Noise/Vibration Information
Measured values determined according to
EN 60745.
Typically the A-weighted noise levels of the
product are: Sound pressure level 89 dB(A);
Sound power level 100 dB(A). Uncertainty
K=3dB.
Wear hearing protection!
Vibration total values (triax vector sum) deter-
mined according to EN 60745:
Surface grinding: Vibration emission value

,
Disk sanding: Vibration emission value

.
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 7 on the spindle col-
lar. Adjust the position of the protection guard 7
to the requirements of the operation and lock
the protection guard 7 with the locking screw 6.
f Adjust the protection guard 7 in such a man-
ner that sparking is prevented in the direc-
tion of the operator.
Note: The encoding keys on the protection
guard 7 ensure that only a protection guard that
fits the machine type can be mounted.
Protection Guard for Cutting
f For cutting metal, always work with the pro-
tection guard for cutting 12.
f For cutting stone, always work with the cut-
ting guide with dust extraction protection
guard 19.
The protection guard for cutting 12 is mounted
in the same manner as the protection guard for
sanding 7.
Auxiliary Handle
f Operate your machine only with the auxilia-
ry handle 4.
Screw the auxiliary handle 4 on the right or left
of the machine head depending on the working
method.
Vibration-dampening Auxiliary Handle
The vibration-dampening auxiliary handle reduc-
es the vibrations, making operation more com-
fortable and secure.
f Do not make any alterations to the auxiliary
handle.
Do not continue to use an auxiliary handle if it
is damaged.
