3. Examine the cylinder to determine whether an Evidence
of Inspection (EOI) sticker is affixed, and the month and
year that the most recent visual inspection was per-
formed. (See Fig. 3.) If an EOI sticker is not present or
does not indicate that the cylinder has been inspected
within the past year, return it immediately to an Autho-
rized Aqua Lung Dealer to obtain visual inspection.
WARNING: DO NOT attempt to fill or use the M.A.S. if its
EOI sticker is not present or does not indicate that the cylin-
der has been inspected within the past twelve months by an
Authorized Aqua Lung Dealer or Professional Scuba Inspec-
tors (PSI) qualified facility. Doing so may result in rupture or
explosion, which could lead to serious injury or death.
4. Examine the position of the ON-OFF
indicator ring in relation to the indica-
tor pin to determine whether the valve
is open or shut. If necessary, turn
the first-stage clockwise while
holding the cylinder secure until it
stops and the indicator pin is posi-
tioned to the far right inside the
aperture marked "OFF." (See Fig. 4.)
5. Depress the second-stage purge
button to ensure that the system is
completely depressurized.
6. Apply a b" open-end wrench to the
pressure gauge assembly, located
between the HP port which contains
the safety disc assembly and the
low pressure port which contains
the LP hose swivel. (See Fig. 5.)
Turn the pressure gauge assem-
bly counter-clockwise to loosen
and remove from the first-stage.
7. Closely inspect the port opening
to ensure that no debris, residue,
or moisture is found to be
present.
