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.
The light of this power tool is intended to illuminate the power
tool's direct area of working operation and is not suitable for
household room illumination.
Technical Data
The technical data of the machine are listed in the table on
page 197.
Noise/Vibration Information
The measured values of the machine are listed in the table on
page 197.
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.
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.
