Noise/Vibration Information
The vibration emission level given in this infor-
mation sheet has been measured in accordance
with a standardised test given in EN 60745 and
may be used to compare one tool with another.
It may be used for a preliminary assessment of
exposure.
The declared vibration emission level repre-
sents the main applications of the tool. However
if the tool is used for different applications, with
different accessories or poorly maintained, the
vibration emission may differ. This may signifi-
cantly increase the exposure level over the total
working period.
An estimation of the level of exposure to vibra-
tion should also take into account the times
when the tool is switched off or when it is run-
ning but not actually doing the job. This may sig-
nificantly reduce the exposure level over the to-
tal 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 patterns.

Assembly
f
Before any work on the machine itself, pull
the mains plug.
Mounting the Grinding Tools
(see figure A)
– Clean the grinder spindle
3
and all parts to
be mounted.
– Hold the grinder spindle
3
on the spanner
surfaces with the open-end spanner
7
(size
17 mm).
– Loosen the clamping nut
2
with the open-end
spanner
7
(size 17 mm) by turning in anti-
clockwise direction.
– Insert the clamping shaft of the grinding tool
to the stop into the collet chuck
1
.
– Tighten the clamping nut
2
with the open-
end spanner
7
(size 17 mm) by turning in
clockwise direction.
