Assembly
Before any work on the power tool itself,
pull the mains plug.

Auxiliary Handle

Operate your power tool only with the auxil-
iary handle 5.
The auxiliary handle 5 can be set to any position
for a secure and low-fatigue working posture.
Turn the bottom part of the auxiliary handle 5 in
counterclockwise direction and swivel the auxil-
iary handle 5 to the desired position. Then re-
tighten the bottom part of the auxiliary handle 5
by turning in clockwise direction.

Changing the Tool

The SDS-max/Hex drill chuck allows for simple
and convenient changing of drilling tools without
the use of additional tools.
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 service.
Inserting (see figure A)
Clean and lightly grease the shank end of the
tool.
Push back the locking sleeve 2 and insert the tool
in a twisting manner into the tool holder. Release
the locking sleeve 2 again in order to lock the
tool.
Check the latching by pulling the tool.
Removing (see figure B)
Push back the locking sleeve 2 and remove the
tool.

Operation

Starting Operation

Observe correct mains voltage! The voltage
of the power source must agree with the
voltage specified on the type plate of the
power tool.
Setting the Operating Mode
The operating mode of the power tool is selected
with the mode selector switch 3.
Note: Change the operating mode only when the
machine is switched off! Otherwise, the machine
can be damaged.
Turn the mode selector switch 3 to the requested
position.
Position for hammer drilling in
concrete or stone
When the drilling tool does not im-
mediately rotate upon switching
on, allow the machine to run slowly
until the drilling tool rotates.

Switching On and Off
To start the power tool, press the On/Off switch
4 and keep it pressed.
To switch off the power tool, release the On/Off
switch 4.
For low temperatures, the power tool reaches
the full hammer/impact capacity only after a cer-
tain time.
This start-up time can be shortened by striking
the inserted tool insert against the floor one
time.
