Noise/Vibration Information

Sound emission values determined according to
EN 60745-2-3.
Typically the A-weighted noise levels of the product are:
Sound pressure level 93 dB(A); Sound power level
104 dB(A). Uncertainty K =3 dB.
Wear hearing protection!
Vibration total values a (triax vector sum) and uncertainty K
h
determined according to EN 60745-2-3:
2
Surface grinding: a =7.5 m/s , K=1.5 m/s
h
2
Disk sanding: a =7.5 m/s , K=1.5 m/s
h
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.

press the release lever 7 upward and turn the protection
guard 8 to the required position.
 Always position the protective guard 8 such that both
cams on the unlocking lever 7 engage in the corre-
sponding openings on the guard 8.
 Adjust the protection guard 8 in such a manner that
sparking is prevented in the direction of the operator.
 The protection guard 8 may be turned only upon actua-
tion of the release lever 7! Otherwise the power tool
may not continue to be used under any circumstances
and must be taken to an after-sales service agent.
Note: The encoding keys on the protection guard 8 ensure
that only a protection guard that fits the machine type can be
mounted.
