Noise/Vibration Information
Measured values determined according to
EN 60745.
Typically the A-weighted noise levels of the
product are: Sound pressure level 91 dB(A);
Sound power level 102 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
h
=8.5 m/s
2
, Uncertainty K=1.5 m/s
2
,
Disk sanding: Vibration emission value
a
h
=3.0 m/s
2
, Uncertainty K=1.5 m/s
2
.
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.

Assembly
Mounting the Protective Devices
f
Before any work on the machine itself, pull
the mains plug.
Protection Guard for Grinding
Place the protection guard
11
onto the spindle collar
as shown in the illustra-
tion. The triangle marks on
the protection guard must
correspond with the re-
spective marks on the gear
case.
Press the protection guard
11
onto the spindle collar
until the shoulder of the
protection guard is seated
against the flange of the machine, and turn the
protection guard until it can clearly be heard to
engage.
Adjust the position of the protection guard
11
to
the requirements of the work process. For this,
press the release lever
1
upward and turn the
protection guard
11
to the required position.
f
Adjust the protection guard 11 in such a
manner that sparking is prevented in the di-
rection of the operator.
