Noise/Vibration Information

Measured sound values determined according to EN 60745.
Typically the A-weighted noise levels of the product are: Sound pressure level 93 dB(A); Sound power level 104 dB(A). Uncer-
tainty K =3 dB.

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.

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 ser-
vice agent for maintenance. For addresses, see section "Af-
ter-sales Service and Application Service".
Protection Guard for Grinding
Release the clamping lever 8. Place the protection guard 6
with the encoding key 7 engaging into the groove on the spin-
dle collar until the shoulder of the protection guard is seated
against the flange of the power tool, and turn the protection
guard 6 to the requested position. Lock the clamping lever 8.
 Adjust the protection guard 6 in such a manner that
sparking is prevented in the direction of the operator.
The tightening tension of the clamp from the protection guard
6 can be changed by loosening or tightening the adjustment
screw 9. Ensure that the protection guard 6 is tightly seated
and check regularly.
Note: The encoding keys on the protection guard 6 ensure
that only a protection guard that fits the machine type can be
mounted.
Protection Guard for Cutting
 For cutting with bonded abrasives, always use the pro-
tection guard for cutting 15.
 Provide for sufficient dust extraction when cutting
stone.
The protection guard for cutting 15 is mounted in the same
manner as the protection guard for grinding 6.
Cutting Guide with Dust Extraction Protection Guard
The cutting guide with dust extraction protection guard 22 is
mounted in the same manner as the protection guard for
grinding 6.
Auxiliary Handle
 Operate your machine only with the auxiliary handle 4.
Screw the auxiliary handle 4 on the right or left of the machine
head depending on the working method.
