Impact drilling
GSB 18V-50
Set the operating mode presetting ring (4) to
the "impact drilling" symbol.
Switching on/off
To start the power tool, press and hold the on/off switch
(11).
The LED (9) lights up when the on/off switch (11) 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 (11).
Adjusting the Speed
You can adjust the speed of the power tool when it is on by
pressing in the on/off switch (11) to varying extents.
A light pressure on the on/off switch (11) 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 (3) can be used to pre-select the
required torque in 20 stages. Once the set torque has been
reached, the application tool will be stopped.
Mechanical gear selection
Only operate the gear selector (5) when the power
u
tool is not in use.
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.
Temperature-dependent overload protection
When used as intended, the power tool cannot be over-
loaded. In the event of overloading or the temperature
rising/falling outside the permitted operating temperature
range, the speed will be reduced. The power tool will not run
at full speed again until the permitted operating temperature
has been reached.
Fully automatic spindle lock (Auto-Lock)
The drill spindle, and therefore the tool holder (1), are
locked when the on/off switch (11) is not pressed.
This enables screws to be screwed in even when the battery
(7) is empty and allows the power tool to be used as a
screwdriver.

Practical advice
Only apply the power tool to the screw when the tool
u
is switched off. Rotating application tools can slip off.
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.
An auxiliary tool can be used to remove the screwdriver bit
or universal bit holder.
Belt clip
You can use the belt clip (6) to hang the power tool on a belt,
for example. You then have both hands free and the power
tool is always at hand.
Maintenance and Service
Maintenance and Cleaning
Remove the battery from the power tool before carry-
u
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.
To ensure safe and efficient operation, always keep
u
the power tool and the ventilation slots clean.
