Always be sure to use a torque screw-
driver to check the tension of the port re-
tainer screws. Overtightening can cause
damage to the threaded inserts in the
fiberglass shell and cause them to loos-
en. Without the correct tension the port
retainer may come loose and the helmet
could flood. This could lead to drown-
ing.
WARNING
6) Using a torque screwdriver slightly tighten each
opposing screw evenly, i.e. 12 o’clock position,
6 o’clock position, 9 o’clock position, 3 o’clock
etc.. Repeat this process, one after another, until all
screws are evenly torqued to 12 inch pounds and the
O-ring has completely sealed the face port.
NOTE: Testing of the inserts should be performed
once a year or whenever damage is suspected. Part
#525-115 Thread Insert Testing Block Kit.
When testing the thread inserts, or when removing
and replacing the port retainer, it is crucial that the
KMDSI recommended torque specs be followed
when tightening the port retainer screws. Any over
torque of a screw greater than 14 inch pounds can
result in serious damage to the surrounding fiber-
glass in the port area. This can lead to loosening of
the port retainer and in extreme instances to flood-
ing of the helmet.
that have been damaged, or become loose, requir-
ing replacing. Replacement of inserts should only
be completed by an authorized /trained KMDSI
technician that has received certification in insert
replacement. Minor fiberglass and gel coat repairs
must only be completed by technicians that have re-
ceived fiberglass and gel coat training and certifica-
tion by KMDSI.
7) Install the nose block device from the interior of
the oral nasal mask and out through the nose block
guide on the port retainer.
8) Slide the two lubricated O-rings onto the shaft of
the nose block device.
9) The packing nut is threaded into place followed
by the nose block device knob.
10) Tighten the packing nut until some resistance is
felt when the nose block device knob is pushed in
and out. Tighten the nut until it cannot be loosend
by hand, then another half turn. If the packing nut
is too tight the nose block device cannot slide in and
out.
11) The nose block device knob should be tightened
to the shaft using a padded pair of pliers, while hold-
ing the nose block pad on the inside of the helmet.
The face port is very
strong. However, cer-
tain chemicals will
attack the port and
weaken it. Some sol-
vents used for lu-
bricant removal will
also attack the port.
Use only mild soap
WARNING
solutions to clean the face port. Improp-
er application of cleaning agents may
cause the port to fail without warning.
This could lead to drowning.
Always use a torque screwdriver to check the
tension of the port retainer screws.
