Set the rotational direction (see figure E)
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.

Speed preselection
With the speed preselection button (16), you can preselect
the required speed in three stages. Press button (16) as of-
ten as needed until the required setting is indicated in the
speed indicator (17). The selected setting will be saved.
GDS 18V-1000 C / GDS 18V-1050 HC:
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.

You can use the button for speed preselection (16) to
preselect the required speed, even during operation.
Switching On the Worklight
GDS 18V-1000 / GDS 18V-1050 H:
To switch the worklight (15) on or off, press the worklight
button (13).

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 (15) 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 figures D–E)
GDS 18V-1000 C / GDS 18V-1050 HC:
The user interface (7) is used to preselect the speed and
working mode and to indicate the status of the power tool.

Selecting the working mode
GDS 18V-1000 C / GDS 18V-1050 HC:
The power tool has two preset working modes A and B (12).
You can also programme working modes for different applic-
ations and adjust existing modes via the Bosch Toolbox un-
der A and B (12).
To switch between the working modes A and B (12), press
button (14).

The torque depends on the impact duration. The maximum
achieved torque results from the sum of all individual
torques achieved through impact. Maximum torque is
achieved after an impact duration of 6–10 seconds. After
this duration, the tightening torque increases only minimally.
The impact duration is to be determined for each required
tightening torque. The tightening torque actually achieved
should always be checked with a torque wrench.
Solution
–
Run the power tool at no load and allow it to
cool down, or replace or charge the battery
soon
Allow the power tool to cool down, or replace
or charge the battery
–
Do not look directly into the worklight; it can blind
you.
Only apply the power tool to the screw/nut when the
tool is switched off. Rotating tool inserts can slip off.
The power tool with inserted Bluetooth
Module GCY 42 (accessory) is equipped with a radio
interface. Local operating restrictions, e.g. in aircraft
or hospitals, must be observed.
