Intended Use

The machine is intended for hammer drilling in concrete,
brick and stone as well as for chiselling.

Technical Data

The technical data of the machine are listed in the table on
page 164.
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.

Noise/Vibration Information

The measured values of the machine are listed in the table on
page 164.
Sound emission values determined according to
EN 60745-2-6.
Vibration total values a (triax vector sum) and uncertainty K
h
determined according to EN 60745-2-6.

Mounting and Operation

The following table indicates the action objectives for mounting and operation of the power tool. The instructions for each action
objective are shown aside. Depending on the type of application, various instruction combinations are required. Observe the
safety instructions.

The vibration 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 anoth-
er. It may be used for a preliminary assessment of exposure.
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 insertion tools or is
poorly maintained, the vibration emission may differ. This
may significantly increase 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
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 pat-
terns.
