ating manual.
Intended Use
The power tool is intended for hammer drilling in concrete,
brick and stone, as well as for light chiselling work. It is also
suitable for drilling without impact in wood, metal, ceramic
and plastic. Power tools with electronic control and right/left
rotation are also suitable for screwdriving.

Noise/Vibration Information

Noise emission values determined according
to EN IEC 62841-2-6.
a)
Typically, the A-weighted noise level of the power tool is:
Sound pressure level 90 dB(A); sound power
level 101 dB(A). Uncertainty K = 3 dB.
Wear hearing protection!
Vibration total values a
determined according to EN IEC 62841-2-6:
Hammer drilling into concrete: a
Chiselling: a
The vibration level and noise emission value given in these
instructions have been measured in accordance with a
standardised measuring procedure and may be used to com-
pare power tools. They may also be used for a preliminary
estimation of vibration and noise emissions.
The stated vibration level and noise emission value repres-
ent the main applications of the power tool. However, if the
power tool is used for other applications, with different ap-
plication tools or is poorly maintained, the vibration level
a)
and noise emission value may differ. This may significantly
a)
increase the vibration and noise emissions over the total
working period.
To estimate vibration and noise emissions accurately, the
times when the tool is switched off or when it is running but
not actually being used should also be taken into account.
This may significantly reduce vibration and noise emissions
over the total working period.
