Battery Charging

A battery that is new or has not been used for a
longer period does not develop its full capacity
until after approx. 5 charging/discharging cycles.
To remove the battery 5 press the unlocking but-
tons 6 and pull out the battery downwards. Do
not exert any force.
The battery is equipped with a NTC temperature
control which allows charging only within a tem-
perature range of between 0 °C and 45 °C. A long
battery service life is achieved in this manner.
A significantly reduced working period after
charging indicates that the battery is used and
must be replaced.
Observe the notes for disposal.
Changing the Tool (see figure A)
Before any work on the machine (e. g., main-
tenance, tool change, etc.) as well as during
transport and storage, set the rotational di-
rection switch to the centre position. Unin-
tentional actuation of the On/Off switch can
lead to injuries.

Inserting
Pull the locking sleeve 2 forward, push the insert
tool to the stop into the tool holder 1 and release
the locking sleeve 2 to lock the insert tool.
For quick changing of bits, it is recommended to
use a universal bit holder 11.
Removing
Pull the locking sleeve 2 forward and remove the
insert tool.
GDS 12 V/GDS 14,4 V/GDS 18 V:
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.

Starting Operation

Inserting the Battery
Use only original Bosch O-pack batteries
with the voltage given on the type plate of
your machine. The use of other batteries can
lead to injuries and danger of fire.
Set the rotational direction switch 8 to the centre
position in order to avoid unintentional starting.
Insert the charged battery 5 into the handle so
that it can be felt to engage and faces flush
against the handle.
Reversing the Rotational Direction
(see figure B)
The rotational direction switch 8 is used to re-
verse the rotational direction of the machine.
However, this is not possible with the On/Off
switch 9 actuated.
Right rotation: For driving in screws and tighten-
ing nuts, press the rotational direction switch 8
through to the left stop.
Left Rotation: For loosening and unscrewing
screws and nuts, press the rotational direction
switch 8 through to the right stop.
Switching On and Off
To start the machine, press the On/Off switch 9
and keep it depressed.
To switch off the machine, release the On/Off
switch 9.
