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 "After-
sales Service and Application Service".
Protection Guard for Grinding
Place the protection guard 5 on the spindle collar. 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 manner that
sparking is prevented in the direction of the operator.
Protection Guard for Cutting
 For cutting with bonded abrasives, always use the pro-
tection guard for cutting 13.
 Provide for sufficient dust extraction when cutting
stone.
The protection guard for cutting 13 is mounted in the same
manner as the protection guard for grinding 5.
Cutting Guide with Dust Extraction Protection Guard
The cutting guide with dust extraction protection guard 24 is
mounted in the same manner as the protection guard for
grinding 5.
Auxiliary Handle
 Operate your machine only with the auxiliary handle 3.
Screw the auxiliary handle 3 on the right or left of the machine
head depending on the working method.
Hand Guard
 For operations with the rubber sanding plate 20 or with
the cup brush/wheel brush/flap disc, always mount the
hand guard 18.
The hand guard 18 is fastened with the auxiliary handle 3.
