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 165.

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 165.

Sound emission values determined according to 
EN 60745-2-6.

Vibration total values a

h

 (triax vector sum) and uncertainty K 

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.
