Supports and trolleys

recommended by the manufacturer. The equipment / support / trolley assembly must be
moved with extreme caution.
Sudden stops, excessive pushing force and uneven floors may cause the assembly to overturn.
10.
Hearing loss
Exposure to high sound levels can cause permanent hearing loss. The acoustic pressure level
that leads to hearing loss is different from person to person and depends on the duration
of exposure. To prevent potentially dangerous exposure to high levels of acoustic pressure,
anyone who is exposed to these levels should use adequate protection devices.
When a transducer capable of producing high sound levels is being used, it is therefore
necessary to wear ear plugs or protective earphones. See the manual technical specifications
to know the maximum sound pressure level.
