Assembly
Before any work on the machine itself, pull
the mains plug.
Auxiliary Handle
Operate your machine only with the auxilia-
ry handle 10.
The auxiliary handle 10 can be set to any posi-
tion for a secure and low-fatigue working pos-
ture.
– Turn the bottom part of the auxiliary handle
10 in counterclockwise direction and swivel
the auxiliary handle 10 to the desired posi-
tion. Then retighten the bottom part of the
auxiliary handle 10 by turning in clockwise di-
rection.
Changing the Tool
With the SDS-max tool holder, simpler and eas-
ier tool changing is possible without additional
aids.
The dust protection cap 1 largely prevents the
entry of drilling dust into the tool holder during
operation. When inserting the tool, take care
that the dust protection cap 1 is not damaged.
A damaged dust protection cap should be
changed immediately. We recommend hav-
ing this carried out by an after-sales serv-
ice.
Inserting (see figure A)
– Clean and lightly grease the shank end of the
tool.
The red symbols (open lock and bars) on the
locking sleeve 2 indicate that the tool holder is
open.
– Insert the tool into the tool holder with a
turning motion until it is automatically
locked. The locking sleeve automatically
snaps toward the front and the red ring is no
longer visible. This indicates that the tool
holder is locked.

Removing (see figure B)
– Pull the locking sleeve 2 back until it engag-
es. The red symbols on the locking sleeve can
now be seen again. The locking sleeve re-
mains in this position and the tool can be re-
moved without having to hold the locking
sleeve.
Dust/Chip Extraction
Dusts 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 dusts can cause allergic reac-
tions and/or lead to respiratory infections of the
user or bystanders.
Certain dusts, such as oak or beech dust, are
considered as carcinogenic, especially in con-
nection with wood-treatment additives (chro-
mate, 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 materials to be worked.
Operation
Starting Operation
Observe correct mains voltage! The voltage
of the power 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 select-
ed with the mode selector switch 3.
Note: Change the operating mode only when the
machine is switched off! Otherwise, the ma-
chine can be damaged.
– Turn the mode selector switch 3 to the re-
quested position.
