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.

Noise/Vibration Information
The measured values of the machine are listed in the table on
page 175.
Noise and vibrational values (vector sum of three directions)
determined according to EN 60745.
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
applications of the tool. However if the tool is used for differ-
ent applications, with different accessories or insertion
tools or is poorly maintained, the vibration emission may dif-
fer. This may significantly increase the exposure level over
the total working period.
An estimation of the level of exposure to vibration should al-
so take into account the times when the tool is switched off
or when it is running but not actually doing the job. This may
significantly reduce the exposure level over the total work-
ing 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.
