3.1 Starting up the machine
Observe the safety instructions in Chapter 2!
The initial start-up of the machine may be car
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).

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.
