The lithium-ion battery can be charged at any time without
reducing its service life. Interrupting the charging process
does not damage the battery.
The lithium-ion battery is protected against deep discharge
by the "Electronic Cell Protection (ECP)". When the battery
is discharged, the power tool is switched off by means of a
protective circuit: The application tool no longer rotates.
Do not continue to press the On/Off switch after the
u
power tool has automatically switched off. The battery
can be damaged.
To remove the battery (5), press both release buttons (4)
and pull the battery downwards out of the power tool. Do
not use force to do this.
Follow the instructions on correct disposal.
Changing the tool
Inserting the application tool (see figure B)
Insert the application tool all the way into the mounting (1).
Fitting the adapter (see figure C)
Remove the application tool.
Insert the adapter into the holder (1). Turn the locking ring
(14) until it audibly engages.
Inserting the application tool into the adapter GFA 12-E,
GFA 12-X (see figure D)
Insert the application tool all the way into the mounting (1).
The application tool is held in the mounting by means of a
magnet.
GFA 12-B (see figure E)
Open the drill chuck adapter (11) by turning it in direction of
rotation ➊ until the application tool can be inserted. Insert
the application tool.
Firmly tighten the sleeve of the drill chuck adapter (11) by
turning it by hand in direction of rotation ➋. This will auto-
matically lock the drill chuck.
Turning the adapter (see figure F)
Pull the locked adapter approx. 5 mm away from the power
tool. Turn the adapter to the required position and then let it
go.
Removing the adapter (see figure G)
Remove the application tool.
Unlock the adapter in the direction and pull it off the
holder (1).
Dust/Chip Extraction
Dust from materials such as lead-containing coatings, some
wood types, minerals and metal can be harmful to one's
health. Touching or breathing-in the dust can cause allergic
reactions and/or lead to respiratory infections of the user or
bystanders.
Certain dust, such as oak or beech dust, is considered carci-
nogenic, especially in connection with wood-treatment ad-
ditives (chromate, wood preservative). Materials containing
asbestos may only be worked by specialists.

– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the ma-
terials to be worked.
Avoid dust accumulation at the workplace. Dust can
u
easily ignite.
Operation
Start-up
Inserting the battery
Note: The use of batteries unsuitable for your power tool can
lead to malfunctions or damage to the power tool.
Set the rotational direction switch (6) to the middle position
to avoid unintentionally switching it on. Insert the charged
battery (5) into the handle until you feel it engage and it is
flush with the handle.
Setting the rotational direction (see figure H)
Only operate the rotational direction switch (6) when
u
the power tool is not in use.
The rotational direction switch (6) is used to change the ro-
tational direction of the power tool. However, this is not pos-
sible while the on/off switch (7) is being pressed.
Right rotation: To drill and to drive in screws, press the ro-
tational direction switch (6) through to the left stop.
Left Rotation: To loosen and unscrew screws and nuts,
press the rotational direction switch (6) through to the right
stop.
Preselecting the Torque
The torque presetting ring (2) can be used to preselect the
required torque in 20 stages. When the correct setting is
used, the application tool will be stopped when the screw is
driven flush into the material or once the set torque has been
reached. In position the overload clutch is deactivated,
e.g. for drilling.
When unscrewing screws, you can select a higher setting or
set the tool to the symbol.
Mechanical gear selection
Only operate the gear selector (3) when the power
u
tool is not in use.
You can preselect two speed ranges with the gear selector
(3).
Gear I:
Low speed range; for screwdriving or working with a large
drilling diameter.
Gear II:
High speed range; for working with a small drilling diameter.
Switching on/off
To start the power tool, press and hold the on/off switch
(7).
The lamp (9) lights up when the on/off switch (7) is lightly or
fully pressed for a few seconds, meaning that the work area
is illuminated in poor lighting conditions.
