The vibration level given in this information sheet has been
measured in accordance with a standardised test given in
EN 60745 and may be used to compare one tool with anoth-
er. It may be used for a preliminary assessment of exposure.
The declared vibration emission level represents the main ap-
plications of the tool. However if the tool is used for different
applications, with different accessories or insertion tools or is
poorly maintained, the vibration emission may differ. This
may significantly increase the exposure level over the total
working period.
An estimation of the level of exposure to vibration should also
take into account the times when the tool is switched off or
when it is running but not actually doing the job. This may sig-
nificantly reduce the exposure level over the total working
period.
Identify additional safety measures to protect the operator
from the effects of vibration such as: maintain the tool and the
accessories, keep the hands warm, organisation of work pat-
terns.
Declaration of Conformity
We declare under our sole responsibility that the product de-
scribed under “Technical Data” is in conformity with the fol-
lowing standards or standardization documents: EN 60745
according to the provisions of the directives 2011/65/EU,
2004/108/EC, 2006/42/EC.

Assembly
Before any work on the machine itself, pull the mains
plug.
Auxiliary Handle
Operate your machine only with the auxiliary handle
10.
The auxiliary handle 10 can be set to any position for a secure
and low-fatigue working posture.
Turn the bottom part of the auxiliary handle 10 in counter-
clockwise direction and swivel the auxiliary handle 10 to
the desired position. Then retighten the bottom part of the
auxiliary handle 10 by turning in clockwise direction.
Adjusting the Drilling Depth (see figure A)
The required drilling depth X can be set with the depth stop
11.
Press the button for the depth stop adjustment 9 and in-
sert the depth stop into the auxiliary handle 10.
Insert the SDS-plus drilling tool to the stop into the SDS-
plus tool holder 1. Otherwise, the movability of the SDS-
plus drilling tool can lead to incorrect adjustment of the
drilling depth.
Pull out the depth stop until the distance between the tip of
the drill bit and the tip of the depth stop correspond with
the desired drilling depth X.
The knurled surface of the depth stop 11 must face down-
ward.
Selecting the Tool Holder
For hammer drilling, SDS-plus drilling tools that can be insert-
ed into the SDS-plus tool holder 1 are required.
For drilling without impact in wood, metal, ceramic and plas-
tic as well as for screwdriving and tapping, use non-SDS-plus
drilling tools (e. g., drill bits with cylindrical shank). A keyless
drill chuck is required for such drilling tools.
Note: Do not use tools without SDS-plus for hammer drilling
or chiselling! Tools without SDS-plus and their drill chucks are
damaged by hammer drilling or chiselling.
The SDS-plus tool holder 1 can easily be exchanged against
the quick change keyless chuck 13.
Changing the Tool Holder
Dismounting the SDS-plus Tool Holder or the Quick
change keyless chuck (see figure B)
Pull the lock ring of the tool holder 4 firmly in the direction
of the arrow, hold it in this position and pull off the tool
holder 1 or the keyless replacement chuck 13 toward the
front.
After removing, protect the tool holder 1 or the quick change
keyless chuck 13 against contamination. Lightly lubricate the
engaging grooves, if required.
Mounting the SDS-plus Tool Holder or the Quick change
keyless chuck (see figure B)
Use only model-specific original equipment and pay at-
tention to the number of identification grooves .Only
quick-change chucks with two identification grooves
are permitted. When an unsuitable quick-change chuck is
used, the application tool could fall out during operation.
Grasp the tool holder 1 or the keyless replacement chuck
13 completely with your hand. Slide the tool holder 1 or
the keyless replacement chuck 13 with a turning motion
onto the drill chuck mounting until a distinct latching noice
is heard.
