handle until you feel it engage and it is flush with
the handle.
Setting the rotational direction (see figure H)
The rotational direction switch (6) is used to
change the rotational 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 rotational 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
English
The torque presetting ring (2) can be used to
preselect the required 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
Mechanical gear selection
Only operate the gear selector (3) when the
u
power tool is not in use.
You can preselect two speed ranges with the gear
selector (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 switch as far
u
as it will go. Otherwise, the power tool may be-
come damaged.
Switching on/off
English
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 illuminated in poor lighting conditions.
The worklight (9) will remain lit for approximately
ten seconds after the on/off switch (7) has been
released.
Adjusting the Speed
English
You can adjust the speed of the power tool when
it is on by pressing in the on/off switch (7) to vary-
ing extents.
A light pressure on the on/off switch (7) results in
a low rotational speed. Increased pressure on the
switch causes an increase in speed.

Fully automatic spindle lock (Auto-Lock)
The drill spindle, and therefore the holder (1), are
locked when the on/off switch (7) is not pressed.
This enables screws to be screwed in even when
the battery is empty and allows the power tool to
be used as a screwdriver.
Temperature-dependent overload protection
In normal conditions of use, the power tool cannot
be overloaded. If the power tool is overloaded or
not kept within the permitted operating temperat-
ure 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
operating temperature has been reached.
Battery charge indicator
English
When the on/off switch (7) is pressed in halfway
or completely, the battery charge-control indicator
(8) indicates the charge condition of the battery
for several seconds. The indicator consists of
three green LEDs.
LEDs
3× continuous green light
2× continuous green light
1× continuous green light
1× flashing green light
Practical advice
English
Only apply the power tool to the screw when
u
the tool is switched off. Rotating application
tools can slip off.
After working at a low speed for an extended
period, you should operate the power tool at the
maximum speed for approximately three minutes
without load to cool it down.
When drilling into metal, only use sharpened HSS
drills (HSS = high-speed steel) which are in per-
fect condition. The Berner accessory range guar-
antees 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.
Maintenance and servicing
Maintenance and cleaning
Remove the battery from the power tool be-
u
fore carrying out work on the power tool (e.g.
maintenance, changing tool, etc.). The bat-
tery should also be removed for transport and
storage. There is risk of injury from unintention-
ally pressing the on/off switch.
