Take protective measures when dust can
develop during working that is harmful to
one's health, combustible or explosive. Ex-
ample: Some dusts are regarded as carcino-
genic. Wear a dust mask and work with dust /
chip extraction when connectable.
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
gripping surfaces when performing an op-
eration where the cutting tool may contact
hidden wiring or its own power cord. Con-
tact with a "live" wire will also make exposed
metal parts of the power tool "live" and shock
the operator.

Auxiliary Handle

Operate the machine only with the auxiliary
handle 6.
Loosen the handle by turning to the left. Rotate
the auxiliary handle 6 and adapt to the working
position.
Afterwards tighten the handle again by turn-
ing in clockwise direction.

Changing the Tool

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.
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. Let go of the locking
sleeve 2 again.
Starting Operation
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 5
and keep it depressed.
Lock the pushed On/Off switch 5 by pressing the
lock-on button 4.
To switch off the machine, release the On/Off
switch 5 or push and release it then.
At low temperatures, the machine reaches
full impact rate only after a certain time.
This start-up time can be shortened by
striking the chisel against the floor once.
