Noise/Vibration Information
Measured values determined according to
EN 60745.
Typically the A-weighted noise levels of the
product are: Sound pressure level 92 dB(A);
Sound power level 103 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
2
a =8 m/s , Uncertainty K=1.5 m/s
h
Disk sanding: Vibration emission value
2
a =3.5 m/s , Uncertainty K=1.5 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.

Assembly
Mounting the Protective Devices
Before any work on the machine itself, pull
the mains plug.
Note: After breakage of the grinding disc during
operation or damage to the holding fixtures on
the protection guard/power tool, the machine
must promptly be sent to an after-sales service
agent for maintenance (for addresses, see sec-
tion „After-sales Service and Customer
Assistance".
Protection Guard for Grinding
Place the protection guard 5 on the spindle col-
lar. Adjust the position of the protection guard 5
to the requirements of the operation and lock
the protection guard 5 with the locking screw 6.
Adjust the protection guard 5 in such a man-
ner that sparking is prevented in the direc-
tion of the operator.
Protection Guard for Cutting
For cutting metal, always work with the pro-
tection guard for cutting 7.
For cutting stone, always work with the cut-
ting guide with dust extraction protection
guard 20.
The protection guard for cutting 7 is mounted in
the same manner as the protection guard for
grinding 5.
