Check the neck dam for holes and compress
between the rings.
Inspect the o-ring on the neck dam ring.
The nose block o-rings must be regularly
lubricated.
Never patch a torn or punctured neck
dam. If the patch comes off underwater
the helmet could flood and/or the demand
regulator assembly may not function
properly. A damaged neck dam must be
replaced.
WARNING
6.5.3 Head Cushion and Chin Cushion
Remove the foam from the head cushion and inspect
it for wear. If the foam is worn or crumbling it must
be replaced (order Part #510-672).
Inspect the chin cushion. It, too, must be in good
condition. Replace it if the foam is worn or has started
to crumble.
6.5.4 Communications Inspection
Visually inspect the earphones, microphone, wires,
lugs, and communications posts if installed. Test
each component for proper operation. Connect to the
deck amplifier and talk back and forth. Replace any
weak earphone or microphone. Open the earphone
rubber covers and remove the protectors. Allow to
dry thoroughly. Replace defective earphones.
6.5.5 Lubricate Nose Block O-Rings Tools
Required:
7/16 inch Open End wrench
1) Unscrew the nose block device packing nut and
lubricate the two o-rings and nose block device shaft.
Retighten the packing nut just to the point where the
nose block device will still slide, but requires a firm
push or pull.
2) Test the nose block shaft to ensure that it will
still slide freely at this time. If it does not, loosen
or tighten the packing nut just enough to permit the
shaft to slide properly.
6.5.6 Inspect the Exhaust Valve
1) Remove the exhaust cover from the exhaust body
by removing the tie wrap.
2) Inspect the exhaust valve and valve bodies for
cracks or tears, replace if needed. Lubricate the valve
with a small amount of silicone lubricant. Rub the
lubricant into the valve thoroughly leaving no excess
lubricant to collect sand or other debris. Replace the
cover and replace the tie wrap.
