Notes on the Power Supply
The power tool is part of a high-frequency sys-
tem and requires three-phase current with a fre-
quency according to the type plate.
To reach this frequency, the power tool must be
connected with a frequency converter (see
"Connection to the Power Supply", page 41).
Noise/Vibration Information
Measured values determined according to
EN 60745.
The vibration emission level given in this informa-
tion sheet has been measured in accordance with
a standardised test given in EN 60745 and may be
used to compare one tool with another. It may be
used for a preliminary assessment of exposure.
Typically the A-weighted sound
pressure level of the product is
Uncertainty K=
The noise level when working can
exceed 80 dB(A).
Wear hearing protection!
Overall vibrational values (vector
sum of three directions) determined
according to EN 60745:

Bosch Power Tools
The declared vibration emission level repre-
sents the main applications of the tool. However
if the tool is used for different applications, with
different accessories or poorly maintained, the
vibration emission may differ. This may signifi-
cantly increase the exposure level over the total
working period.
An estimation of the level of exposure to vibra-
tion should also take into account the times
when the tool is switched off or when it is run-
ning but not actually doing the job. This may sig-
nificantly reduce the exposure level over the to-
tal 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 patterns.
