Delivery Scope
Rotary hammer, auxiliary handle and depth stop.
Application tools and other accessories shown or described
are not part of the standard delivery scope.
A complete overview of accessories can be found in our ac-
cessories program.
Intended Use
The machine is intended for hammer drilling in concrete,
bricks and masonry, as well as for light chiselling work. It is al-
so suitable for drilling without impact in wood, metal, ceram-
ics and plastic, as well as for screwdriving.
Technical Data
The technical data of the machine are listed in the Table on
page 128.
The values given are valid for a nominal voltage [U] of 230 V.
For different voltages and models for specific countries,
these values can vary.
Please observe the article number on the type plate of your
machine. The trade names of the individual machines may
vary.

Noise/Vibration Information
The measured values of the machine are listed in the table on
page 128.
Noise and vibrational values (vector sum of three directions)
determined according to EN 60745.
The vibration emission level given in this information 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 expo-
sure.
The declared vibration emission level represents the main ap-
plications 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 significantly in-
crease the exposure level over the total working period.
An estimation of the level of exposure to vibration should also
take into account the times when the tool is switched off or
when it is running but not actually doing the job. This may sig-
nificantly reduce the exposure level over the total working pe-
riod.
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 pat-
terns.
