OXYGEN SYSTEM
SERVICING
The oxygen cylinder, when fully
charged, contains 48 cubic feet of
oxygen,
under a pressure of 1800 psi
at 70°F. It shruld be refilled, when-
ever the oxygen pressure gage indi-
cates less than 300 psi, with aviators'
breathing oxygen (Fed. Spec. No.
BB-O-925,
or equivalent). For serv-
icing convenience, a filler valve is
