depends on how well all parties, i.e. the manufac
turer, the owner and the machine operators, work
together to uphold safety standards.
All laws and regulations (e.g. the valid regulations on
waste disposal), accident prevention guidelines and
generally recognised safety rules must be complied
with when working on and with the machine!
2.2 Safety instructions
This machine incorporates state of the art technology
and has been built in accordance with recognised

ried out only by qualified personnel!
A visual inspection of the machine needs to be
done before starting up the machine.
Particular attention should be paid to damaged
or loose components, wearing and filling levels.
Always use ETX diamond tools or abrasive bonding
for the surface to be machined (e.g. some surfaces
have to be ground wet).
1. Check the surface to be ground and remove any
protruding objects.
2. Loosen the clamping screw [15, Fig. D], adjust
the guide bar [3, Fig. D] to the appropriate work
position and retighten the clamping screw.
3. Check ETX diamond tools for function and con
dition and replace if necessary.
