Changing the Tool (see figure A)
Before any work on the machine (e. g.,
maintenance, tool change, etc.) as well as
during transport and storage, set the rota-
tional direction switch to the centre posi-
tion. Unintentional actuation of the On/Off
switch can lead to injuries.
GDR 14,4 V-LI/GDR 18 V-LI:
Inserting
Pull the locking sleeve 2 forward, push the in-
sert tool to the stop into the tool holder 1 and
release the locking sleeve 2 to lock the insert
tool.
Use only screwdriver bits with ball catch 10
(DIN 3126-E6.3). Other screwdriver bits 12 can
be used with a universal bit holder with ball
catch 11.
Removing
Pull the locking sleeve 2 forward and remove the
insert tool.
GDS 14,4 V-LI/GDS 18 V-LI:
When working with an application tool, pay
attention that the application tool is firmly
seated on the tool holder. When the applica-
tion tool is not firmly connected with the tool
holder, it can come loose again and not be
controlled.
Slide the application tool onto the square drive
of the tool holder 1.
Operation
Method of Operation
The tool holder 1 with the tool is driven by an
electric motor via a gear and impact mechanism.
The working procedure is divided into two phas-
es:
Screwing in and tightening (impact mechanism
in action).
The impact mechanism is activated as soon as
the screwed connection runs tight and thus load
is put on the motor. In this instance, the impact
mechanism converts the power of the motor to
steady rotary impacts. When loosening screws
or nuts, the process is reversed.
Bosch Power Tools
Starting Operation
Inserting the Battery
Use only original Bosch lithium ion batter-
ies with the voltage listed on the nameplate
of your power tool. Using other batteries can
lead to injuries and pose a fire hazard.
Set the rotational direction switch 7 to the cen-
tre position to protect the power tool against
accidental starting.
Insert the charged battery 5 from the front into
the base of the power tool until the battery is se-
curely locked.
Reversing the Rotational Direction
(see figure B)
The rotational direction switch 7 is used to re-
verse the rotational direction of the machine.
However, this is not possible with the On/Off
switch 8 actuated.
Right rotation: For driving in screws and tight-
ening nuts, press the rotational direction switch
7 through to the left stop.
Left Rotation: For loosening and unscrewing
screws and nuts, press the rotational direction
switch 7 through to the right stop.
Switching On and Off
To start the machine, press the On/Off switch 8
and keep it pressed.
The light 9 is lit when the On/Off switch 8 is
slightly or completely pressed in and permits to
light the work area when the lighting conditions
are bad.
To switch off the machine, release the On/Off
switch 8.
Adjusting the Speed
The speed of the switched on power tool can be
variably adjusted, depending on how far the
On/Off switch 8 is pressed.
Light pressure on the On/Off switch 8 results in
a low rotational speed. Further pressure on the
switch results in an increase in speed.
