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.
·
Do not get under LHS when disconnecting or connecting connectors and hoses. A
hydraulic malfunction could cause LHS to lower causing serious injury or death.
NOTE
Hose 2917 is disconnected while installing and removing flowmeter. Hose 2917 must be
connected during test.
Step 6. Check hydraulic flow at LH hook arm manifold, port VA with LHS in transit position while
