1.4 Possible dangers caused by the grinding machine
The grinding machine was built using state-of-the-art technology. Nevertheless, there is a resid-
ual risk, as the grinding machine operates with
high speeds,

rotating parts,

one grinding wheel (emission of sparks),

one cleaning brush,

electrical voltage and currents.

We have used design and safety engineering to minimize the health risk to personnel resulting
from these hazards.
If the grinding machine is used and maintained by personnel who are not duly qualified, there
may be a risk resulting from its incorrect or unsuitable maintenance.
INFORMATION
Everyone involved in the assembly, commissioning, operation and maintenance must
be duly qualified,

and strictly follow these operating instructions.

Always disconnect the grinding machine from the electrical power supply before performing
cleaning or maintenance tasks.
WARNING!
The grinding machine may only be used with fully functional safety devices.
Disconnect the grinding machine immediately, whenever you detect a failure in the
safety devices or when they are not fitted!
