1.3 Possible dangers caused by the grinder
The grinder has undergone a safety inspection (analysis of danger with assessment of risks).
Design and construction based on this analysis were carried out with the latest technological
advances.
Nonetheless, there remains a residual risk, given that the grinder features
• high revolutions,
• rotating parts
• grinding wheels (emission of sparks)
• electrical voltage and currents.
We have used construction resources an d safety techniques to minim ise the health risk to per-
sonnel resulting from these hazards.
If the grinder is used by personnel who are not duly qualified, there may be a risk resulting from
incorrect operation or unsuitable maintenance.
INFORMATION
All personnel involved in assembly, commissioning, operation and maintenance must
• be duly qualified,
• follow this instruction manual.
In the event of improper use
• there may be a risk to personnel,
• there may be a risk to the machine and other items,
• correct functioning of the grinder may be affected.
Disconnect the machine whenever cleaning or maintenance work is being carried out.
WARNING!
