terface. Local operating restrictions, e.g. in aircraft or
hospitals, must be observed.
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 onto a diagram, the result is the
curve of a torque characteristic. The height of the curve cor-
responds to the maximum achievable torque, and the steep-
ness indicates the duration in which this is achieved.
A torque characteristic depends on the following factors:
– Strength properties of the screws/nuts
– Type of backing (washer, disc spring, seal)

Tips
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.
Note: Ensure that no metal particles enter the power tool.
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.
Recommendations for optimal handling of the battery
Protect the battery against moisture and water.
Only store the battery within a temperature range of -20 to
50 °C. Do not leave the battery in your car in the summer, for
example.
A significantly reduced operating time after charging indic-
ates that the battery has deteriorated and must be replaced.
Follow the instructions on correct disposal.
Ladder clip
You can use the utility clip (4) for hanging the power tool to a
ladder, for example.

– Strength properties of the material being screwed/bolted
together
– Lubrication conditions at the screw/bolt connection
Consequently, the following applies in each case:
– A hard seat is used for metal-to-metal screw applications
that use washers. After a relatively short impact duration,
the maximum torque is achieved (steep characteristic
curve). An unnecessarily long impact duration only
causes damage to the machine.
– A spring-loaded seat is used for metal-to-metal screw
applications that use spring washers, disc springs, studs
or screws/nuts with conical seats. It is also called a
spring-loaded seat when extensions are used.
– A soft seat is used for screw applications of e.g. metal on
wood or screw applications that use lead washers or fibre
washers as backing.
For a spring-loaded seat, as well as for a soft seat, the max-
imum tightening torque is lower than for a hard seat. A much
longer impact duration is also required.

Control Via App
GDS 18V-1000 C / GDS 18V-1000 PC /
GDS 18V-1050 HC:
The power tool can be fitted with a Bluetooth® module which
enables wireless data transfer to certain mobile devices with
a Bluetooth® interface (e.g. smartphone, tablet).
In order to control the power tool via Bluetooth®, you will
need the "Bosch Toolbox" app. Download the app from the
corresponding app store (Apple App Store, Google Play
Store).
Then select the "My Tools" sub-item in the app. The display
of your mobile terminal device will show you all subsequent
steps required to connect the power tool to the terminal
device.
The following functions will be available when a connection
has been established with the mobile device:

The screw of the ladder clip must be tightened
using a tightening torque of approx. 2.0–
2.5 Nm.
