WARNING - EYE HAZARD
There may be remaining air pressure inside the upper post assembly. Keep your eyes and face away from the poppet valve housing during
disassembly.
Use an 11 mm open end wrench to hold the poppet valve housing in
place. Use a 10 mm open end wrench to unthread the poppet valve
cover from the poppet valve housing three full turns. Do not remove
the poppet valve cover.
Wrap a rag over the poppet valve cover. Unthread the poppet valve
cover slowly by hand. Remove the poppet valve cover from the poppet
valve housing slowly and cover the poppet valve housing opening with
the rag.
⚠
WARNING - EYE HAZARD
In the event there is any remaining air pressure inside the upper post
assembly, covering the poppet valve housing with a rag will prevent
the poppet valve from discharging from the housing during removal.
With a rag around the poppet valve housing, use needle nose pliers to
remove the poppet valve from the housing and inner shaft.
