Risk of bursting in the actuator.
Actuators are pressurized. Improper opening
can lead to actuator components bursting.
Before starting any work on the actuator, de-
pressurize all plant sections concerned and
the actuator.
Risk of personal injury due to preloaded
springs.
Actuators with preloaded springs are under
tension. They can be identified by the long
bolts protruding from the bottom of the
actuator.
Before starting any work on the actuator, re-
lieve the compression from the preloaded
springs (see section 9.3).
Risk of actuator damage due to incorrect
service or repair.
