Changing the Tool
❏ Before any work on the machine itself,
pull the mains plug.
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 pro-
tection 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 pre-
servative). 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 respi-
rator.
Observe the relevant regulations in your country for
the materials to be worked.
25.1.10
Starting Operation
❏ Observe correct mains voltage! The volt-
age 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.
Switching On and Off
To start the machine, push the On/Off switch 4 to
the right.
To switch off the machine, push the On/Off switch
4 to the left.
For low temperatures, the machine reaches the full
impact rate only after a certain time.
This start-up time can be shortened by striking the
chisel in the machine against the floor one time.
Setting the Impact Rate
The electronic control enables stepless speed prese-
lection in accordance with the material to be
worked.
The constant electronic control keeps the preselected
impact rate nearly constant between no-load and
load conditions.
Select the impact rate with the thumbwheel 5
according to the material.
The data in the following table are recommended
values.
Thumbwheel Position 5 Impact Rate (min
1 1030
2 1180
3 1360
4 1540
5 1720
6 1900
Changing the position of the chisel
The chisel can be locked in 12 positions. In this man-
ner, the optimum working position can be set for
each application.
Insert the chisel into the tool holder.
Push the chisel adjustment ring 3 forward and turn
the chisel to the required position with the chisel
adjustment ring 3.
Release the chisel adjustment ring 3 and turn the
chisel until it latches.
