If sensors are loose,
steam and hot water
can pour out of their
connections and burn
you. Have DS tighten
them if they're loose.
Over time, sediment and rust
build up in the ports of the quick
disconnects and block water flow.
That strains the water pump and
eventually kills it. Run your wire
brush in and out of the ports to
break up sediment and then flush
out the system with clean water.
If the ports are
blocked, you've got a
fire waiting to happen.
Clear out any leaves or
dirt in the ports.
Optical inserts
The optical insert, NSN 4240-01-443-5489, which
is listed in the -10’s AAL brings just a frame with-
out lenses. To order the inserts, go through your
local opthalmic services. They should follow the
instructions in Chapter 2 of AR 40-63,
Opthalmic
Services,
to get the inserts.
Disk valve
The disk valve listed in the
M45’s TM 3-4240-341-10
is no longer available.
Instead, use the M40/M42’s
disk valve, NSN 4820-01-
260-8709.
If your
unit uses m45

protective
masks, note this
