tool holder. When the application tool is not securely
connected with the tool holder, it can come off during ap-
plication.
Slide the application tool (10) onto the square drive of the
tool holder (1).
Removing the Application Tool (see figure B)
GDS 18V-450 PC:
A pin secures application tools in the tool holder to ensure
they do not accidentally come loose.
To remove the application tool, push in the pin with an ap-
propriate auxiliary tool.
Operation
Method of Operation
The tool holder (1) (with the application tool) is driven by an
electric motor via a gear and impact mechanism.
The working procedure is divided into two phases:
Screwing in and tightening (impact mechanism in action).
The impact mechanism is activated as soon as the screwed
connection runs tight and load is therefore put on the motor.
The impact mechanism then converts the power of the mo-
tor to steady rotary impacts. When loosening screws or nuts,
the process is reversed.
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.

Speed preselection
With the speed preselection button (15), you can preselect
the required speed in three stages. Press button (15) as of-
ten as needed until the required setting is indicated in the
speed indicator (16). The selected setting will be saved.
You can also preselect the speed using the Bosch Toolbox
app.
The required speed depends on the material and the work-
ing conditions; it can be ascertained through practical tests.
The information in the table below describes the recommen-
ded values.

Push the charged battery (5) into the base of the power tool
until the battery is securely locked.
Set the rotational direction (see figure D)
The rotational direction switch (2) is used to change the ro-
tational direction of the power tool. However, this is not pos-
sible while the on/off switch (8) is being pressed.
Right rotation: To drive in screws and tighten nuts, press
the rotational direction switch (2) through to the left stop.
Left Rotation: To loosen and unscrew screws and nuts,
press the rotational direction switch (2) through to the right
stop.
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 (8) to varying ex-
tents.
Applying light pressure to the on/off switch (8) results in a
low rotational speed/impact rate. Applying increasing pres-
sure to the switch increases the speed/impact rate.
Switching on/off
To start the power tool, press and hold the on/off switch
(8).
The worklight (14) lights up when the on/off switch (8) is
lightly or fully pressed, allowing the work area to be illumin-
ated in poor lighting conditions.
To switch off the power tool, release the on/off switch (8).
User interface (see figure C)
The user interface (7) is used to preselect the speed and
working mode and to indicate the status of the power tool.
