Operation
Starting Operation
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 (8) into the handle until you feel it engage and it is
flush with the handle.
Setting the rotational direction (see figure C)
Only operate the rotational direction switch (6) when
u
the power tool is not in use.
The rotational direction switch (6) 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 (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.
Setting the operating mode
Drilling
Set the operating mode presetting ring (4) to
the "drilling" symbol.
Screwdriving
Set the operating mode presetting ring (4) to
the "screwdriving" symbol.
Set the torque presetting ring (3) to the re-
quired torque.
Impact drilling
Set the operating mode presetting ring (4) to
the "impact drilling" symbol.
Pre-selecting the torque
The torque presetting ring (3) can be used to pre-select the
required torque in 20 stages. Once the set torque has been
reached, the application tool will be stopped.
Mechanical gear selection
Only operate the gear selector (5) when the power
u
tool is not in use.
You can preselect two speed ranges with the gear selector
(5).
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.
Bosch Power Tools
Always push the gear selector switch as far as it will
u
go. Otherwise, the power tool may become damaged.
Adjusting the Speed
You can adjust the speed of the power tool when it is on by
pressing in the on/off switch (10) to varying extents.
A light pressure on the on/off switch (10) results in a low ro-
tational speed. Increased pressure on the switch causes an
increase in speed.
Switching on/off
To start the power tool, press and hold the on/off switch
(10).
The LED (11) lights up when the on/off switch (10) 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 (10).
Run-out brake
Upon releasing the on/off switch (10), 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 (10) once the screw has been inserted
flush into the workpiece. This way, the head of screw will not
penetrate the workpiece.
Fully automatic spindle lock (Auto-Lock)
The drill spindle, and therefore the tool holder (1), are
locked when the on/off switch (10) 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.
Battery Charge Indicator
When the on/off switch (10) is pressed in halfway or com-
pletely, the battery charge indicator (9) indicates the bat-
tery's state of charge 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 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.
