Operation
Noise/vibration Information
Noise levels
Measured values determined according to
EN 60 745.
Typically the A-weighted noise levels of the
machine are:
sound pressure level (L
sound power level (L
wA
Measurement uncertainty K=3 dB
The noise level can exceed 85 dB(A)
during operation.
Wear ear protection!

The vibration emission 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 another.
The vibration emission level will vary because of
the ways in which a power tool can be used and
may increase above the level given in this infor-
mation sheet. This could lead to underestimation
of vibration when the tool is used regularly in such
a manner.
Note: To be accurate, an estimation of the level of
exposure to vibration experienced during a given
period of work should also take into account the
times when the tool is switched off and when it is
running but not actually when doing the job.

This may significantly 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 accessories, keep the hands
warm, organisation of work patterns.
4. Operation
Before carrying out any work on the
machine, pull the mains plug.
Putting into operation
Observe correct main voltage!
Before putting into operation, check that the mains
voltage and frequency on the identification plate
11,9
match the details of your mains supply.
Connect mains cable module if necessary

If the mains cable is damaged while
working, pull the mains plug immedi-
ately.
