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).
Do not look directly into the worklight; it can blind
u
you.
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).
Practical advice
Only apply the power tool to the screw/nut when the
u
tool is switched off. Rotating tool inserts can slip off.

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.
Screw applications with hard, spring-loaded or soft seats
When the achieved torques in an impact series are measured
during a test and transferred into a diagram, the result is the

steepness indicates the duration in which this is achieved.
A torque gradient depends on the following factors:
– Strength properties of the screws/nuts
– Type of backing (washer, disc spring, seal)
– Strength properties of the material being screwed/bolted
– Lubrication conditions at the screw/bolt connection
The following application cases result accordingly:
– A hard seat is a metal-to-metal screw application which
– A spring-loaded seat is also a metal-to-metal screw ap-
– A soft seat is a screw application of e.g. metal on wood or
For a spring-loaded seat as well as for a soft seat, the max-
imum tightening torque is lower than for a hard seat. Also, a
clearly longer impact duration is required.
