Changing the Tool (see figures A–B)
u
Remove the battery from the power tool before carry-
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.
u
When working with an application tool, pay attention
that the application tool is connected securely to the
tool holder.
When the application tool is not securely
connected with the tool holder, it can come off during ap-
plication.
Slide the application tool
(10)
onto the square drive of the
tool holder
(1)
.
Operation
Method of Operation
The tool holder
(1)
(with the application tool) is driven by an
electric motor via a gear and impact mechanism.
The working procedure is divided into two phases:
Screwing in
and
tightening
(impact mechanism in action).
The impact mechanism is activated as soon as the screwed
connection runs tight and load is therefore put on the motor.
The impact mechanism then converts the power of the mo-
tor to steady rotary impacts. When loosening screws or nuts,
the process is reversed.
Starting Operation
u
Always place the power tool down on its side and do
not lay it on the battery.
The power tool can tip over de-
pending on the application tool and battery used.
Inserting the battery
Note:
The use of batteries unsuitable for your power tool can
lead to malfunctions or damage to the power tool.
Push the charged battery
(5)
into the base of the power tool
until the battery is securely locked.
Set the rotational direction (see figure E)
The rotational direction switch
(2)
is used to change the ro-
tational direction of the power tool. However, this is not pos-
sible while the on/off switch
(8)
is being pressed.
Right rotation:
To drive in screws and tighten nuts, press
the rotational direction switch
(2)
through to the left stop.
Left Rotation:
To loosen and unscrew screws and nuts,
press the rotational direction switch
(2)
through to the right
stop.
Adjusting the Speed/Impact Rate
You can adjust the speed/impact rate of the power tool when
it is on by pressing in the on/off switch
(8)
to varying ex-
tents.
Applying light pressure to the on/off switch
(8)
results in a
low rotational speed/impact rate. Applying increasing pres-
sure to the switch increases the speed/impact rate.
Switching on/off
To
start
the power tool, press and hold the on/off switch
(8)
.
The worklight
(15)
lights up when the on/off switch
(8)
is
lightly or fully pressed, allowing the work area to be illumin-
ated in poor lighting conditions.
To
switch off
the power tool, release the on/off switch
(8)
.
User interface (see figures D–E)
GDS 18V-1000 C / GDS 18V-1050 HC:
The user interface
(7)
is used to preselect the speed and
working mode and to indicate the status of the power tool.
