3.5 Pre Dress-In Procedure
Before dressing in for a dive, inspection of the helmet
systems must be made to be sure it is in proper work-
ing order. This must be done well in advance of the
dive so any problems can be fixed without delaying
the dive. The following steps are part of the recom-
mended daily maintenance.
3.5.1 Pre-Dive Visual Inspection
Visually inspect the exterior and interior of the hel-
met.
1) The demand regulator cover assembly should not
have excessive dents or dents deeper than 1/4”. The
purge button must operate freely and should have no
less than 1/16” and no more than 1/8” inward travel
before gas flow is heard.
WARNING
There must be no holes in the neck dam.
If there are any holes in the neck dam the
helmet could leak or flood. In addition,
the demand regulator will not operate
properly. Drowning could result.
2) The neck dam must not be torn or punctured, and
properly trimmed to fit.
3) Inspect the O-ring on the bottom of the helmet
shell. The O-ring must be in place and undamaged.
4) Inspect the bent tube that supplies breathing gas
to the regulator. There must be no dents or kinks in
the assembly, or visible signs of damage.
5) Inspect the face port. It must be in good condition.
6) Be sure the communications wires are hooked up
and tested.
7) Inspect the oral nasal mask. Make sure it is on
the regulator mount nut properly and the valve is
installed properly.
8) Make sure the head cushion is properly fastened
inside the helmet.
9) Check the screws on the port retainer . They must
be adjusted to the proper torque setting specifications
noted in Appendix 1 of this manual.
The O-ring on the base of the helmet
shell on the SuperLite
®
-17B must be in
place and in good condition. Without a
proper functioning O-ring the helmet will
leak and possibly flood. Drowning could
result.
WARNING
All parts on Kirby Morgan diving helmets
must be adjusted to their proper torque
specifications. See Appendix 1 for a
complete listing of torque specifications
for each part. Failure to adjust parts to
the recommended specifications could
lead to helmet failure and accidents. This
could be fatal.
WARNING
Binder head screws are used in this application for
their self locking characteristics. Overtightening may
strip out the threaded inserts in the helmet shell.
10) Make sure the head cushion is properly fastened
(snapped) inside the helmet to the snap tabs.
11) Make sure the chin strap is the new version that
bolts directly inside the helmet with tab bolts. If the
older system is used where the chin strap is part of
the head cushion, replace it as soon as possible.
12) Make sure the strap guide and yoke strap that help
secure the helmet are in place and in good condition.
