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 de-
activated, 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 switch (3)
u
when 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
u
go. Otherwise, the power tool may become
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 approx. 10
seconds after the on/off switch (7) has been re-
leased.
To save energy, only switch the power tool on
when in use.
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.
Applying light pressure to the on/off switch (7)
results in a low rotational speed. Applying increas-
ing pressure to the switch increases 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.

English
This allows screws to be driven in even when the
battery is discharged and enables the power tool
to be used as a screwdriver.
Temperature-dependent overload protection
In normal conditions of use, the power tool can-
not be overloaded. If the power tool is overloaded
or not kept within the permitted operating temper-
ature 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 indicator (8) in-
dicates the state of charge of the battery for sev-
eral seconds. The indicator consists 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

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 BTI accessory range guaran-
tees 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 unin-
tentionally pressing the on/off switch.
To ensure safe and efficient operation, al-
u
ways keep the power tool and the ventilation
slots clean.
