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 ca-
ble. Do not touch the damaged cable and
pull the mains plug when the cable is dam-
aged while working. Damaged cables in-
crease the risk of an electric shock.
Functional Description
Read all safety warnings and all in-
structions. Failure to follow the
warnings and instructions may re-
sult in electric shock, fire and/or se-
rious injury.
While reading the operating instructions, unfold
the graphics page for the machine and leave it
open.
Intended Use
The machine is intended for impact drilling in
brick, concrete and stone as well as for drilling
in wood, metal and plastic. Machines with elec-
tronic 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 levels of the
product are: Sound pressure level 96 dB(A);
Sound power level 107 dB(A). Uncertainty
K =3 dB.
Wear hearing protection!
Vibration total values (triax vector sum) deter-
mined according to EN 60745:
Drilling into metal: Vibration emission value

The vibration emission level given in this infor-
mation sheet has been measured in accordance
with a standardised test given in EN 60745 and
may be used to compare one tool with another.
It may be used for a preliminary assessment of
exposure.
The declared vibration emission level repre-
sents the main applications of the tool. However
if the tool is used for different applications, with
different accessories or poorly maintained, the
vibration emission may differ. This may signifi-
cantly increase the exposure level over the total
working period.
An estimation of the level of exposure to vibra-
tion should also take into account the times
when the tool is switched off or when it is run-
ning but not actually doing the job. This may sig-
nificantly reduce the exposure level over the to-
tal working period.
Identify additional safety measures to protect
the operator from the effects of vibration such
as: maintain the tool and the accessories, keep
the hands warm, organisation of work patterns.
