Noise/Vibration Information

Sound emission values determined according to EN 60745-2-22.
Typically the A-weighted noise levels of the product are
Sound pressure level
Sound power level
Uncertainty K
Wear hearing protection!
Vibration total values a (triax vector sum) and uncertainty K

determined according to EN 60745-2-22:
Grinding surfaces (roughing):

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.

General Information
 Disconnect the power supply before making any ad-
justments, changing accessories, or placing the ma-
chine aside. This safety measure prevents accidental
starting of the power tool.
 Use only diamond-tipped cutting discs. Segmented dia-
mond wheels may only have negative cutting angles
and slots between the segments to a maximum of
10 mm.
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 ser-
vice agent for maintenance. For addresses, see section "Af-
ter-sales Service and Application Service".
 Adjust protection guards in such a manner that spark-
ing toward the operator is prevented.
Note: The encoding keys of the protection guards ensure that
only a protection guard that fits the machine type can be
mounted.
Protection Guard for Cutting (see figure A)
 For cutting with bonded abrasives, always use a pro-
tection guard for cutting.
 For cutting stone, always use a cutting guide with dust
extraction protection guard (accessory).
– Release the clamping lever 9.
– Place the protection guard 6 with the encoding key 8 in the
encoding slot on the spindle collar 4 until the collar of the
protection guard rests on the flange of the power tool.
– Adapt the position of the protection guard to the require-
ments of the work step.
– Lock the clamping lever 9.
You can change the clamping force of the clasp on the protec-
tion guard 6 by loosening or tightening the adjustment screw
7. Ensure that the protection guard 6 is seated firmly and
check this regularly.
