Auxiliary Handle
Operate your machine only with the auxiliary
handle 7.
The auxiliary handle 7 can be set to any position for a
secure and low-fatigue working posture.
Loosen the knurled nut 8, rotate the auxiliary handle 7
around the axis of the machine to the required position
and tighten the knurled nut 8 again.
The auxiliary handle 7 can be mounted to a different
position. For this, completely unscrew the knurled nut
8 and then pull out the hexagon bolt upward. Pull off
the auxiliary handle 7 to the side and turn around the
remaining clamping element by 180°. Mount the aux-
iliary handle 7 in reverse order.
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 pro-
tection 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.
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.
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 accord-
ing to the material.
The data in the following table are recommended val-
ues.

Changing the Chiselling Position (Vario-Lock)
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 adjust-
ment ring 3.
Release the chisel adjustment ring 3 and turn the
chisel until it latches.
