System pressure check (Item 1)
1. Check the reading on the pressure indicator located on the cylinder valve of each cylinder assembly installed.
The pressure should read within the green segment of the indicator.
2. Check the reading on the pressure indicator located on each LOP manual actuator installed. The pressure
should read within the green segment of the indicator.
3. If system is low on pressure, the source of the leak should be identified and rectified prior to re-pressurising the
system.
4. If the system pressure shows 0kPa, it is likely the system has been discharged and will need to be refilled.
5. If a pressure indicator reads differently to all of the other pressure indicators, this pressure indicator is most
likely faulty or out of calibration. Replace the faulty pressure indicator. Refer to section on valve service and
actuator service located later in this manual.
