e. If pneumatics are required, perform the following
procedures:
(1) Layout the pneumatic hose in a manner which
would prevent kinks and loops.
(2) Attach pneumatic hose coupling to aircraft air
nipple (TM 1-1520-238-23).
WARNING
Never set PNEUMATIC POWER switch to
ON unless pneumatic hose coupling is
securely attached to the aircraft. The hose
will attempt to straighten out with power
applied, and whip around violently if not
securely attached to the aircraft. Wear
proper gloves and eye protection (goggles
or equivalent) when operating the
pneumatic system.
AGPU operation exceeds acceptable safe
noise levels. Personnel working near or
operating will wear approved ear
protection to protect their hearing. Failure
to comply could result in permanent
hearing loss.
CAUTION
Handle pneumatic hose with care so spiral
wrap and netting are not damaged. Keep
hose off ground if wet or muddy (Use
suitable supports).
NOTE
The SHAFT DRIVEN COMP indicator on the
pilot caution/warning panel does not light when
the pressurized air system (PAS) manifold is
pressurized.
(3) Apply pneumatic power via the PNEUMATIC
control panel on the AGPU (refer to
TM 55-1730-229-12 for operator and AVUM
maintenance instructions on the AGPU).
