Drill Assistant
Applying the Drill Assistant (see figures C–D)
The Drill Assistant (10) can be used with and without the
dust collection device (13). Use of the dust collection
device (13) is limited to drill bits with a diameter of 12 mm
and a length of 120 mm.
Attach the dust collection device (13) to the adapter (26).
Press the unlocking button (8) to release the Drill
Assistant (10) from its parked position.
Guide the Drill Assistant (10) over the drill chuck onto the

Attach the drill bit (see section "Changing the Tool").
You can use the setting ring (17) to set the required drilling
depth X.
Unlock the setting ring (17) by turning it to the left
Place the dust container (11) or the adapter (26) flush
against the wall or workpiece. Move the tip of the drill bit to
the wall or workpiece.
Slide the setting ring (17) backwards until the distance
matches the required drilling depth X or place a wall plug on
the rail and slide the setting ring (17) backwards to the wall
plug. Lock the setting ring (17) by turning it to the right .
Take the wall plug out of the rail again. The drilling depth now
matches the set length X on the rail.
Note: It is important to have the exact drilling depth when
using wall plugs. If the drilled hole is too deep, the wall plug
will slip too far into the wall or workpiece. If the hole is too
small, the wall plug will stick out.
Emptying the dust container (see figure G)
The dust container (11) is enough for drilling about 25 holes
in masonry at a drilling depth of 30 mm with a drill bit dia-
meter of 6 mm.
To remove the dust container (11), press the side-mounted
unlocking buttons (12) and pull the dust container off down-

Dust Extraction/Dust Container
The dust from materials such as lead paint, some types of
wood, minerals and metal can be harmful to human health.
Touching or breathing in this dust can trigger allergic reac-
tions and/or cause respiratory illnesses in the user or in
people in the near vicinity.
Certain dusts, such as oak or beech dust, are classified as
carcinogenic, especially in conjunction with wood treatment
additives (chromate, wood preservative). Materials contain-
ing asbestos may only be machined by specialists.
– Use a dust extraction system that is suitable for the ma-
terial wherever possible.
– Provide good ventilation at the workplace.
– It is advisable to wear a P2 filter class breathing mask.
The regulations on the material being machined that apply in
the country of use must be observed.
Avoid dust accumulation at the workplace. Dust can
u
easily ignite.
Use the dust box only when working on concrete and
u
stone. Wood chips and plastic chips can easily lead to
clogging.
.
Warning: Danger of fire! Do not work on any metallic
u
materials with the dust container mounted. Hot metal
chips can ignite parts of the dust container.
Please observe the following instructions to optimise your
use of the dust container:
– Ensure that the dust container is placed flush against the
workpiece or wall. This also makes it easier to drill at a
right angle.
