General; Daily Maintenance - Kirby Morgan KMB-18 A/B Operation And Maintenance Manual

DANGER: In-water decompression
with oxygen is a specialized procedure.
All parts of the diving system must be
oxygen compatible and cleaned for oxy-
gen service. Any parts of the system (i.e.,
manifolds, hoses, fittings, etc.) which are
exposed to compressed air must be con-
sidered contaminated and should not be
used again until cleaned for oxygen ser-
vice.

5.3 GENERAL

Each diver must follow the minimum standards
for the care of his/her Band Mask. We offer
recommendations here with the suggestion that
the diver establish for himself what ever addi-
tional service is necessary to provide a good
working unit. Use of the Band Mask in fresh
water will require a timetable for maintenance
procedures different from that when the Band
Mask is used in salt water. Using the Band Mask
in sea water while jetting in sand will necessitate
increased maintenance. Use of the Band Mask in
a heavy oil environment or other chemicals will
make it necessary to replace rubber parts on a
regular basis.

5.4 DAILY MAINTENANCE

The following steps should be performed daily at
the completion of diving operations.
1) Disconnect the Band Mask from the diving
hose and bail-out bottle. Make sure the air is off
and the breathing system of the Band Mask is
unpressurized. To vent the system, open the free
flow valve knob (85) and auxiliary valve knob
(100) until all gas flow stops.
WARNING: Never disconnect any
hose from the Band Mask unless all gas
has been vented from the hose first. If the
hose is disconnected with pressure in the
line the fittings may be damaged. In addi-
tion, the hose can whip about causing
injury to anyone standing nearby.

2) Place a protective cap over both the air inlet
(105) and the auxiliary valve inlet (95) to prevent
foreign matter from entering the valves.
Fig. 5.2 Always cap the gas inlet adapter (105) and the
auxiliary valve inlet (95) when the mask is not in use.
3) Remove the hood (2) from the mask by un-
screwing the band screws (15) and removing the
top and bottom bands (16,68). Slide the ear-
phones (10,11) out of their pockets in the hood
(2). Remove the earphone covers from the ear-
phones (10,11) so they can dry completely. Avoid
getting water on the oral nasal microphone (12)
and earphones (10,11), whenever possible.
