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 (16) to the middle posi-
tion to avoid unintentionally switching it on. Insert the
charged battery (11) into the handle until you feel it engage
and it is flush with the handle.
Setting the rotational direction (see figure B)
The rotational direction switch (16) is used to change the ro-
tational direction of the power tool. However, this is not pos-
sible while the on/off switch (17) is being pressed.
Rotate clockwise: Slide the rotational direction
switch (16) on both sides until it stops in the
tion.
Rotate anti-clockwise: Slide the rotational direction
switch (16) on both sides until it stops in the
tion.
Setting the operating mode
Drilling
Set the mode selector switch (7) to the
"drilling" symbol.
Screwdriving
Set the mode selector switch (7) to the "screw-
driving" symbol.
Impact drilling (GSB 18V-150 C)
Set the mode selector switch (7) to the "impact
drilling" symbol.
Switching on/off
To start the power tool, press and hold the on/off switch
(17).
The LED (13) lights up when the on/off switch (17) 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 (17).
Adjusting the Speed
You can adjust the speed of the power tool when it is on by
pressing in the on/off switch (17) to varying extents.
A light pressure on the on/off switch (17) results in a low ro-
tational speed. Increased pressure on the switch causes an
increase in speed.
Preselecting torque (applies to screwdriving mode)
The torque presetting ring (6) can be used to preselect the
required torque in 25 stages. Once the set torque has been
reached, the application tool will be stopped.
Mechanical gear selection
Only operate the gear selector (8) when the power
u
tool is not in use.
Bosch Power Tools
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.
Rapid Shut-off (KickBack Control)
The rapid shut-off function (KickBack Con-
trol) gives the user greater control over the
power tool and offers them better protec-
tion than power tools that do not have Kick-
Back Control. The power tool will switch off if it suddenly
and unforeseeably rotates around the drilling axis.
The rapid shut-off is indicated by the LED (22) flashing red,
a flashing light from the worklight (13) and the LED of the
posi-
KickBack Control (23) lighting up red on the power tool.
To switch the tool back on, release the on/off switch and
then press it again.
posi-
It will no longer be possible to switch the power tool
u
on if the KickBack Control function is faulty. Have the
power tool serviced by a qualified repair person using
only original replacement parts.
The rapid shut-off function can be deactivated on the user
interface (14) with the button (24). If the power tool is not
used for longer than 5 minutes or if the rechargeable battery
is removed, the rapid shut-off function automatically
switches back on. The current status is shown via the LED
for KickBack Control (23) on the user interface (14).
Please note that the warning light is not visible from all direc-
tions. The warning light is difficult to see in bright sunlight.
Electronic Angle Detection (EAD)
With electronic angle detection (EAD), a slope angle can be
preselected that the power tool detects during work and dis-
plays to the user. This means it is possible to drill or screw at
right angles in a sloped surface, for example. Electronic
angle detection (EAD) is controlled via the user
interface (14).
Select an angle (45°, 60°, user-defined) on the user
interface (14). Note: The user-defined angle in the factory
settings is 90°. This angle can be adjusted via the Bosch app.
To adjust the angle, press the button for the electronic angle
detection (EAD) (20) until the LED of the required slope
angle (21) starts flashing.
In addition to the LED of the required slope angle (21), the
LED of the electronic angle detection (EAD) (9) also starts to
flash yellow. Now position the power tool on the required
surface and hold it as still as possible. Note: If the power tool
is not held still during the initiating process, the initiating
process will automatically end after 10 seconds and the last
set value is restored.
The power tool will start the initiating process once it is posi-
tioned. The required surface is taught in during the initiating
process. The initiating process is complete when the LED of
the electronic angle detection (EAD) (9) lights up green for
