d) Store idle power tools out of the reach of
children and do not allow persons unfa-
miliar 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 misalign-
ment or binding of moving parts, break-
age 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. Prop-
erly 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 instruc-
tions, 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 quali-
fied repair person using only identical
replacement parts. This will ensure that the
safety of the power tool is maintained.
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 per-
sonal 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. Damaging a gas line can lead to explosion.
Penetrating a water line causes property damage
or may cause an electric shock.
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.
14 | English
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 carcino-
genic. Wear a dust mask and work with dust/chip
extraction when connectable.
Keep your workplace clean. Blends of materi-
als 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. Do not touch the damaged cable and
pull the mains plug when the cable is dam-
aged while working. Damaged cables increase
the risk of an electric shock.

Functional Description

Intended Use

The machine is intended for hammer drilling in con-
crete, brick and stone. 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 screwdriving and thread cutting.

Noise/Vibration Information

Measured values determined according to EN 60745.
Typically the A-weighted noise level of the machine is:
sound pressure level 90 dB(A); sound power level
101 dB(A). Uncertainty K=3 dB.
Wear hearing protection!
Overall vibrational value (vector sum of three direc-
tions) determined according to EN 60745:
