WARNING
Do not tighten EBA fittings or connections when the system is pressurized. Close the cylinder valve and be sure nothing
blocks the regulator outlet, then relieve the pressure from the system by slowly opening the regulator valve. Failure to
depressurize the system prior to adjusting fittings may cause fittings to rupture, resulting in severe personal injury or
death.
(1) Check connections for tightness.
(2) Check for missing or worn out anti-seize tape at metal to metal connections.
(3) Inspect connections for thread damage. Replace the EBA if thread damage is identified. Notify your supervisor.
(4) If regulator leaks were identified, refer to paragraph 3-9. 2. 6 to replace the regulator.
(5) If filter housing leaks were identified, check the filter housing for damaged preformed packing and thread
damage. Refer to paragraph 3-9. 2. 2 to replace preformed packing. Refer to paragraph 3-9. 2. 8 to replace
