Noise/Vibration Information
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
 Before any work on the machine itself, pull the mains
plug.
Inserting/Replacing Diamond Cup Wheels
(see figure A)
Approved Grinding Tools
All diamond cup wheels mentioned in these operating instruc-
tions can be used.
Observe the dimensions of the diamond cup wheels. The
mounting hole diameter must fit the mounting flange without
play. The mounting hole of the diamond cup wheel may not be
increased. Do not use reducers or adapters.
The permissible speed [rpm] or the circumferential speed
[m/s] of the diamond cup wheels used must at least match
the values given in the table.
Therefore, observe the permissible rotational/circumferen-
tial speed on the label of the diamond cup wheel.
Inserting Diamond Cup Wheels
Select a suitable diamond cup wheel for the material to be
worked. Please also observe the material information on the
packaging of the diamond cup wheel.
Clean the grinder spindle 13 and all parts to be mounted.
Place the mounting flange 14 on the grinder spindle 13 so
that the centring collar faces away from the machine. The
mounting flange must engage on the flats of the grinder spin-
dle (anti-twist protection).
