d) Store idle power tools out of the reach of
children and do not allow persons unfamiliar with the power tool or these
instructions to operate the power tool.
Power tools are dangerous in the hands of
untrained users.
e) Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that
may affect the power tool’s operation. If
damaged, have the power tool repaired
before use. Many accidents are caused by
poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting
edges are less likely to bind and are easier to
control.
g) Use the power tool, accessories and tool
bits etc. in accordance with these instructions, taking into account the working
conditions and the work to be performed.
Use of the power tool for operations different
from those intended could result in a hazardous
situation.
5) Service
a) Have your power tool serviced by a qualified repair person using only identical
replacement parts. This will ensure that the
safety of the power tool is maintained.
f When working with the machine, always
hold it firmly with both hands and provide for
a secure stance. The power tool is guided more
secure with both hands.
f Secure the workpiece. A workpiece clamped
with clamping devices or in a vice is held more
secure than by hand.
f Do not work materials containing asbestos.
Asbestos is considered carcinogenic.
f Take protective measures when dust can
develop during working that is harmful to
one’s health, combustible or explosive.
Example: Some dusts are regarded as carcinogenic. Wear a dust mask and work with dust/chip
extraction when connectable.
f Keep your workplace clean. Blends of materials are particularly dangerous. Dust from light
alloys can burn or explode.
f Always wait until the machine has come to a
complete stop before placing it down. The
tool insert can jam and lead to loss of control over
the power tool.
f Never use the machine with a damaged
cable. Do not touch the damaged cable and
pull the mains plug when the cable is damaged while working. Damaged cables increase
the risk of an electric shock.
Functional Description
Machine-specific
Safety Warnings
f Wear hearing protection. Exposure to noise
can cause hearing loss.
f Always use the auxiliary handle supplied
with the machine. Loss of control can cause personal injury.
f Use suitable detectors to determine if utility
lines are hidden in the work area or call the
local utility company for assistance. Contact
with electric lines can lead to fire and electric
shock. Damaging a gas line can lead to explosion.
Penetrating a water line causes property damage
or may cause an electric shock.
f Hold the power tool only by the insulated
gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its own power cord. Contact with
a “live” wire will also make exposed metal parts of
the power tool “live” and shock the operator.

Noise/Vibration Information
Measured values
EN 60745.
determined
according
to
Typically the A-weighted noise levels of the product
are: Sound pressure level 93 dB(A); Sound power
level 104 dB(A). Uncertainty K =2 dB.
Wear hearing protection!
Vibration total values (triax vector sum) determined
according to EN 60745:
Hammer drilling into concrete: Vibration emission
value ah =8 m/s2, Uncertainty K=1,5 m/s2,
Chiselling: Vibration emission value ah =7 m/s2,
Uncertainty K=1,5 m/s2.
WARNING The vibration emission 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 another.
The vibration emission level will vary because of the
ways in which a power tool can be used and may
increase above the level given in this information
sheet. This could lead to a significant underestimate
of exposure when the tool is used regularly in such a
way.
Note: To be accurate, an estimation of the level of
exposure to vibration experienced during a given
period of work should also take into account the times
when the tool is switched off and when it is running
but not actually doing the job. This may significantly
reduce the exposure level over the total working
period.

Assembly
f Before any work on the machine itself, pull
the mains plug.
Auxiliary Handle
f 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 counterclockwise 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.
Changing the Tool Holder
Dismounting the SDS-plus Tool Holder or the
Keyless Replacement 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 12
toward the front.
After removing, protect the tool holder 1 or the keyless
replacement chuck 12 against contamination. Lightly
lubricate the engaging grooves, if required.
Mounting the SDS-plus Tool Holder or the Keyless Replacement Chuck
Grasp the tool holder 1 or the keyless replacement
chuck 12 completely with your hand. Slide the tool
holder 1 or the keyless replacement chuck 12 with a
turning motion onto the drill chuck mounting until a
distinct latching noice is heard.
Press the button for the depth stop adjustment 9 and
insert the depth stop into the auxiliary handle 10.
The tool holder 1 or the keyless replacement chuck 12
is automatically locked. Check the locking effect by
pulling the tool holder.
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.
Changing the Tool
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
downward.
Selecting the Tool Holder
For hammer drilling, SDS-plus drilling tools that can
be inserted into the SDS-plus tool holder 1 are
required.
For drilling without impact in wood, metal, ceramic
and plastic 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 12.
With the SDS-plus tool holder, simple and convenient
tool changing is possible without additional aids.
As a requirement of the system, the SDS-plus drilling
tool can move freely. This causes a certain radial runout at no-load, which has no effect on the accuracy of
the drill hole, as the drill bit centres itself upon drilling.
The dust protection cap 2 largely prevents the entry of
drilling dust into the tool holder during operation.
When inserting the tool, take care that the dust protection cap 2 is not damaged.
f A damaged dust protection cap should be
changed immediately. We recommend having this carried out by an after-sales service.
Inserting SDS-plus Drilling Tools (see figure C)
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 SDS-plus Drilling Tools
(see figure D)
Push back the locking sleeve 3 and remove the tool.
Inserting Drilling Tools without SDS-plus
(see figure E)
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.
Insert the quick change keyless chuck 12.

the drilling location. The SDS-plus drilling tool must
face against the surface.
Position the the guide pipe 20 of the dust extraction
attachment in its holding fixture in such a manner that
the head of the dust extraction attachment faces
against the surface to be drilled. Do not slide the
guide pipe 20 further over the telescopic pipe 18 of
the dust extraction attachment than required, so that
as much as possible of the scale 18 on the telescopic
pipe remains visible.
Retighten the wing bolt 19 again. Loosen the clamping screw 16 on the depth stop of the dust extraction
attachment.
Move the depth stop 17 on the telescopic pipe 18 in
such a manner that the clearance X shown in the figure corresponds with the required drilling depth.
Tighten the clamping screw 16 in this position.
