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 8.
The auxiliary handle 8 can be set to any position
for a secure and low-fatigue working posture.
Turn the bottom part of the auxiliary handle 8 in
counterclockwise direction and swivel the auxil-
iary handle 8 to the desired position. Then re-
tighten the bottom part of the auxiliary handle 8
by turning in clockwise direction.
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 hav-
ing this carried out by an after-sales service.

Operation

Starting Operation

mode selector switch 4 to the required position.
