press the On/Off switch 9
and keep it pressed.
To switch off the machine, release the On/Off
switch 9.
Adjusting the Speed
The speed of the switched on power tool can be var-
iably adjusted, depending on how far the On/Off
switch 9 is pressed.
Light pressure on the On/Off switch 9 results in a
low rotational speed. Further pressure on the switch
results in an increase in speed.
Run-on Brake
When the On/Off switch 9 is released, the chuck
brakes to a stop, thus preventing the run-on of the
tool.
When driving in screws, wait until the screw is
screwed in flush with the material and then release
the On/Off switch 9. By doing so, the head of the
screw does not penetrate into the material.
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.
Working Advice
J Apply the power tool to the screw only
when it is switched off. Rotating tool inserts
can slip off.
When the power tool is electrostatically charged, the
built-in electronic control switches it off. To restart
the power tool, press the On/Off switch 9 again.
Soft Grip
The gripping surface (soft grip) 4 reduces the danger
of slipping and thereby improves the grip on the
machine and the handling.
At the same time, the rubber coating achieves a
vibration-reducing effect.
