Intended Use
The machine is intended for cutting, roughing
and brushing of metal and stone materials with-
out the use of water.
For cutting with bonded abrasives, a special cut-
ting guide (accessory) must be used.
When cutting in stone, provide for sufficient
dust extraction.
With approved sanding tools, the machine can
be used for sanding with sanding discs.

Noise/Vibration Information
Measured sound values determined according
to EN 60745.
Typically the A-weighted noise levels of the
product are: Sound pressure level 86 dB(A);
Sound power level 97 dB(A). Uncertainty
K =3 dB.
Wear hearing protection!
Vibration total values (triax vector sum) deter-
mined according to EN 60745:
Surface grinding: Vibration emission value
a =7.0 m/s
h
Disk sanding: Vibration emission value
a =4.0 m/s
h
The vibration emission level given in this infor-
mation 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.
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.
