Manual Actuators (Item 5)
WARNING: The cylinder and actuation pipework contains high pressure. Do not remove any parts from
the cylinder or actuation pipework unless it is depressurised first.
Note: The LOP Manual actuators are designed to “fail to safe”. That is any fault causing leakage will activate the
system. As such the LOP Manual actuators may be considered operational if the below listed checks are carried
out.
1. Check that all actuators are intact and not damaged.
2. Check that all actuators are accessible and access has not been restricted by equipment modification.
3. Check that all pull pins and security ties (anti tamper seals) are in place and secure. Replace security ties if
missing or broken.
4. Check that the pull pin retainer wire is correctly securing the pull pin to the actuator.
5. Check to ensure pressure is reading in the green sector of the pressure indicator
6. Remove the front housing cover and check that all actuators are:
a. Clean and undamaged.
b. Foil is intact on outlet port nozzle. Replace if required.
c. Schrader Valve has cap fitted to protect against ingress of dust and dirt.
7. Check that all actuators are adequately secured to the equipment.
