Dismantling and Demolition
!
WARNING
Before disassembling the actuator it is necessary to close the pneumatic feed line and
discharge pressure from the cylinder of the actuator, from the control unit and from the
accumulator tank, if present.
!
WARNING
The demolition of the actuator both concerning any electrical and mechanical parts should
be made by specialized staff.
Before starting the disassembly a large area should be created around the actuator so to
allow any kind of movement without problems of further risks created by worksite.
Separate the parts composing the actuator according to their nature (ex. metallic, and
plastic materials, fluids etc.) and send them to differentiate waste collection sites, as
provided for by the laws and provisions in force.
