If pressure at BSI in stow range is less
than 385 psi, go to Step I. If pressure
at BSI in live range is greater than 60
psi, notify Direct Support Maintenance.
Go to
Step I.

no
yes
2. Disconnect hose from BLV port of hydraulic control
valve manifold assembly and plug hose with
1/4--inch plug.
3. Remove auxiliary winch cover (WP 0513 00) and
disconnect hose quick--disconnects at auxiliary
winch.
4. Start main engine, energize hydraulics system, and
set engine speed to 1800 rpm (TM
9--2350--292--10) and observe pressure at PR port.
5. Shut down hydraulic system and main engine
(TM 9--2350--292--10).
AA
Is pressure at boom safety valve ports BSI and BSO 60
psi or less with boom in live range and is pressure at
port BSI 385--470 psi and pressure at port BSO 60 psi
or less with boom in stow range?
1. Remove plug and reinstall hose to BLV port of
hydraulic control valve manifold assembly.
2. Start main engine, energize hydraulics and set
engine speed to 1800 rpm
(TM 9--2350--292--10).
3. Operate boom (TM 9--2350--292--10).
4. When boom is in live range, place boom safety
valve lever to stow position, retract boom, and
record pressures at BSI port of boom safety
and BSO port of boom safety valve while in live
range and again in stow range.
5. Shut down hydraulics and main engine
(TM 9--2350--292--10).
Notify Direct Support
Maintenance.
