WARNING
·
The LHS hydraulic system operates at oil pressures up to 1,725 psi (11 894 kPa).
Never disconnect any hydraulic line or fitting without first dropping pressure to
zero. Failure to comply may result in serious injury or death to personnel.
·
Fuel and oil are slippery and can cause falls. To avoid injury, wipe up spilled fuel or
oil with rags.
NOTE
·
Shut off engine (TM 9-2320-279-10) to connect gage.
·
Hose 2917 is disconnected while installing and removing pressure gage. Hose 2917
must be connected during test.
Step 2. Check hydraulic pressure at main manifold, port TPMA, with hoses 2888, 2887, 2588,
2666, 2889, and 2890 capped and LHS joystick held in LOAD position.
If 1,725 psi (11 894 kPa) is not present, replace LH (outboard) main frame cylinder
manifold load control valve (Para 5-41).
