Changing the Tool
With the SDS-max tool holder, simpler and easier 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 having
this carried out by an after-sales service.
Inserting (see figure A)
Clean and lightly grease the shank end of the tool.
Insert the tool in a twisting manner into the tool holder
until it latches itself.
Check the latching by pulling the tool.
Removing (see figure B)
Push back the locking sleeve 2 and remove the tool.
Dust/Chip Extraction
Dusts from materials such as lead-containing coat-
ings, some wood types, minerals and metal can be
harmful to one's health. Touching or breathing-in the
dusts can cause allergic reactions and/or lead to
respiratory infections of the user or bystanders.
Certain dusts, such as oak or beech dust, are con-
sidered as carcinogenic, especially in connection
with wood-treatment additives (chromate, 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 res-
pirator.
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 selected with
the mode selector switch 4.
Note: Change the operating mode only when the
machine is switched off! Otherwise, the machine can
be damaged.
Press and hold the unlocking button 3 and turn the
mode selector switch 4 to the required position.
Position for hammer drilling
When the drilling tool does not imme-
diately rotate upon switching on,
allow the machine to run slowly until
the drilling tool rotates.

Switching On and Off
To start the machine, press the On/Off switch 5 and
keep it pressed.
To switch off the machine, release the On/Off switch
5.
For low temperatures, the machine reaches the full
hammer/impact capacity only after a certain time.
This start-up time can be shortened by striking the
inserted tool insert against the floor one time.
Setting the Speed/Impact Rate
The electronic control enables stepless speed and
impact preselection in accordance with the material to
be worked.
The constant electronic control keeps the preselected
speed and impact rate nearly constant between no-
load and load conditions.
The maximum hammering capacity is achieved when
the thumbwheel 6 is set to position "6". For lower
speed settings, the hammering capacity is lower due to
technical reasons.
Select the speed with the thumbwheel 6 according to
the material.
The data in the following table are recommended val-
ues.
