Read all instructions. Failure to
follow all instructions listed below
may result in electric shock, fire
and/or serious injury.
SAVE THESE INSTRUCTIONS.
■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
securely than by hand.
■Do not work materials containing asbes-
tos. Asbestos is considered carcinogenic.
■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.
■Do not use a machine with a damaged
mains cable. Do not touch the damaged ca-
ble and pull the mains plug when the cable
is damaged while working. Damaged cables
increase the risk of an electric shock.
■Connect machines that are used in the
open via a residual current device (RCD).
■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 util-
ity 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.
■Hold the power tool only by the insulated
handles, when performing an operation
where the tool insert can run into hidden
wiring or its own mains cable. Contact with
a “live”wire can make metal parts of the power
tool “live”and lead to an electric shock.
■Before any work on the machine itself, pull the
mains plug.
With the SDS-plus tool holder, simpler and easier
tool changing is possible without additional aids.
☞Grease the shank end of the tool regu-
larly.
The dust protection cap 1 largely prevents the
entry of drilling dust during operation. When in-
serting the tool, take care that the dust protection
cap 1 is not damaged.
A damaged dust protection cap should be
changed immediately. We recommend having
this carried out by an after-sales service.
☞As a requirement of the system, the
SDS-plus tool must rotate freely. At no-load
speed, this leads to a certain amount of ra-
dial run-out.
This does not affect the accuracy of the drill
hole, as the bit is automatically centred dur-
ing drilling.
Inserting (see figure )
Clean and grease the shank end of the tool.
Insert the tool in a twisting manner into the tool
holder until it locks. Check if it has locked by pull-
ing the tool.
Removing (see figure )
Push back the locking sleeve 2 of the tool holder
and remove the tool.

■Operate the machine only with the auxiliary
handle 7.
Loosen the handle by turning to the left. Rotate
the auxiliary handle 7 and adapt to the working
position.
Afterwards tighten the handle again by turning in
clockwise direction.
The drilling depth can be set with the depth
stop 8.
For this, loosen wing bolt for depth stop adjust-
ment 6, set the required drilling depth Xand
tighten the wing bolt again.
The ribbing on depth stop 8 must point upwards.
Observe correct mains voltage: The voltage of
the power source must agree with the voltage
specified on the nameplate of the machine.
Equipment marked with 230 V can also be con-
nected to 220 V.
Switching On and Off
To start the machine, press the On/Off switch 3
and keep it depressed.
To switch off the machine, release the On/Off
switch 3.
☞For low temperatures, the machine
reaches the full hammer/impact capacity
only after a certain time.
This start-up time can be shortened by
striking the drill/chisel against the floor one
time.
With the On/Off switch 3, the rotational speed/im-
pact rate can be regulated between low and high
speed/rate. Light pressure on the On/Off switch 3
results in a low rotational speed/impact rate, for
example, for sensitive work such as hole starting.
With increased pressure, the rotational speed/im-
pact rate is increased.
The electronic control enables continuous pre-se-
lection of speed and impact rate in accordance
with the material to be worked. Adjustment is car-
ried out with the speed selector thumbwheel 9.
The constant electronic control keeps the pre-se-
lected speed and impact rate nearly constant be-
tween no-load and load conditions.
The speed must be selected in accordance with
the material.
The values in the table are recommendations.

■Operate the mode selector switch 4 only
when the machine is at a standstill.
Press the release button 5 on the mode selector
switch 4 and turn the switch to the desired posi-
tion.
Drilling
Hammer drilling
Changing the Chiselling
Position (Vario-lock)
Chiselling (rotation off)
If the tool insert becomes caught or
jammed, the drive to the drill spindle is in-
terrupted.
Because of the forces that occur, always
hold the power tool firmly with both
hands and provide for a secure stance.
If the drilling tool jams, switch the machine off and
loosen the drilling tool. When switching the ma-
chine on with the drilling tool jammed, high reac-
tion torques can occur!
The chisel can be locked in 36 positions. In this
manner, the optimum working position can be set
for each application.
Insert the chisel in the tool holder.
Press the release button 5 and turn the mode se-
lector switch 4 at the same time to the “Chisel
(Vario-lock)”position.
Turn the tool holder to the desired chiselling posi-
tion.
Allow the mode selector switch 4 to latch in the
“Chiselling”position. The tool holder is locked in
this position.
The mode selector switch 4 must always be
locked in the “Chiselling”position when chis-
elling.
Removal (see figure )
Set the mode selector switch 4 temporarily to the
“Chiselling”position (drill spindle locked).
Turn the locking sleeve 2 firmly counter clock-
wise to the stop and pull off the tool holder.
Mounting
Place the tool holder on the drill spindle.
Turn the locking sleeve 2 counter clockwise (to
the left) and press back firmly at the same time
until the tool holder latches and locks itself. En-
sure that the tool holder is firmly seated.
