Possible dangers caused by the drill bit grinder
The drill bit grinder is state of the art.
Nevertheless, there is a residual risk as the drill bit grinder operates with
high revolutions,
rotating parts,
an abrasive wheel (flying sparks)
electrical voltage and currents.
We have used construction resources and safety techniques to minimize the health risk to persons resulting from these hazards.
If the drill bit grinder is used and maintained by personnel who are poorly qualified, then there
may be a risk resulting from incorrect operation and unsuitable maintenance.

be duly qualified,
strictly follow this operating manual.
Due to improper use
there is a risk for personnel,
