Inserting the battery
Note: The use of batteries unsuitable for your power tool can
lead to malfunctions or damage to the power tool.
Set the rotational direction switch (6) to the middle position to
avoid unintentionally switching it on. Insert the charged battery
(5) into the handle until you feel it engage and it is flush with
the handle.
Setting the rotational direction (see figure H)
Only operate the rotational direction switch (6)
r
when the power tool is not in use.
The rotational direction switch (6) is used to change the rota-
tional direction of the power tool. However, this is not possible
while the on/off switch (7) is being pressed.
Right rotation: To drill and to drive in screws, press the ro-
tational direction switch (6) through to the left stop.
Left Rotation: To loosen and unscrew screws and nuts,
press the rotational direction switch (6) through to the right
stop.
Preselecting the Torque
The torque presetting ring (2) can be used to preselect the re-
quired torque in 15 stages. When the correct setting is used,
the application tool will be stopped when the screw is driven
flush into the material or once the set torque has been
reached. In position the overload clutch is deactivated,
e.g. for drilling.
When unscrewing screws, it may be advisable to select a
higher setting or the symbol.
Mechanical gear selection
Only operate the gear selector switch (3) when
r
the power tool is not in use.
You can pre-select two speed ranges with the gear selector
switch (3).
Gear I:
Low speed range; for screwdriving or working with a large
drilling diameter.
Gear II:
High speed range; for working with a small drilling diameter.
Always push the gear selector as far as it will go. Other-
r
wise, the power tool may become damaged.
Switching on/off
To start the power tool, press and hold the on/off switch (7).
The worklight (9) lights up when the on/off switch (7) is
lightly or fully pressed, allowing the work area to be illumin-
ated in poor lighting conditions.
The worklight (9) will remain lit for approx. 10 seconds after
the on/off switch (7) has been released.
Adjusting the speed
You can adjust the speed of the power tool when it is on by
pressing in the on/off switch (7) to varying extents.
Applying light pressure to the on/off switch (7) results in a low
rotational speed. Applying increasing pressure to the switch in-
creases the speed.
Fully automatic spindle lock (Auto-Lock)
The drill spindle, and therefore the holder, are locked when
the on/off switch (7) is not pressed.
This allows screws to be driven in even when the battery is dis-
charged and enables the power tool to be used as a screw-
driver.
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 operating temperature range, the power output is re-
duced or the power tool is switched off. The power tool will
not run at full power output again until the permitted operating
temperature has been reached.
Battery charge indicator
When the on/off switch (7) is pressed in halfway or com-
pletely, the battery charge indicator (8) indicates the state of
charge of the battery for several seconds. The indicator con-
sists of three green LEDs.
LED
Continuous lighting 3 x green
Continuous lighting 2 x green
Continuous lighting 1 x green
Flashing light 1 x green
Practical advice
Only apply the power tool to the screw/nut
r
when the tool is switched off. Rotating tool inserts
can slip off.
After working at a low speed for an extended period, you
should operate the power tool at the maximum speed for ap-
proximately three minutes without load to cool it down.
When drilling into metal, only use sharpened HSS drills (HSS
= high-speed steel) which are in perfect condition. The Würth
accessory range guarantees appropriate quality.
Before screwing larger, longer screws into hard materials, it is
advisable to pre-drill a pilot hole with the core diameter of the
thread to approx. 2/3 of the screw length.
