Diving With Your Regulator

Before each use, it is important to perform a complete pre-dive inspection
of your regulator. NEVER dive with a regulator that shows signs of
damage or unsatisfactory performance until it has received complete
inspection and service from an authorised dealer.

Pre-Dive Inspection Checklist:

1. Carefully inspect all hoses at their fittings to ensure they are securely
connected into their respective ports on the first stage. Inspect the
length of each hose to ensure that the hoses are not blistered, cut,
or otherwise damaged. If hose protectors are present, slide the
protectors back to expose the hose fittings, and inspect the hoses as
described above.
2. Visually inspect both the first and second stage regulators for any
signs of external damage.
3. Environmentally sealed first stages only: Closely inspect the external
sealing diaphragm for any signs of damage or deterioration that may
cause leakage. Check to ensure that the retainer which holds the
external diaphragm in place is tightly secured.
WARNING: If the external diaphragm shows any signs of damage
or neglect, DO NOT attempt to dive with the regulator until it has
received factory prescribed service from an authorised dealer.
The regulator's performance may be compromised, and first
stage freeze-up could occur in cold water conditions.
4. Connect the first stage regulator to a fully charged SCUBA cylinder.
(For mounting instructions, read the Setup section on pages
21-24.) SLOWLY open the cylinder valve to pressurise the regulator.
Continue turning the valve anti-clockwise until it stops. This is to
ensure that the valve is completely open.
5. If present, turn the inhalation control knob completely "out" (anti-
clockwise), and then back "in" (clockwise) until the regulator provides
maximum ease of breathing with no leakage present. Do not apply
excessive pressure.
