Inserting the Application Tool
GDR 18V-215:
NOTE: Depending on the article number, only certain types
of bits can be used (see table below).
GDR 18V-215:

Single end bit
9.5 mm
Double end bit
9.8 mm
Pull the locking sleeve (2) forward, guide the application tool
(1) into the tool holder up to the stop and release the locking
sleeve (2) to lock the application tool.
Screwdriver bits (13) can be inserted using a universal bit
holder with ball catch (12).
GDX 18V-285:
Observe the information on the safe use of application
u
tools. Some application tools are not suitable for this
power tool due to the high torque.
When fitting an application tool, make sure that it is
u
held securely in the tool holder. If the application tool is
not held securely in the tool holder, it may become loose
and consequently uncontrollable.

of bits can be used (see table below).

Slide the application tool (14) onto the square drive of the
tool holder (1).
Due to the way the system operates, the application tool
(14) will move around slightly in the tool holder (1); this has
no influence on the function/safety.
Removing
Pull the locking sleeve (2) forward and remove the applica-
tion tool.
Belt clip
You can use the belt clip to hang the power tool on a belt, for
example. You then have both hands free and the power tool
is always at hand.
Operation
Only apply the power tool to the screw/nut when the
u
tool is switched off. Rotating tool inserts can slip off.

Operating Principle
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
3 601 JN2 0L0
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,
9.5 mm
the process is reversed.
14 mm
Set the rotational direction (see figure C)
9.8 mm
The rotational direction switch (4) is used to change the ro-
17 mm
tational direction of the power tool. However, this is not pos-
sible while the on/off switch (9) is being pressed.
Right rotation: To drive in screws and tighten nuts, press
the rotational direction switch (4) through to the left stop.
Left Rotation: To loosen and unscrew screws and nuts,
press the rotational direction switch (4) 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 (9) to varying ex-
tents.
Applying light pressure to the on/off switch (9) results in a
low rotational speed/impact rate. Applying increasing pres-
sure to the switch increases the speed/impact rate.
Switching on/off
3 601 JN2 1L0
To start the power tool, press and hold the on/off switch

(9).
9.5 mm
The worklight (3) lights up when the on/off switch (9) is
lightly or fully pressed, allowing the work area to be illumin-
14 mm
ated in poor lighting conditions.
9.8 mm
To switch off the power tool, release the on/off switch (9).
17 mm
The worklight (3) will remain lit for approx. 15 seconds after
the on/off switch (9) has been released.
Practical advice
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 joints
When the achieved torques in an impact series are measured
during a test and transferred into a diagram, the result is the
curve of a torque characteristic. The height of the curve cor-
responds with the maximum reachable torque, and the
steepness indicates the duration in which this is achieved.
A torque gradient depends on the following factors:
– Strength properties of the screws/nuts
