Setting the rotational direction (see figure I)
Only operate the rotational direction switch (9) when
u
the power tool is not in use.
The rotational direction switch (9) is used to change the ro-
tational direction of the power tool. However, this is not pos-
sible while the on/off switch (10) is being pressed.
Right rotation: To drill and to drive in screws, press the ro-
tational direction switch (9) through to the left stop.
Left Rotation: To loosen and unscrew screws and nuts,
press the rotational direction switch (9) through to the right
stop.
Preselecting the Torque
The torque presetting ring (2) can be used to preselect the
required torque in 22 stages. When the correct setting is
used, the bit will be stopped as soon as the screw is driven
flush into the material or as soon as 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.
Setting the operating mode (see figure J)
The operating mode presetting ring (3) can be used to
choose between screwdriving, drilling and impact drilling.
In the "impact drilling" position the overload clutch is deac-
tivated and it is constantly at maximum power.
Mechanical gear selection
Only operate the gear selector (4) when the power
u
tool is not in use.
You can preselect two speed ranges with the gear selector
(4).
First gear:
Low speed range; for working with a large drilling diameter
or for screwdriving.
Second gear:
High speed range; for working with a small drilling diameter.
Always push the gear selector switch as far as it will
u
go. Otherwise, the power tool may become damaged.
Switching on/off
To start the power tool, press and hold the on/off switch
(10).
The worklight (7) lights up when the on/off switch (10) is
lightly or fully pressed, allowing the work area to be illumin-
ated in poor lighting conditions.
The worklight (7) will remain lit for approximately ten
seconds after the on/off switch (10) has been released.
Adjusting the Speed/Impact Rate
You can adjust the speed/impact rate of the power tool when
it is on by pressing in the on/off switch (10) to varying ex-
tents.
Applying light pressure to the on/off switch (10) results in a
low rotational speed/impact rate. Applying increasing pres-
sure to the switch increases the speed/impact rate.

Fully automatic spindle lock (Auto-Lock)
The drill spindle, and therefore the holder (1), are locked
when the on/off switch (10) 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 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 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.
Practical advice
Only apply the power tool to the screw/nut when the
u
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
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
Remove the battery from the power tool before carry-
u
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.
To ensure safe and efficient operation, always keep
u
the power tool and the ventilation slots clean.
