WARNING
Avoid personnel injury or property damage from sudden release of process
pressure or uncontrolled movement of parts. Before performing any
maintenance operations:
• Always wear protective gloves, clothing, and eye wear.
• Disconnect any operating lines providing air pressure, electric power,
or a control signal to the actuator. Be sure the actuator cannot
suddenly open or close the valve.
• Do not remove the actuator from the valve while the valve is
still pressurized.
• Vent any pneumatic pressure from the actuator and relieve any
actuator spring pre-compression.
• Use lock-out procedures to be sure that the above measures stay in
effect while you work on the equipment.
• Never apply pressure to a partially assembled actuator unless all
pressure-retaining parts have been installed properly.
• Check with your process or safety engineer for any additional
measures that must be taken to protect against process media.
• Do not remove the Pistons from the Actuator Body by using air
pressure when the End Caps have been removed.
!
CAUTION
Do not turn out the travel stops completely when the actuator is pressurized.
When adjusting the travel stops and the actuator is still pressurized, the travel
stops can "shoot" away when completely turned out.
