●
Conductive dust may accumulate inside the tool when working on conductive mate-
rials, resulting in a short circuit or breakdown of the tool’s protective insulation and
thus present a risk of electric shock. Accordingly, the tool must be inspected and its
insulation resistance tested at frequent intervals by a trained specialist at a Hilti repair
center in order to ensure that the tool is free from accumulations of conductive dust
or other conductive deposits.
●
An industrial vacuum cleaner equipped with filters of a type suitable for the mate-
rial worked on must be used when grinding.
●
Before beginning the work, determine to which class of risk the resulting dust will
belong. Always wear eye protection and ear protection. Other personal protective
equipment such as breathing protection, protective gloves, special overalls and safe-
ty helmet should be worn as necessary. When assessing whether breathing protec-
tion or a full face mask (respirator) should be worn, the hazardous characteristics of
the material to be cut or ground as well as any coatings applied to it should be taken
into account. In cases of doubt, full protective equipment should be worn. Use an
industrial vacuum cleaner, with an officially approved protection classification, which
complies with the local dust control regulations.
