5.3 PUTTING ON THE FULL-FACE MASK
1. Pressurize the Divator diving apparatus according to the description in Section 5.1 “Leakage and func-
tion test”. If the Divator fresh air hatch is used, it should be opened.
2
. Pull out the rubber straps on the rubber-band device as far as possible by grasping the metal buckles and
pulling them out.
3
. Adjust the pressure equalization cushion (there
are several positions) so that it is easy to reduce
the pressure in your ears and breathe through
your nose unimpeded. Check that the pressure
equalization cushion is correctly secured.
4
. Don the Divator full-face mask by grasping the
two lower rubber straps of the head harness and
pulling it over your head.
5
. Properly press your chin down into the mask's
chin support. Press the mask tightly against your
face to form a seal.
WARNING! Make sure that the inner mask is correctly
positioned. If this is not done correctly, high levels
of CO
2
may build up, which will increase breathing
frequency, give rise to panic and may even result in
a fatal accident.
Pull down the rear part of the strap device as far
as possible and check that no rubber straps have
become twisted.
6
. Adequately tighten the rubber straps by pulling
them straight back, not outwards. Begin with the
two lower straps, then the two upper side straps
and nally the top strap at the forehead. Make
adjustments where necessary.
WARNING!Some neoprene hoods become compressed as the diving depth increases. When these hoods are used,
you must continue to adjust the rubber straps during the dive. The neoprene hood should also have a smooth
edge to provide an adequate seal against the full-face mask. If this is not done correctly, high levels of CO
2
may
build up, which will increase breathing frequency, give rise to panic and may even result in a fatal accident.
