Adjusting the Drilling Depth
The required drilling depth X can be set with the depth stop 3.
Loosen the wing bolt for the depth stop adjustment 6 and
insert the depth stop rod into the auxiliary handle 4.
Pull out the depth stop until the distance between the tip of the
drill bit and the tip of the depth stop corresponds with the
desired drilling depth X.
Retighten the wing bolt for the depth stop adjustment 6 again.
Changing the Tool (see figure A)
 Before any work on the machine itself (e. g.
maintenance, tool change, etc.) as well as dur-
ing transport and storage, remove the battery
from the power tool. There is danger of injury when
unintentionally actuating the On/Off switch.
Open the keyless chuck 2 by turning in rotation direction ,
until the tool can be inserted. Insert the tool.
Firmly tighten the collar of the keyless chuck 2 by hand in rota-
tion direction . This automatically locks the drill chuck.
Dust/Chip Extraction
Dust from materials such as lead-containing coat-
ings, some wood types, minerals and metal can
be harmful to one's health and cause allergic
reactions, lead to respiratory infections and/or
cancer. 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 mate-
rials to be worked.
 Prevent dust accumulation at the workplace.
Dust can easily ignite.

Starting Operation

Inserting the Battery
Note: Use of batteries not suitable for the machine can lead
to malfunctions of or cause damage to the power tool.
Set the rotational direction switch 16 to the centre position in
order to avoid unintentional starting. Insert the charged bat-
tery 11 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 16 is used to reverse the rota-
tional direction of the machine. However, this is not possible
with the On/Off switch 17 actuated.
Rotate clockwise: Move the rotational direction
switch 16 on both sides up to the stop into position
Rotate anticlockwise: Move the rotational direction
switch 16 on both sides up to the stop into position
Setting the Operating Mode
Drilling
Set the operating mode selector switch 8 to the
"drilling" symbol.
Screwdriving
Set the operating mode selector switch 8 to the
"screwdriving" symbol.
Impact drilling
(BS 18-A EC Power Combi)
Set the operating mode selector switch 8 to the
"impact drilling" symbol.
Switching On and Off
To start the machine, press the On/Off switch 17 and keep
it pressed.
The LED 14 lights up when the On/Off switch 17 is halfway
or fully pressed, and enables illumination of the screwing loca-
tion in unfavourable light conditions.
To save energy, only switch the power tool on when using it.
Adjusting the Speed
The speed of the switched-on power tool can be variably
adjusted, depending on how far the On/Off switch 17 is
pressed.
Light pressure on the On/Off switch 17 results in a low rota-
tional speed. Further pressure on the switch results in an
increase in speed.
Setting the torque
(Applies to Screwdriving Mode)
With the torque preselection ring 7, the required torque can
be preselected in 25 steps. The inserted tool is stopped as
soon as the set torque is reached.
