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
Place the protection guard 12 on-
to the spindle collar as shown in
the illustration. The triangle marks
on the protection guard must cor-
respond with the respective
marks on the gear case.
Press the protection guard 12 on-
to 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 protec-
tion guard 12 to the requirements
of the work process. For this, press the release lever 1 up-
ward and turn the protection guard 12 to the required posi-
tion.
 Adjust the protection guard 12 in such a manner that
sparking is prevented in the direction of the operator.
 The protection guard 12 may be turned only upon actu-
ation of the release lever 1! Otherwise the power tool
may not continue to be used under any circumstances
and must be taken to an after-sales service agent.
Note: The encoding keys on the protection guard 12 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 14.
 Provide for sufficient dust extraction when cutting
stone.
The protection guard for cutting 14 is mounted in the same
manner as the protection guard for grinding 12.
