Operation
Starting Operation
Inserting the battery
u Use only original Bosch lithium-ion batteries with the
voltage stated on the type plate of your power tool.
Using other batteries can lead to injuries and pose a fire
hazard.
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 (3) to the middle position
to avoid unintentionally switching it on. Insert the charged
battery (8) into the handle until you feel it engage and it is
flush with the handle.
Setting the rotational direction (see figureC)
u Only operate the rotational direction switch (3) when
the power tool is not in use.
The rotational direction switch (3) is used to change the ro-
tational direction of the power tool. However, this is not pos-
sible while the on/off switch (4) is being pressed.
Right rotation: To drill and to drive in screws, press the ro-
tational direction switch (3) through to the left stop.
Left Rotation: To loosen and unscrew screws and nuts,
press the rotational direction switch (3) through to the right
stop.
Switching on/off
To start the power tool, press and hold the on/off switch
(4).
The lamp (1) lights up when the on/off switch (4) is lightly or
fully pressed, meaning that the work area is illuminated in
poor lighting conditions.
To switch off the power tool, release the on/off switch (4).
Adjusting the Speed
You can adjust the speed of the power tool when it is on by
pressing in the on/off switch (4) to varying extents.
A light pressure on the on/off switch (4) results in a low rota-
tional speed. Increased pressure on the switch causes an in-
crease in speed.
Fully automatic spindle lock (Auto-Lock)
The drill spindle, and therefore the tool holder, are locked
when the on/off switch (4) is not pressed.
This enables screws to be screwed in even when the battery
(8) is empty and allows the power tool to be used as a
screwdriver.
Run-out brake
Upon releasing the on/off switch (4), the drill chuck is
slowed down, which prevents the application tool from con-
tinuing to rotate.
When driving in screws, you should therefore only release
the on/off switch (4) once the screw has been inserted flush
into the workpiece. This way, the head of screw will not pen-
etrate the workpiece.
Battery charge-control indicator
When the on/off switch (4) is pressed in halfway or com-
pletely, the battery charge-control indicator (6) indicates
the charge condition of the battery for several seconds. The
indicator consists of three green LEDs.
LEDs Capacity
3× continuous green light ≥66%
2× continuous green light ≥33%
1× continuous green light <33%
1× flashing green light Reserve
Temperature-dependent overload protection
In normal conditions of use, the power tool cannot be over-
loaded. If the power tool is overloaded or the permitted bat-
tery temperature is exceeded, the electronics of the power
tool will switch off until the temperature returns to within the
optimum operating temperature range.
Protection against deep discharge
The lithium-ion battery is protected against deep discharge
by the "Electronic Cell Protection (ECP)". When the battery
is discharged, the power tool is switched off by means of a
protective circuit: The application tool no longer rotates.
Angled Drill Head (see figure D)
The drill head can be locked in 5 different angle positions.
Push the release button (5) and swivel the tool head to the
required position. Then, let go of the release button (5)
again.
u Before starting operation, check if the drill head is
locked in the respective angle position. This poses a
risk of injury.
Practical advice
u Only apply the power tool to the screw when 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 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
Bosch 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.
Maintenance and Service
Maintenance and Cleaning
u Remove the battery from the power tool before carry-
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.
u To ensure safe and efficient operation, always keep
the power tool and the ventilation slots clean.
