Removing Drilling Tools without SDS-plus
– Turn the sleeve of the key type drill chuck
14
with the drill
chuck key in anticlockwise direction until the drilling tool
can be removed.
Dust Extraction with the Dust Extraction Attach-
ment (Accessory)
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 car-
cinogenic, especially in connection with wood-treatment
additives (chromate, wood preservative). Materials con-
taining asbestos may only be worked by specialists.
– As far as possible, use a dust extraction system suitable
for the material.
– 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
materials to be worked.
Prevent dust accumulation at the workplace.
Dust can
easily ignite.
Mounting the Dust Extraction Attachment (see figure F)
For dust extraction, the dust extraction attachment (accesso-
ry) is required. When drilling, the dust extraction attachment
retracts so that the attachment head is always close to the
surface at the drill hole.
– Press the button for depth stop adjustment
10
and remove
the depth stop
11
. Press button
10
again and insert the
dust extraction attachment into the auxiliary handle
12
from the front.
– Connect an extraction hose (diameter 19 mm, accessory)
to the extraction sleeve
16
of the dust extraction attach-
ment.
The vacuum cleaner must be suitable for the material being
worked.
When vacuuming dry dust that is especially detrimental to
health or carcinogenic, use a special vacuum cleaner.
Adjusting the Drilling Depth on the Dust Extraction At-
tachment (see figure G)
The required drilling depth
X
can also be adjusted when the
dust extraction attachment is mounted.
– Insert the SDS-plus drilling tool to the stop into the SDS-
plus tool holder
1
. Otherwise, the movability of the SDS-
plus drilling tool can lead to incorrect adjustment of the
drilling depth.
– Loosen the wing bolt
20
on the dust extraction attach-
ment.
– Without switching the power tool on, apply it firmly to the
drilling location. The SDS-plus drilling tool must face
against the surface.
– Position the the guide pipe
21
of the dust extraction at-
tachment in its holding fixture in such a manner that the
head of the dust extraction attachment faces against the
surface to be drilled. Do not slide the guide pipe
21
further
over the telescopic pipe
19
of the dust extraction attach-
ment than required, so that as much as possible of the
scale
19
on the telescopic pipe remains visible.
– Retighten the wing bolt
20
again. Loosen the clamping
screw
17
on the depth stop of the dust extraction attach-
ment.
– Move the depth stop
18
on the telescopic pipe
19
in such
a manner that the clearance
X
shown in the figure corre-
sponds with the required drilling depth.
– Tighten the clamping screw
17
in this position.
Operation
Starting Operation
Observe correct mains voltage! The voltage of the pow-
er source must agree with the voltage specified on the
nameplate of the machine. Power tools marked with
230 V can also be operated with 220 V.
Setting the operating mode
The operating mode of the power tool is selected with the
mode selector switch
9
.
Note:
Change the operating mode only when the machine is
switched off! Otherwise, the machine can be damaged.
– To change the operating mode, push the release button
8
and turn the mode selector switch
9
to the requested posi-
tion until it can be heard to latch.
Reversing the rotational direction
The rotational direction switch
4
is used to reverse the rota-
tional direction of the machine. However, this is not possible
with the On/Off switch
6
actuated.
Right rotation:
Turn the selector switch for drilling/
hammer drilling
4
on both sides to the stop in the position
.
