MACHINE SPECIFIC SAFETY WARNING
4
1) Machine Specific Safety Warnings
Wear hearing protection. Exposure to noise can
cause hearing loss.
Always use the auxiliary handle supplied with the
machine. Loss of control can cause personal
injury.
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. Dama-
ging a gas line can lead to explosion. Penetrating
a water line causes property damage or may
cause an electric shock.
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
cord. Contact with a “live” wire will also make
exposed metal parts of the power tool “live” and
shock the operator.
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.
Secure the workpiece. A workpiece clamped with
clamping devices or in a vice is held more secure
than by hand.
Do not work materials containing asbestos.
Asbestos is considered carcinogenic.
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.
Keep your workplace clean. Blends of materials
are particularly dangerous. Dust from light alloys
can burn or explode.
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.
Never use the machine with a damaged cable
and pull the mains plug when the cable is
damaged while
working. Damaged cables increase the risk of an
electric shock.
2) Functional Description
Read all safety warnings and all instructions.
Failure to follow the warnings and instructions
may result in electric shock, fire and/or serious
injury.
While reading the operating instructions, unfold
the graphics page for the machine and leave it
open.
a) Intended Use
The machine is intended for hammer drilling in
concrete, brick steel and wood. It is also suitable
for drilling without impact in wood, metal, ceramic
and plastic. Machines with electronic control and
right/left rotation are also suitable for screw
driving and thread cutting.

a) Auxiliary Handle
Operate your machine only with the auxiliary
handle 11.

OPERATION INSTRUCTION
5
Rotating the Auxiliary Handle, the auxiliary handle
11 can be set to any position for a secure and
low-fatigue working posture.
Turn the bottom part of the auxiliary handle 11 in
counterclockwise direction and swivel the
auxiliary handle 11 to the desired position. Then
retighten the bottom part of the auxiliary handle
11 by turning in clockwise direction.
Pay attention that the clamping band of the
auxiliary handle is positioned in the groove on the
housing as intended for.
b) Changing the Tool
The dust protection cap 3 largely prevents the
entry of drilling dust into the tool holder during
operation. When inserting the tool, take care that
the dust protection cap 3 is not damaged.
A damaged dust protection cap should be
changed immediately. We recommend having
carried out by an after-sales service.
Inserting SDS-plus Drilling Tools, the SDS drill
chuck allows for simple and convenient changing
of drilling tools without the use of additional tools.
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.
As a requirement of the system, the SDS drilling
tool can move freely. This causes a certain radial
run-out at no-load, which has no effect on the
accuracy of the drill hole, as the drill bit centre
itself upon drilling.
Removing SDS Drilling Tools, push back the
locking sleeve 4 and remove the tool.
4) Operation
1. Starting Operation
Observe correct mains voltage! The Voltage of
the power source must agree with the voltage
specified on the nameplate of the machine.
Setting the Operating mode, with the selector
switch for drilling/ hammer drilling 9, the operating
mode of the machine is selected. To change the
operating mode, press the release button 8 and
turn the drilling/ hammer drilling selector switch 9
to the desired position until can be heard to latch.
Note: only change the mode of operation while
disconnected from the machine! Otherwise you
may damage the machine.
Position for hammer drilling in concrete (fig.12).
Position for drilling without impact in wood, metal,
ceramic and plastic as well as for screw driving
and thread cutting. (fig.14).
Reversing the rotational direction, the rotational
direction switch 5 is used to reverse the rotational
direction of the machine. However, this is not
possible with the On/Off switch 7 actuated.
Right rotation: turn the selector switch for
drilling/hammer drilling 5 on both sides to the stop
in the position.
Left rotation: turn the selector switch for
drilling/hammer drilling 5 on both sides to the stop
in the position.
Set the direction of rotation for hammer drilling,
drilling and chiseling always to right rotation.
Switching On and Off, to start the machine, press
the On/Off switch, keep it pressed and additiona-
lly push the lock-on button 6. To switch off the
machine, release the On/Off switch 7.
When the On/Off switch 7 is locked, press it first
and then release it.
Setting the Speed/ Impact Rate, the speed/impact
rate of the switched on power tool can be variably
adjusted, depending on how far the On/Off switch
7/10 is pressed.
Light pressure on the On/Off switch 7/10 results
in low speed/impact rate. Further pressure on the
switch increases the speed/ impact rate.

OPERATION INSTRUCTION
Safety Clutch
If the tool insert becomes caught or jammed, the
drive to the drill spindle is interrupted. Because of
the forces that occur, always hold the power tools
firmly with both hands and provide for a secure
stance.
If the power tool jams, switch the machine off and
loosen the tool insert. When switching the
machine on with the drilling tool jammed, high
reaction torques can occur.
Switching On/Off: A
To start the machine, press the On/Off switch 6
and keep it depressed. To switch off the machine,
release the On/Off switch 6.
Setting the Speed/Impact Rate
The electronic control 10 enables stepless speed
and impact pre-selection in accordance with the
material to be worked.
The maximum hammering capacity is achieved
when the thumbwheel 10 is set to position “6”.
5) Maintenance and Service
a. Maintenance and Cleaning
Before any work on the machine itself, pull the
mains plug.
For safe and proper working, always keep the
machine and ventilation slots clean.
A damaged dust protection cap should be
changed immediately. We recommend having this
carried out by an after-sales service.
Clean the tool holder 2 each time after using.
Important:
When the carbon brushes wear below acceptable
service tolerances, the machine will automatically
cut out. The machine must be sent to customer
service for maintenance.
If the machine should fail despite the care taken
in manufacturing and testing procedures, repair
should be carried out by an after-sales service
centre for power tools.
In all correspondence and spare parts order,
please always include the article number given on
the type plate of the machine.
b. Disposal
We recommend subjecting electric tools,
accessories and packaging to a recovery process
that respect the environment.
Do not throw away electric tools!
Subject to change without notice.
